CONDIŢIILE TERMICE ALE METAMORFISMULUI UNITĂŢII GNAISELOR DE RARĂU – HĂGHIMAŞ

Constantin CĂTANĂ

 

Abstract: The thermals conditions of the metamorphism’s gneisses from the Rarău-Hăghimaş unit. The quantitative proportions of certain chemical elements in the composition of minerals reflect the conditions of the metamorphism in witch the latter were formed. Perciuk (1968) obtained a series of diagrams of correlation between the formation temperatures and certain quantitative proportions of the elements. Thus, as far as the gneisses of Rarău-Hăghimaş of the Bretila group are concerned, the result by using the above mentioned diagrams, shows that the temperature of the metamorphism in the formation of the respective minerals must have been 630 – 680ºC

RISCURILE NATURALE DIN JUDEŢUL BIHOR

Nicolae Josan 

 

Rezumat: Riscurile naturale din judeţul Bihor. Conform Teoriei Generale a Sistemelor, orice sistem disipativ posedă bifurcaţii, iar toate aceste sisteme vor avea elemente deterministe şi elemente probabiliste. Legile procesului probabilist guvernează dinamica sistemului între bifurcaţii. În vecinătatea bifurcaţiilor - unde schimbarea în traiectoria dinamicii este abruptă – acţionează fluctuaţiile care au posibilitatea să joace un rol dominant în determinarea traiectoriei sistemelor. Elemente determinante ale geosistemului vor fi conţinute în ecuaţiile procesului care descrie transformările şi transferurile variate ce au loc în sistem. Fluctuaţiile care declanşează trecerea pragurilor în sistem pot fi de origine internă sau externă. Caracterul şi efectul lor în decursul schimbărilor  sistemului sunt în mare măsură neprevăzute. Orice sistem geomorfologic cu bifurcaţii va avea deci două categorii de elemente distincte: unele universale şi necesare, care sunt deterministe şi previzibile în natură şi elemente întâmplătoare care sunt probabile şi neprevizibile. La o bifurcaţie, un sistem corespunde la o fluctuaţie prin luarea unei noi forme. Cu alte cuvinte, comportamentele sistemului sunt reordonate, dar în ele există încă o instabilitate declanşată de o fluctuaţie care determină o reorganizare a sistemului. Aceasta poate fi cauzată de o scurtă schimbare în funcţionarea unei variabile a sistemului, care însă poate determina o modificare bruscă şi de amploare în comportamentul acestuia.  Cum însă sistemele geografice sunt compuse din lanţuri (catene) legate între ele, produsul unui subsistem poate deveni parţial sau total sursă de alimentare pentru un alt subsistem, declanşînd reacţii de răspunsuri complexe ale acestuia din urmă. În acest spirit,  ne propunem să analizăm în continuare factorii intrinseci şi extrinseci – ai subsistemelor geografice din judeţul Bihor care pot cauza fluctuaţii într-un sistem cu ecou şi în alte subsisteme cu care acesta are legături.

RAPORTURI MORFOSTRUCTURALE – MORFOSCULPTURALE ÎN PERIMETRUL STRUCTURILOR DOMALE: CRISTUR ŞI BUNTEŞTI

Ioan Aurel Irimuş

 

Abstract: Morphostructural and morphosculptural approaches of the dome structures from Cristur and Bunteşti area. From a geographical point of view, the Cristur and Bunteşti domes to the South – East group while from tectonic point of view belong to the some anticline fold with a devious shape, witch connects the following structures Miercurea Niraj, Chedea Mare (in the North); Cristur, Bunteşti (in the centre) and goes down to Văleni – Rodbav (in the South).The geomorphologic research was concerned with the tectonic and neotectonic impact considering the hydrographical net configuration, the genesis and evolution of the terraces, the slope’s dynamics, and the dynamics of the present processes.


 

PROFILE LONGITUDINALE ŞI CONFLUENŢE DE VĂI ÎN PODIŞUL MOLDOVEI

Marcel Vârlan, Mihai Apetrei

 

Abstract: Longitudinal Valley Profiles and Valley Confluences in the Moldavian Plateau. 54 valleys of different Horton orders were selected for study in the Moldavian Plateau. In each of these measurements were made on valley length, on the valley length, on the valley axis. Long profiles were plotted and pseudo-hypsometrical integrals computed. The data indicates profiles of different shapes – from generally concave to generally convex. On the other hand, a minute analysis points out, on many on the concave profiles, some convexities in the low section and more convex steps along the valley, often related to confluences. In addition, the valleys generally convex and convex in the lower section represent 44 events, or 81,5%. There isn’t a clear relationship between convexity, on the one hand, and valley length and Horton order, on the other hand. Rather, the valleys being generally concave. The analysis of Bârlad floor points out the same behaviour. Finally, the pseudo-hypsometrical integrals (PIH) were computed. Taking into consideration all the studied valleys, one can get a negative significant correlation coefficient (r = -0, 37) between PIH and valley length.


 

FLUCTUAŢII RECENTE ALE CLIMATULUI PE GLOB, CU REFERIRI LA ACCENTUAREA GRADULUI  DE ARIDITATE DIN ULTIMUL DECENIU ÎN ROMÂNIA

Ana Popovici, Petru Ţuinea, Alexandru Geicu

 

Abstract: Recent variations of world s climate with special analisys of the incresing of aridity index in the last decade in Romania. Climatic anomalies, i.e. the year – to – year persistence of a scanty rainfall regime, sometimes particularly severe have afflicted numerous regions of the world through the last decade, while in the arid zones drought has set on ever since the end of the sixties persisting up to the present. To Romania, very meaningful in this respect is the aridity index distribution map, computed for the 1901 – 1980 intervals as against the 1981 – 1993 periods, when an extension is noticeable towards the interior of country of curves with high aridity indices. The precipitation decrease tendency was also stressed by the secular trend of the running means and of the standardized precipitation indices.


 

CARACTERISTICILE TOPOCLIMATICE ALE  RELIEFULUI ANTROPIC

Octavia Bogdan, Elena Niculescu

 

Abstract: Topoclimatic features of the anthropic relief. The man-made relief – the outcome of it activity upon the local geographical landscape – causes obvious changes in the active surface structure, which generates topoclimates. Instrumental observations on topoclimatic profiles and different weather types have revealed specific quantitative and qualitative differences, e.g. temperature inversions generated by evaporations generated by evaporation processes above water and irrigated areas and strong thermal convection over water – free zones, depending on the physical particularities of the rock substrate (sand, gravel, waste dumps, etc.) with high vertical thermal gradients within the first 20 cm; the shelter provided by the positive anthropic relief on wind-sheltered slopes and high aeration at about 2m above it (especially on the Danube Delta dykes) exit where no obstacles and isotherms run parallel to their surface. In embanked enclosures, highest temperatures develop inside the dams, with dryness increasing from the bottom to the top.

CULOARUL OLTULUI O ’’AXĂ’’ DE DISCONTINUITATE TOPOCLIMATICĂ

Octavia Bogdan

 

Abstract: The Olt corridor - ``axis`` of topoclimatic discontinuity. Like wise depressions valley corridors have a negative relief, which makes them areas of discontinuity and of topoclimatic discontinuity, par excellence. A traversal valley through out with a N-S orientation and rectilinear route, the Olt Valley is by similitude with the circulation axis – an ``axis`` of topoclimatic discontinuity. This assertion is based on the flowing criteria: its relative landform, relative alt. (2000m), a passageway for the air masses crossing it in relation to thermal – baric differences at their two extremities (fig.1); vertical thermal – baric contrast with those formed at the two extremities, generate mountain – valley winds; temperature inversion (fig.2), or isothermies inside it; three climatic influences: oceanic at the northern extremity , mountainous in the central portion and continental at the southern extremity. The slope of air temperature isoline (fig.3) of relative humidity (fig.4) and of precipitation (fig.5) stands proof to it.

Abstract: The influence of climatic conditions upon main human  biorhythms in Cluj Napoca town.This work treats the effect of the main climatic elements, characterizing the Cluj-Napoca area, on the human biorhythms, with a concrete view over the learning efficiency rhythm. We have studied curve of daily and annual learning efficiency and we have done a correlation between these data and the main climatic data. The conclusions revealed the possibility of studying, in detail, the favourable periods for school activities, the periods with maximum learning efficiency the climatic phenomena that could cause important oscillations in this biorhythm. 


 

NISTRU

Florina Bran

 

Abstract: Nistru. Nistru is the most important flow in Moldavia, representing a fundamental water Source for the industry, the agriculture, the centralized feeding of several towns as well as the water transport. But in the last ten years, a lot of activities have had negatively repercussions on the hydrological and sanitary conditions. This requires an adequate, treatment, including a proper disinfection so the water will be fit to drink. 


 

MODELUL MORFOMETRIC AL LUNGIMII REŢELEI DE RÂURI DIN BAZINUL HIDROGRAFIC AL DOFTANEI DE PRAHOVA

Iuliana Armaş

 

Zusammenfassung: Das hydrograpische Becken des Doftana Fluesses erstreckt sich im sued – westlichen Teil der Karpaten kruemmung, auf einer Oberflaeche von 419 Qkm. Die gesamte Umgebung ist von den neotektonischen Bewegungen stark betroffen, die auch die Entwicklung  des Flussnetzes beeinflusst haben. Der artkel stellt ein kurzen Ueberblik dar was die Faktoren, die Evolution des Flussnetzes bestimmen, anbetrifft. Die eigentliche Analyse befasst sich mit den morphometrischen Werte des Flussnetzes anhand des Klassifizierungsystems das von Horton und Strahler entwickelt wurde. Auf Grund topographischen Karten im Masstab 1:25.000,wurden drei wichtige Gesetze ueberprueft: die Anzahl verschiedender Flusssegmente, die gesammte Laenge des Flusssystems und ihrer Mittelwerte, die ierarhische Anordnung dieser Komponenten. Die territorielle Unterschiede und Ergebnisse die dabei erreicht wurden stellen die Anhangspunkte fuer eine richtige Stellungsnahme dar, was die Gelaendeforschung anbetrifft.


 

POTENŢIALUL EROZIV ŞI SCURGEREA DE ALUVIUNI ÎN SUSPENSIE PE RÂURILE DIN PODIŞUL TÂRNAVELOR

Victor Sorocovschi, Victor Buz

 

Abstract: The erosion potential and the alluvial runoff of the rivers in Tarnavelor tableland. Erosive potential and suspended alluvia flow on Podişul Târnavelor Rivers. Several areas with effective erosion were delimited having a weak up to excessive modelling. The human factor influences upon the transport and suspension sediment sources were evidenced specially after 1970. The territorial distribution of the alluvia flow was based on the graphical correlations with different conditional factors and on a multifactor numerical analysis. The temporary distribution of the alluvia flow analysis of the data processed between 1968 – 1988 evidences the decisive role of the climatic factors.          


 

PROBLEME GEOGRAFICE PRIVIND FONDUL FORESTIER ÎN JUDEŢUL BIHOR

Forian Benţe

 

Abstract: Geographical problems regarding forested areas in the Bihor county. In the Bihor county the forests cover almost 200000 hectares which represents approximately a quarter of the county areas that is slightly less than the national average. Present on all forms of relief, forests cover being formed mostly (85%) of decisions species. Coniferous species, mostly fir-tree are predominant in the eastern part of the county, in the Bihor and Vlădeasa mountains. The same differences can be noticed in administrative – territorial units depending on the rising of altitudes from west to east, from areas where the forest is absent like the Crişurilor Plain to forests which cover more then 3/4  of the area of some communes especially in the mountainous zone. Deforestation was relatively intense during the last years, and so was the replanting.     


 

ABUNDENŢA GEOGENĂ ŞI ANTROPOGENĂ A COBALTULUI ŞI NICHELULUI ÎN ROCILE ŞI SOLURILE BANATULUI

Gheorghe IANOŞ

 

Summary: The geogene and anthropogene abundance of cobalt and nickel within the rocks and soils of Banat area. The largest part of cobalt and nickel identified in the soils of Banat come out of the native currents in the primary rocks of the mountains in the Eastern and Southern part. The high concentrations in cobalt were identified in the exuded areas recently covered with clay soils in the gleic soils at the limit of the azonal limits, in the carbonadoed soils, etc. The abundance in nickel was   observed in the soils in the inner mountains depressions and in the vertic soils.   In the mentioned areals the percentage of cobalt and nickel are 5 to 3 times higher than for the other areas of the country anthropically not affected. 


 

FACETS OF THE ETHNICAL STRUCTURE OF URBAN POPULATION IN CLUJ COUNTY

Nicolae RABOCA, Iulius MOCREI

 

Abstract: Facets of the ethnical structure of urban population in Cluj County. The analysis of the ethnical structure of Cluj county population on the 1977 – 1992 time periods stresses out a comparatively high stability of nationalities and major numerical changes. In general there has been a numerical growth of most ethnical communities at the county level and the urban environment one, particularly. The urban settlements have become the main poles of ethnical concentration, holding greatest percentages of total county population.


  

ETNII ŞI CULTE RELIGIOASE ÎN VESTUL ROMÂNIEI

Nicolae Josan, Ribana Linc, Alexandru Ilieş

 

Résumé: Ethnies et cultes religieux dans l`Ouest de la Roumanie. Dans l`espace située dans l`Ouest de la Roumanie, au long du temps, se sont assis des populations appartenant aux nationalités diverses: Roumains, Hongrois, Slovaques Allemands, Tsiganes, Juifs. Leur poids, dans la structure de la population de cette partie du pays, a connu seulement des petites fluctuations. L`Eglise, comme l’institution, a eu un rôle très importants dans le maintient de l`être nationale de ces ethnies. Ainsi, il faut préciser la liaison directe et réciproque qui existe entre nationalité et confession. 


 

TRANSFORMĂRI ÎN FUNCŢIONALITATEA SISTEMULUI DE AŞEZĂRI RURALE DIN DEPRESIUNEA HAŢEGULUI DUPĂ 1989

Nicolae POPA

 

Résumé: Transformations dans la fonctionnalité du système des villages de la Dépression du Haţeg, après 1989. Située dans une région relativement isolée par des montagnes, la Dépression du Haţeg a enregistré une évolution pulsateur, avec des étapes de progrès et d`autre de relatif déclin. Les transformations induites par le début, en 1990, du processus de transition vers l`économie de marche visent la réalisation d`un nouvel équilibre entre les grandes secteurs de l`économie rural, cet équilibre, très instable à ce moment-ci, s`est fini avec l`accroissement relatif de la population occupée dans les  activités industrielles, sur le fond général du décroissement de la population rurale et surtout de la population occupée. Cette manque de vitalité et le retour vers l`agriculture traditionnelle posent de sérieuses problèmes aux perspectives du système rural de la Dépression du Haţeg.


 

ASUPRA AŞEZĂRII ŞI DEZVOLTĂRII TERITORIALE A ORAŞULUI CONSTANŢA

Benone Zotta

 

Abstract: On the settlement and the territorial development of the Constanţa City. Constanza city, fully using favourable natural conditions is developing on a calciferous promontory which is advancing into the sea with about 1500 m. Considering the relief and its special functions in the small gulf made by this half isle to the south, have been sheltered the first sea boats, the territorial evolution of Constanza it has a series of characteristic aspects. The city and the port are extending in separate directions but in a closely functional dependence. The port, strongly connected with the configuration of the shore, is moving to the south; the city is broadening much its borders to the north, west and south – west, the other directions of extension being limited by the sea or by the port’s prolonging.   


 

ROLUL INDUSTRIEI ÎN ORGANIZAREA SPAŢIULUI GEOGRAFIC

Claudia POPESCU

 

Rezumat: Rolul industriei în organizarea spaţiului geografic. Industria ca opţiune de dezvoltare a dominat economiile naţionale în decursul ultimului secol. Ea se manifestă în spaţiul geografic sub diferite forme şi cu diferite intensităţi în fucţie de nivelul de dezvoltare la care a ajuns societatea umană, de specificul orânduirii sociale, de forţa economiilor naţionale. Din punct de vedere geografic, industria este un element prin care se organizează spaţiul geografic, o investiţie prin care societatea umană încearcă să-i sporească eficienţa economico socială fără însă a perturba relaţiile dintre celelalte componente sau a distruge structurile interne fundamentale. Analizat prin această prismă, raportul dintre industrie şi organizarea spaţiului trebuie conceput ca unul constructiv şi stimulator şi nu ca unul incompatibil, cu excluderi reciproce. Experienţa acumulată până acum în echilibrarea acestui raport arată că, uneori, societatea umană se dovedeşte incapabilă să controleze entropia negativă provocată de impactul industriei asupra spaţiului. Deci, principala condiţie a armonizării acestei relaţii este aceea a dimensionării corecte a industriei, a analizei capacităţii de integrare a noilor relaţii impuse de acţiunea activităţilor industriale, a depistării limitelor acestora pentru evitarea unor crize disfuncţionale în spaţiul geografic. Industria este un termen generic care include pe cel de industrializare referindu-se doar la procesul de difuzie în timp şi spaţiu a activităţilor industriale. La rândul lor, aceasta reprezintă elementele prin care industria se materializează în domeniul realului. Exteriorizarea activităţilor industriale în formă abstractă determină funcţiile industriale.   


 

COMPARTIMENTUL SPAŢIAL AL STRUCTURILOR INDUSTRIALE SOCIALISTE ÎN CONTEXTUL TRANZIŢIEI SISTEMULUI  INDUSTRIAL ROMÂNESC

Octavian GROZA

 

Résumé: Le compartiment spatial des structures industrielles socialistes dans le contexte de la transition du système industriel roumain. Le démantèlement du système économique socialiste est un processus complexe, qui engendre des puissants changements de l’organisation de l’espace géographique. Ces changements sont pénibles car la résistance des anciennes structures est fort manifestée. L`article se propose d`étudier le comportement des structures industrielles socialistes face à l`avancement de la propriété prive dans le secteur industriel. La méthode employée pour saisir les structures industrielles est la classification ascendante hiérarchique. Afin de mesurer l`action des structures ainsi, on utilise l`analyse de corrélation - régression.             


 

IMPLICAŢIA TRANSPORTURILOR ŞI CĂILOR DE COMUNICAŢIE ÎN DESFĂŞURAREA ACTIVITĂŢILOR ÎN MUNICIPIUL CLUJ NAPOCA

Marin ILIEŞ

 

Abstract: The implication of transport network in the activities of Cluj Napoca town. This work analyses the impact of means of transport and ways of communication on: the environmental stage, population health and the effect on the travelling speed in the interior city. It is also a solution exposition concerning these problems, taking into consideration the explosion of vehicles after the year 1989. Therefore, a frequent problem in developed countries is turning up in Romania, too. We think that is very useful a study over a concrete situation: Cluj Napoca city.    


 

ZONA MINIERĂ MOLDOVA NOUĂ

Costela Iordache

                

Résumé: La zone minière de Moldova Nouă. L`ouvrage est axé sur les problèmes suivantes : positions géographique, brève historique de l`exploitation du gisement, géologie de la zone, contenu minéralogique, réserves et production. La zone minière est située au Sud- Ouest du Banat et constitue une ancienne région de l`exploitation des minerais de cuivre. L`exploitation a été réalisée par intermittence de la cause des conditions historiques et économiques. La géologie de la région et du gisement est très complexe, et le contenu minéralogique atteste la présence dominante de la chalcopyrite dans toutes les aires. Les réserves sont estimées a 40 ans (pour les exploitations souterraines) – et a 65 ans (pour celles de la carrière).          


 

REGIUNI TRANSFRONTALIERE ÎN EUROPA

Résumé: Régions transfrontalières en Europe. Parmi les préoccupations les plus récentes de la géographie régionale, une place primordiale revient à la question des régions transfrontalière, de la cause des implications sociales, économiques et politiques. La région transfrontalière est un espace aux particularités géographiques semblables, non seulement du point de vue physique, mais surtout du point de vue économique et social, mais divisé par les frontières géopolitiques des Etats. Le résultat: une fausse perception de l`espace, d`ou les problèmes complexes que les populations vont résoudre afin de réaliser le rêve de l`Europe: la maison européenne.     


 

some geographical problems concerning the buziaş watering place

Silviu TRUŢI, Remus CREŢAN

 

Rezumat: Probleme geografice privind staţiunea balneoclimaterică Buziaş. Zăcământul hidromineral carbogazos Buziaş este reprezentat printr-un acvifer freatic, un acvifer ascendent şi un acvifer artezian, localizate în strate de nisipuri şi separate prin strate impermeabile şi semipermeabile de argile şi argile nisipoase în cadrul formaţiunilor panonice care sunt depuse transversal pe un fundament cristalin. Acest fundament este tăiat de un sistem de falii, de-a lungul cărora s-au produs intruziuni eruptive, urmate de actualele manifestări post vulcanice de dioxid de carbon mofetic. În ascensiunea sa din formaţiunile sedimentare (panonice) panoniene, CO2 mofetic impregnează apele subterane, interceptate succesiv în acviferul artezian, în acviferul ascensional şi în cel freatic, pe o zonă relativ restrânsă de pe teritoriul localităţii Buziaş  


 

MODIFICĂRI PRIVIND STRUCTURA ŞI TIPUL DE PROPRIETATE ASUPRA TERENURILOR AGRICOLE DIN JUDEŢUL BIHOR ÎNTRE ANII 1970 ŞI 1994

Alexandru ILIEŞ

 

Résumé: Modifications dans la structure et le type de propriété sur les terrains agricoles du département de Bihor (1970 – 1994). Dans le département de Bihor on remarque la domination des terrains arables, puis les pâturages, les vignobles et les vergers. Comparativement avec 1970, en 1994 il y a une augmentation des toutes surfaces, exceptent les vignobles qui out connu une légère diminution. Jusqu’à 1989, la plus grandes parties des terrains appartenaient à l`Etat (90,0%), mai en 1994 on constante l`inversion de la situation: 6,84% sont en propriété prive, seulement les pâturages appartiennent encore à l`Etat (89,7%), dans le domaine prive 95,0%, et les vergers 60,0%.
