A homérsékletileg lehetséges vegetacios periodus Magyarorszagon (La période de végétation limitée par les conditions thermiques en Hongrie)
Géographie de l'Europe ; Hongrie ; Période de végétation ; Température ; Végétation
Three periods can be divided in Hungary : 1) from the basic temperature of a given plant to the overstepping of 15 oC (warming-up period)| 2) from spring overstep of 15 oC to the autumn overstep (warm period of vegetation time) : 3) from overstep
of 15 oC to that of basic temperature of the plant (cooling-down period). - (DLO)
How the systems of local administrative units were formed in four different periods in Japan in Languages, paradigms and schools in geography.
Three aspects are pointed out from the formation of the systems of local administrative units in four periods of Japanese history. The period when the statute called ritsu-ryo was established, the period when medieval fiefs were established
, the period when land surveying was enforced all over the country, the first half of the Meiji period. - (SGA)
Behaviour of beach profiles during accretion and erosion dominated periods
The aim of this paper is to evaluate subaerial beach profile shapes from Moruya to determine the morphological characteristics of beach and associated foredune profiles in each of two periods recognized from a previous study : the accretion
-dominated period (or ADP) and the erosion-dominated period (or EDP)
En simplifiant une procédure d'allocation dans le temps à un modèle à deux périodes, on ne tient pas compte de l'inégale relation entre les périodes ni de l'aggravation de la rareté des ressources disponibles au fil des périodes. L'A. envisage le
Vyskyt srazkovych a bezsrazkovych period v ceskoslovenské casti povodi Odry. (The occurence of rainy and rainless periods in the Czechoslovak part of the Odra river Basin)
The frequency of occurence of rainy and rainless periods in 23stations was analysed on the basis of continuous precipitation series from 1951-1970. (MS).
Two periods of Vistulian aeolian activity are recognized : 1) Early and Plenivistulian period of aeolian abrasion and 2) Late Vistulian period of aeolian accumulation interrupted by phases of pedogenesis. The Old Holocene period was the period
of soil-forming processes. During the Young Holocene period dune destruction occurred.

Caractérisée beaucoup plus par l'absence de rafraîchissement nocturne que par la valeur très élevée des températures maximales, la canicule de 2003 aurait en Europe une période de retour de l'ordre de 50 ans (et non 100, comme nombre d'auteurs le
Periodicita najdlhsich obdobi trvalej snehovej pokryvky na Slovensku. (Periodicity of the longest periods of parament snow cover in Slovakia)
In geographical conditions of the Slovak territory the winters are unstable. For the study of the period with permanent snow cover duration the measurements of 80 snow meter stations in the years 1921 to 1970 have been used. The differences in snow
cover duration with the same periodicity have been recorded between East and West Slovakia and between mountains and lowlands.
Greatest lake period and its palaeo-environment on the Tibetan Plateau
The greatest lake period means that the lakes are in the stage of their maximum areas. As the paleolake shorelines are widely distributed in the lake basins on the Tibetan Plateau, the lake areas during the greatest lake period may be inferred
by the last highest lake shorelines. They are several even ten times larger than that at present. The occurence of maximum areas of lakes marked the very humid period on the Plateau and was also related to the stronger summer monsoon during that period.
The AA. discuss the development of electronic atlas in China, with focus on the issues of visualization. They particularly categorise this development into 4 periods, and then analyse the characters in each period and discuss the visualization
issues. The 4 periods are highlighted : Infant period (
La période glaciaire est vivante ! - Est-elle vivante ?
Après une nouvelle définition de la période glaciaire l'A. étudie la transition entre la période libre de glace et la période glaciaire pendant le Tertiaire ainsi que l'alternance des phases froides et chaudes pendant le Quaternaire. - (D. Rouvière).
Progression de l'urbanisation en Chine à travers quatre étapes : 1949-57-période d'urbanisation active; 1958-61-période d'urbanisation très rapide; 1962-75-période de contre-urbanisation; de 1976 à nos jours-période d'urbanisation rapide
