Recherches sur un grand versant de l'Himalaya central (Presentation of a research about the slope system in the Himalaya)

摘要

Abstract. - A Research is undertaken on a monsoon slope of the south face of the Himalaya in central Nepal. The theme is a best knowledge of the parameters which govern the bioclimatic levels and the geomorphological processes, to study the ecosystems, including production and productivities of vegetation, and to understand the change of the agricultural system. In this paper the methodology of the climatic and gemorphological study is only presented. The first data collected since the middle of 1979 show that air and soil moisture level remains during the whole year at the station located at 2 850 m. There is a larger amount of precipitation on the cultivated terraces (1 400-2 400) than above in the oaks and fir forest.
