Zonation of flora and vegetation of the northern declivity of the Karakoram/Kunlun mountains (SW Xinjiang China)
Botanical results of the « Sino-German Joint Expedition to K2, 1986 » are presented with remarks on vegetation of SW Kashgaria, the W Kunlun Shan and the N declivity of the central Karakoram mountains. The vertical and horizontal zonation
of the vegetation and flora of a cross-section of the Karakoram/Kunlun N declivity from the edge of the Tarim basin to the summit-pyramid of K2 is outlined. An annotated list of 301 species collected is given. Floristical and vegetation features of the Karakoram
/Kunlun N declivity are discussed in connection with environmental factors and their variation, and in relation to pleistocene glaciation.

Favourable population climate has lasted. Both absolute number of delivered children and reproduction rate have declived but in very slow way. The total fertility rate (2,328) and the net reprodcution rate (1,108) belonged to the most favourable
of the southern declivity of the Easten Hymalayas from paddy rice cultivation in the valleys to various maize-millet combinations, field-pasture shifting cultivation land and grazing land at the subalpine level. The A. studies the influence of human impact
The erosion of soils is becoming a serious problem in forested mountain areas where the natural and anthropogenic influences are favourable to this process. (Flysch substratum, heavy rainfalls, declivity of slopes, tractors and other machines
