THE GENERAL CHARACTERISTICS OF THE FLORA OF THE KARAKORUM-KUNLUN MOUNTAINS AND THE CONSERVATION, EXPLOITATION AND UTILIZATION OF THE PLANT RESOURCES
喀喇昆仑山—昆仑山植物区系的一般特征及植物资源的保护与开发利用

This paper is based on the results of the exploration during the years 1987-1988. The characteristics of the flora of the region are as follow:1.The kinds of plant are rather poor. There are only 243 genera and about 700 species belonging to advanced plants.2.134 genera (56%) belong to the temperature type. The Mediterranean and C. Asia flora elements are important elements, but they almost distribute below the altitude of 3200 m. (3800m) only.3.The Sanzhu Valley is a boundary of floristic regions. 72 genera (among total 243 genera) do not appear in the area on the east of ihe valley. This perhaps shows the climate On the east is much drier than that on the west.4.There are no strict endemic genera, but the species differentiate actively. The number of their populations is large.The medicine resources is important in this area. Rhodiola, Saussurca, Allium Hymenola-ena, etc, should be studied first and exploited rationally in the future.
