The southeast Qinghai-Xizang (Tibetan) Plateau is a physical region with optimum hydrothermal conditions, alpine soils and most types of Chinese forest soils. At present, partial soil resources are being damaged and the mountain ecology also tends
to be instable. So rational cutting and forest conservation, barren mountain afforestation, returning the cultivated land on steep slopes to forest, controlled grazing, and soil amelioration constitute important means for rational use of soil resources
