Vegetation in this area is featured by vertical distribution and zonation, owning to the complicated terrain and physiognomy, and the variant climates in this area. Land cover is also much diversified. Ninety-five percent of this basin is mountainous area. Eighty-three percent of the people in this area are minority people (totally 18 minorities) stereoscopically scattering in the mountains. Hitherto, land is their main resource of subsistence and production. Different minority land use traditions have made a diversification in the land use pattern.
