本区土壤共分8个土类,由海拔3534m到6646m分布有潮土、风沙土、草甸土→阿嘎土→巴嘎土→黑毡土→草毡土→高山寒漠土,耕种地分布在除风沙土外的前五种土类上。因环境影响,土壤有矿化分解程度低,粗骨性强,发生层次不明显,有机质积累明显,pH值较高等特点。开发利用中存在水平低,用地结构不合理,用养脱节等现象。针对各土类特性和存在问题提出加强农田水利水电建设,植树种草培肥土壤和调整用地结构等合理改良利用措施。
The soil in this area is divided into 8 soil types, ranging from the altitude of 3534m to 6646m with the distribution of fluvo-aquic soil, aeolian sandy soil and meadow soil → Agatha soil → barga soil → black felt soil → straw felt soil → alpine desert soil, cultivated land Distribution in addition to windy soil outside the first five kinds of soil. Due to the environmental impact, the soil is characterized by low degree of mineralization and decomposition, strong coarsening, obvious occurrence of layers, obvious accumulation of organic matter, and high pH value. There is a low level of development and utilization, land use structure is unreasonable, with raising and taking off phenomenon. In view of the characteristics and existing problems of various soil types, some measures, such as strengthening water conservancy and hydropower construction in farmland, planting soil for planting trees and grass and adjusting the structure of land, are put forward.
