摘　　要：水土流失是制约藏东山区农牧业发展的主要因素,高山高寒区的水土流失治理模式研究不仅能够解决生活生产的实际需求,也能够丰富水土流失科学研究。以野外调查藏东地区典型小流域的主要水土流失特征入手,结合遥感分析当地土地利用,土壤和植被特征,提出了适用于研究区的5种治理模式:草地冲沟侵蚀区治理模式,水蚀和冻融交错侵蚀区治理模式,坡耕地面状侵蚀区治理模式,沟道侵蚀区治理模式,林—灌—耕地交错区综合治理模式。Soil and water loss was the restrictive factor of the farming and animal husbandry development in the Eastern Tibet.The study on the soil and water loss control model of the alpine and cold region was not only the requirement of local livelihood and production,but also the scientific demand of the soil and water loss research.According to the main soil and water loss characteristics of the typical watershed in the Eastern Tibet by the filed investigation,five kinds of soil and water control models were suggested under the investigation on the local land use,soil type and vegetation through the remote sensing analysis.These models were the control model of gully erosion on the grassland,the control model of erosion in the wind-water interaction zone,the control model of sheet erosion on the slope farmland,the control model of channel erosion and the integrative control model of the interaction zone between forest-shrub land and farmland.
