[Objective]Soil erosion is complex and diverse in Tibet Autonomous Region locating in the southwest of China,attributed to its special environment represented by high altitude and cold climate.Through field survey,this study aims to systematically understand the characteristics of soil erosion in densely populated areas in Central and Eastern Tibet,and to provide a basis for regional soil erosion control in the future. [Methods]The survey was conducted from August 12to 28,2018.We selected 11typical watersheds along a transect across Linzhi,Gongbujiangda,Lhasa,Qushui and Shigatse areas.We investigated and analyzed soil erosion of local primary land use types,including forest,grassland,and farmland.[Results]In the southeastern part of Tibet,continuous rainfall caused severe erosion in forest,farmland and on road slope. Small gullies appeared in the forest,collapse occurred in the cropland with ongoing developed headward erosion,while drop sill,gully,and upper-soil collapse occurred on the road slope.In the valleys of Central Tibet,gully erosion on the proluvial fan/pluvial tableland and terraces were severe.The densely distributed gullies and channels destroyed the landforms,and seriously affected local agriculture and animal husbandry. The wide valley area presented complex erosion characteristics influenced by both wind and water.[Conclusion] The soil erosion process in Tibet Autonomous Region is complex and diverse at present,and it has a high risk of accelerated erosion due to climate change and intensifying human activities.Thus,it is necessary to systematically study soil erosion process and mechanism,and urgent to enhance the soil and water conservation work in this area.Moreover,it is also important to strengthen our awareness of environmental protection to this fragile ecological environment in Tibet.All these provide the foundations for the implement of the green development conceptlucid waters and lush mountains are invaluable assetsproposed by the government of China.
