Abstract: Jingpo Lake is the largest mountain barrier lake in China and the second largest lake of this kind in the world. It is a typical river connected deep-water lake with special topography and landform. Jingpo Lake and its surrounding eco-environment were investigated, and the types and widths of littoral zone and buffer zone were classified. Based on the topographic and landform characteristics and hydrological conditions of Jingpo Lake shore zone, the littoral zone of Jingpo Lake was divided into six types including hill type, dike type, road type, estuary type, village type and farmland type, while the buffer zone of Jingpo Lake was divided into three types including village type, farmland type and village type. Additionally, based on the factors such as habitat, land use mode, soil erosion and vegetation distribution of the littoral zone and buffer zone, the main problems of eco-environment in the littoral zone and buffer zone of Jingpo Lake were discussed and the ecological restoration ideas of Jingpo Lake littoral zone and buffer zone were proposed. The results were aimed to provide reference for the ecological protection and restoration of the littoral zone and buffer zone in Jingpo Lake.
