Using the analytic hierarchy process to identify key landscape points in Bosten Lake, based on the analysis of lake characteristic water levels, a fuzzy membership degree distribution function was constructed for the water level and landscape suitability of key landscape points, and the suitable water level range for Bosten Lake landscape in different seasons was calculated.The results indicate that lake water quality and annual tourism revenue are the main factors for identifying key landscape points in Bosten Lake.The optimal landscape water level for Bosten Lake is 1046.70 m, with a low warning water level of 1045.00 m, a high warning water level of 1047.90 m, and low and high damaged edge water levels of 1045.40 m and 1047.40 m, respectively.There are differences in the suitable water level for the landscape of Bosten Lake in different seasons. The suitable water level range is 1045.90~1047.16 m for spring and autumn, 1046.00~1047.00 m for summer, and 1045.85~1047.25 m for winter.
