Identification of landscape suitable water levels in Bosten Lake based on fuzzy membership degree distribution function
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 1 046.70 m,with a low warning water level of 1 045.00 m,a high warning water level of 1 047.90 m,and low and high damaged edge water levels of 1045.40 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 1 045.90~1 047.16 m for spring and autumn,1 046.00~1 047.00 m for summer,and 1 045.85~1 047.25 m for winter.
