摘要
采用层次分析法识别博斯腾湖景观关键点,基于湖泊特征水位分析,构建了景观关键点水位和景观适宜度的模糊隶属度分布函数,计算了不同季节博斯腾湖景观适宜水位范围.结果表明:湖泊水质、年旅游业收益是识别博斯腾湖景观关键点的主要因素;博斯腾湖最佳景观水位为1046.70m,低警戒水位为1 045.00 m,高警戒水位为1 047.90 m,低、高破坏边缘水位分别为1 045.40 m和1047.40 m;不同季节博斯腾湖景观适宜水位存在差异,春季和秋季景观适宜水位范围为 1045.90～1047.16 m,夏季为 1 046.00～1047.00 m,冬季为 1045.85～1 047.25 m.
Abstract
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.
