摘要
基于2019年云南洱源西湖国家湿地公园的土地利用矢量数据,对湿地公园的土地利用类型进行了分析,采用LDI评价方法评价了该公园的生态环境健康状况。结果表明:该湿地公园的林地面积最大,比例为42.42%,主要位于湿地公园的西侧山地,为该湿地公园重要的水源保护地;其次为水体,面积比例为27.90%;再次为农地,面积比例为13.40%。整体上湿地公园的生态环境健康水平处于“一般”等级,综合指数为2.45;从功能区的角度来看,管理服务区和合理利用区的健康水平处于“不健康”等级,其综合指数分别为6.84、5.40;保育区情况相对较好,其生态环境健康水平“健康”,综合指数为1.75。
Based on the land use vector data of Eryuan West Lake National Wetland Park in 2019,the land use types of the wetland park were analyzed,and the ecological environment health status of the park was evaluated by using the LDI evaluation method.Result shows that:1.The forest land area of Wetland Park is the largest,accounting for 42.42%,which is mainly located in the west mountain area of the wetland park,it is the important water source protection area of the Wetland Park,followed by water body,with the area proportion of 27.90%,and agricultural land with the area proportion of 13.40%;2.On the whole,the ecological environment health level of Wetland Park is in the“general”level,with the comprehensive index of 2.45,From the perspective of functional areas,the health level of management service area and rational utilization area is in the“unhealthy”level,and the comprehensive index is 6.84 and 5.40 respectively.The situation of conservation area is relatively optimal,and the comprehensive index of ecological environment health level is“healthy”,and the comprehensive index is 1.75.According to the evaluation results,some management and protection suggestions are put forward.
