鱼梁河湿地公园土地利用和生境质量遥感监测分析

Analysis of he Land Use and Habitat Quality Using Remote Sensing Data in Yulianghe Wetland Park

利用高分卫星遥感数据,对贵州鱼梁河国家湿地公园2016—2019年土地利用和生境质量变化进行监测,定量评估分析湿地公园的生态环境质量与变化情况。结果表明:①湿地土地利用类型主要以林地、河渠和水田为主,期间林地面积增加31.46 hm 2;②湿地植被恢复良好,林地植被生态改善最为明显;③2016—2019年湿地生境质量指数上升1.78%,生态环境质量略有上升;④区域生境质量变化与土地利用类型的变化直接相关,且人为因素是土地利用类型变化主要驱动力。

Based on the GF satellite remote sensing data,the land use and habitat quality at YuLiangHe National Wetland Park in Guizhou Province from 2016 to 2019 were studied.The results show:①The types of wetland are mainly woodland,river canals and paddy fields,during which the woodland area increased by 31.46 hectares;②The wetland vegetation ecology has improved,especially the improvement of woodland;③During 2016—2019,the wetland habitat quality index increased by 1.78%,indicating the ecological quality improved slightly;④The changes of regional habitat quality are directly related to the changes in land use types,and human factors are the main driving force for changes in land use types.
