摘　　要：河湖水面变化是河湖生态复苏的重要表征。基于卫星遥感地表水体产品(GSW)识别华北地区5省市1984—2020年水体面积和河流连通性的时空变化特征,构建河湖水面恢复指数分析华北地区河湖水面变化过程,对华北地区河湖复苏现状进行了定量评价,可为相关地区河湖生态复苏工作开展提供参考。Rivers and lakes water surface change is an important indicator of ecological recovery of rivers and lakes.Firstly, the global surface water product(GSW) derived from landsat satellites was used to identify the temporal and spatial change of surface water area and river connectivity in five administrative districts of North China from 1984 to2020. Secondly, a rivers and lakes recovery index derived from surface water area and river connectivity was used to analyze the changing process of water surface of rivers and lakes in North China. Finally, a quantitative evaluation was carried out on the status of rives and lakes recovery in the North China. The result can provide references for the development of the ecological recovery of rivers and lakes in related regions.
