选择1979-2016年间多时期、多类型、多光谱遥感数据,分析评价洞庭湖区内湖近40年的面积变化.结果表明,最近40年洞庭湖区内湖面积保持相对稳定,丰水期间呈上升趋势,枯水期间波动下降,2016年内湖总面积比1980s初减少3.94%.随着湖泊面积增加,湖泊水面面积变化的比例和幅度逐渐减小,大型湖泊(>10 km~2)和中型湖泊(5~ 10 km~2)面积相对稳定,小型内湖(

In Lake Dongting district, there are some inner lakes located at low-lying fields surrounded by protective embankments. As a result of the dual effects of climate change and human activities, the area of inner lakes had changed apparently over the past decades. In this study, changes of water surface area for inner lakes in Lake Dongting district had been surveyed, using multi-time remote sensing images from 1979 to 2016. The total area was relatively stable, while a rising trend in wet season and decreased in a fluctuation way during dry seaso...
