采用遥感技术提取了北京市潮白河流域2011—2015年各类水体面积,分析了该流域水体面积的年际变化和年内变化。结果表明:北京市潮白河流域水体面积呈现缓慢增加趋势;在各类水体中,水库与湖泊的水体面积年际变化幅度小,河流与坑塘的水体面积年际变化幅度大,说明北京市潮白河流域水生态环境正在改善,这些监测数据将为该流域水资源动态管理、水生态环境动态管理提供支撑。
Using remote sensing technology, the area of various types of water in Chaobaihe River Basin in Beijing from 2011 to 2015 was extracted, and the interannual and annual variation of water area in the basin was analyzed. The results show that the water area of Chaobai River in Beijing shows a slowly increasing trend. Among all types of water bodies, the interannual variation of water area of reservoirs and lakes is small, and the inter-annual variation of water area in rivers and pit ponds is large, indicating that the tide of Beijing The aquatic ecological environment in the Baihe River Basin is improving. These monitoring data will provide support to the dynamic management of water resources and the dynamic management of aquatic ecological environment in this basin.
