摘要
通过应用多源高分辨率遥感影像,采用自动解译与人工识别相结合的方法,定量分析永定河水系补水前后水面积和河势变化,研究结果表明补水前水面积为8.01 km^2,补水高峰水面积为26.00 km^2,补水后水面积为22.68 km^2,水面积的变化主要集中在卢沟桥拦河闸下游段。研究成果可为补水生态环境效益评估、水资源优化配置等提供重要的支撑。
Multi-source high-resolution remote sensing image was used and the method of automatic interpretation combined with artificial recognition was adopt to quantitatively analyze the change of water surface area and fluvial morphology during ecological water supplement.The result showed that the water surface area increased from 8.01 km2 to 22.68 km2,the maximum area of the ecological water supplement is 26.00 km2 and the main changing region distributed along the plain river.The research results could provide important support for ecological and environmental benefit assessment of water supplement and optimal allocation of water resources.
