采用SCS-CN水文模型和GIS确定雨水集蓄工程的位置

针对北京西部清水河上游山区生产生活用水日趋紧张的问题,该文应用遥感与地理信息系统软件处理TM影像、土壤和质地图及数字高程模型等基础数据,结合soil conservation service(SCS)曲线数法计算径流量,根据雨水集蓄工程技术规范构建了雨水集蓄工程位置选择约束集。在此基础上,运用地理信息系统软件对坡度、径流潜力及集水路径的空间及属性数据进行叠加和邻域分析,得到适宜的雨水集蓄工程位置。主要结果如下:适宜修建蓄水坑塘的面积4.24km2、蓄水池位置46处、拦水坝位置50处、大口井位置53处、适宜庭院集雨区的面积4.95km2。结果可为合理开发利用雨水资源及工程建设提供理论支撑和科学指...

Summary:针对北京西部清水河上游山区生产生活用水日趋紧张的问题,该文应用遥感与地理信息系统软件处理TM影像、土壤和质地图及数字高程模型等基础数据,结合soil conservation service(SCS)曲线数法计算径流量,根据雨水集蓄工程技术规范构建了雨水集蓄工程位置选择约束集。在此基础上,运用地理信息系统软件对坡度、径流潜力及集水路径的空间及属性数据进行叠加和邻域分析,得到适宜的雨水集蓄工程位置。主要结果如下:适宜修建蓄水坑塘的面积4.24km2、蓄水池位置46处、拦水坝位置50处、大口井位置53处、适宜庭院集雨区的面积4.95km2。结果可为合理开发利用雨水资源及工程建设提供理论支撑和科学指导。

Water shortage in mountainous areas is a prevailing problem in Northern China. In this study, the upstream of Qinghe River, a semiarid mountainous area in western Beijing, was investigated and relevant solutions were put forward. The Remote Sensing (Erdas imagine 9.1) and Geographic Information Systems (ArcGIS 10) software were adopted to process data about TM images, soil texture map and Digital Elevation Model (DEM). Soil Conservation Service curve number (SCS-CN) method was used to calculate runoff and establishe constraint site selecti
