| 摘 要： | 基于Arc GIS 10.0、Excel及数字高程模型,分析元江县县域内水文特征,提取区域内主要干流及支流进行可视化,计算河流信息,并基于县域进行水文模拟。结果表明:元江县水域单一,明显水域只有元江流域在元江县内的部分;除自然降水外,元江县水源不丰富,区域地表破碎度较小。县域水文分析能为将来水利发展和城市规划提供参考。

| Abstract: | Hydrological features in Yuanjiang County were analyzed based on ArcGIS10.0, Excel and Digital Elevation Model.The main stream and tributary were extracted to realize visualization and to calculate river information.Hydrological simulation was carried out based on county region.Results showed that Yuanjiang County had single water area.Except natural precipitation, water resource was not abundant in Yuanjiang County;fragmentation of regional surface was relatively small.County hydrological analysis provided references for the water conser-vancy development and urban planning in future. |
