| 摘 要： | 详细分析了基于DEM的流域水系提取,并利用全国1:25万的DEM,对浊漳河南源流域的水系提取进行了研究。结果表明,在盆地区域添加能反映微地形变化的数据点,并将河谷中出现伪河道的干流河网数字化,能生成反映流域实际情况的模拟河网。该方法为消除提取水系时平原区域出现的伪河道提供了一种新的修正方法。 |

| Abstract: | In this paper,the detailed process of the river system extracted from digital elevation model(DEM) was analyzed,and extraction of the river system of the South Zhuozhanghe watershed was done by using the data of 1:250000 DEM.The results show that the extracted river system matches well with the natural river system by means of adding the elevation data and digitizing main river with pseudo river.A new technique was developed for eliminating the pseudo river occurred in the process of extracting river system in the flat areas. |
