| 摘 要： | 为掌握甘肃省河流特征与径流及水文现象之间的关系,根据Horton理论,运用地理信息技术对境内河流进行4级划分、特征定性分析及定量计算。结果表明,河道等级与相应面积序列等级服从有序性表现,河流的平均宽度和形状系数也有明显的地域和区域特性。

| Abstract: | In order to get the river characteristics and relationship between the runoff and other hydrological factors in Gansu Province,based on Horton theory,GIS was used to classify the rivers by 4 levels,make characteristic qualitative analysis and quantitative calculation.The results show that river levels and the corresponding area sequence level performance in order.River average width and river shape coefficients have obvious local characteristics. |
