Abstract: SCS monthly wa ter balance model，which based on SCS hydrologic model，Was used to simulate the monthly runof of 27 sub-basins in the Dongjiang,Ganjiang,Hanjiang and Yellow River basin．It Was found that：a)the runof simulation results are relatively satisfactory；b)the values of three parameters are steady；C)the applicability of the model is stronger and it call be applied in humid，semi-humid and arid area；d)the structure of the model is simple and only has three parameters．Finally,a scheme that takes advantage ofremote sensing techniques and GIS powerful management capability are discussed and prospected．

Key words: water resources, climate change, monthly water balance model, SCS model

摘要： 应用以SCS水文模式为基础的月水量平衡模型，模拟东江、赣江、汉江和黄河中游的27个子流域的径流、 结果表明精度较高，参数值稳定，模型具有较好的适应能力，能够应用于湿润、半湿润、半干旱地区，而模型仅 有3个参数，使用简单．最后提出结合遥感与地理信息技术改进模型的思路，
