| 摘 要： | 由于地区间的CN参数差异很大,导致运用SCS模型计算降雨径流时不同使用主体的主观性太强。为了获得适合红壤地区的CN参数,利用江西省德安县燕家沟流域观测小区2001-2003年的降雨径流资料反算CN。然后通过SPSS软件对降雨量与CN参数进行回归模拟,得到不同小区的CN模拟函数。最后利用2004年的降雨径流数据对模拟结果进行检验,得到了可信度较高的结果,同时说明了SCS模型估算红壤土流域径流量的可行性。

| Abstract: | It is subjective to calculate the runoff from rainfall by soil conservation service(SCS) model due to the large differences of CN parameter among regions. In attempt to get the particularly suitable CN parameter for the red soil region, the CN parameter was calculated based on runoff and rainfall data from the observation plots of Yanjiagou watershed in De'an County of Jiangxi Province during 2001-2003. The regression analysis between rainfall and CN parameter produced the CN simulation functions for different runoff plots. The result indicated that the reliability of CN simulation functions of different runoff plots were very well. Meanwhile, it also showed the feasibility of the application of SCS model in estimating runoff volume in slope field of red soil. |
