| 摘 要： | 基于云南省蒋家沟流域的DEM,根据流域地貌,利用地理信息系统软件划分流域子单元,在此基础上利用蒋家沟土地利用类型、土壤类型等地理信息数据和流域水文、气象资料,根据SCS模型CN值标准表,提出适合各子流域产流计算的CN值,绘制出了蒋家沟流域次降雨的CN值分布图,进而应用SCS产流模型和等流时线法对云南省蒋家沟流域的降雨一径流过程进行了模拟.模拟结果表明,与有限的实测资料相比较,模型的模拟精度在90%以上,模拟结果较为满意,说明基于CN值的SCS模型可以应用于蒋家沟流域,同时模拟的径流过程可以弥补实测资料的不足,为蒋家沟流域分布式水文模型的建立提供理论依据和研究方法. |

| Abstract: | Based on the DEM (digital elevation model) of Jiangjiagou watershed,Yunnan Province,the watershed is compartmentalized into some sub-units according to landform by using Geographical Information System software. With the information data of land use,soil classification,hydrology,and meteorology,the fitting CN values for sub-watersheds are presented and the CN distribution map is drawn by the GIS software. The hydrograph of calculated runoff process by the SCS model and isochrones method is fitted well with observed runoff data. It shows that SCS model can be successfully used in Jiangjiagou watershed and simulated result can supplement observed data. This paper provides a method to study the distributed hydrological model in Jiangjiagou watershed. |
