| 摘 要： | SCS模型考虑了径流与土壤特性和土地利用情况的关系,能反映不同土壤和地面覆盖条件影响产流的特点,所需参数较少,是一种简洁且实用的流域径流计算方法。以福建省敖江一子流域为例,在ArcView环境中应用SCS模型,利用GIS技术确定和反映不同土地利用类型的CN值和径流量,并使这些值建立在空间数据之上,同时以地图的形式显示,实现径流数据与空间数据相结合,以直观的方式为流域管理决策者服务。

| Abstract: | SCS model is a terse and applied runoff calculation method for watershed,which can consider the relations between the runoff,soil property and land use.It can reflect characteristics of flow producing influence by different soil and land cover,and require less parameter.A sub-basin of Aojiang River in Fujian Province is taken as an example by using SCS model in ArcView environment.With GIS technology,CN values and runoff of different land use patterns can be determined and confirmed.The values are based on the spatial data,and showed in the form of maps.All operations,including input,calculation and display,are operated in ArcView,which fulfills the combination of runoff data and spatial data to serve watershed governors and policymakers in a visual way. |
