摘　　要：SWAT模型采用与特定的GIS软件集成的方式,可利用GIS软件辅助完成空间离散单元划分、数据组织及运行参数调整,使其难以有效地集成到不同应用的流域管理系统中。该文分析了SWAT模型运行的空间离散单元组织和输入文件结构,提出通用输入文件定制的模型集成方案。利用动态链接库技术在Visual Studio.NET环境下用C#语言开发了一套SWAT模型输入文件定制的类库和输入模型参数调整的功能模块,并通过实例进行了验证。该方法实现了将SWAT模型高效集成到不同的应用系统中而无需集成相关的GIS处理系统。The current version of SWAT model normally operates as an extension within a certain GIS frame and thus it is difficult to be integrated separately into other application system.The organization of spatial discretization units and configuration of input data for SWAT model were analyzed in detail in this paper.A general integrated frame for SWAT model was farther put forward based on customization of input data.The class libraries of input data files and parameter adjustment module for running SWAT model were developed under the Visual Studio.NET developing environment by using C# program language and Dynamic Link Library（DLL） technology.The integrated frame was also validated by using the modeling case study in Lianshui Basin,Xingguo County.By using this method,SWAT model can be embedded effectively in different application system without integration with any GIS modeling environment.
