山洪风险分析系统由洪水风险分析、易损性分析以及洪水风险图成图等功能组成。系统基于.NET Framework平台开发，而现有的水文模型采用Fortran 95语言编写。针对.NET Framework平台不支持Fortran语言的情况，采用动态链接库（DLL）的方法实现了系统与现有水文模型的集成。重点解决了Fortran语言与.NET Framework交互时遇到的堆栈管理约定、命名约定及参数传递约定等问题，并通过湖北省厦铺河流域洪水风险分析案例对山丘区洪水风险分析系统进行了检验，证实了系统的可靠性。%The flash flood risk analysis system includes the functions of flood risk analysis, vulnerability analysis and flood risk mapping. The system development is based on .NET Framework platform and the hydrological model is written in Fortran 95. Because the .NET Framework platform does not support Fortran language, dynamic link library (DLL) is used to achieve the integration of the system with existing hydrological models. The study focuses on solving the problems of stack management agreement, naming convention agreement and parameter passing agreement in combining Fortran language with .NET Framework. A case of flash flood analysis in Xiapu River basin, Hubei Province is used to test the system, and the results confirm the reliability of the system.
