摘要
本文介绍了分布式水文模型EasyDHM模型的软件系统MWEasyDHM,主要由4个部分组成:(1)面向水文分析的通用GIS软件;(2)前处理模块;(3)模拟模块;(4)后处理模块。其中面向水文分析的通用GIS软件以开源GIS软件MapWindow为基础开发,并包括了其他模块所涉及的基本GIS功能;前处理模块包括基于DEM的水文分析组件,模型参数推求模块和降水量、气象数据插值模块;模拟模块提供了实时计算功能,能实时查看模拟结果;模型后处理模块包括了模型参数自动识别、运算结果统计分析及以表格、图表等方式对模拟结果的展示。MWEasyDHM的开发解决了分布式水文模型快速建模及率定的难题,并为将来升级开发及大范围推广应用奠定了基础。
This paper introduces a distributed hydrological model system, MWEasyDHM, which consists of four main parts： （1） general GIS tool for hydrological analysis, （2） pre-processing module for modeling, （3） simulation module and （4） post-processing module. The general GIS tool for hydrological analysis has been developed on the basis of MapWindow GIS, which is open-source. This GIS tool also includes func- tions for other parts of this system. The pre-proeessing module is made up of three sub-modules： sub-mod- ule for hydrological analysis based on DEM, sub-module for model parameter calculation, and sub-module for interpolation of meteorological and rain data. The simulation module supplies the function of real-time simulation, i.e. results can be shown in accordance with simulations. The post-processing module includes two sub-modules： auto-calibration of parameters, and the display of simulation results. Overall, The MWEa- syDHM has solved the problem for fast modeling and calibration of the EasyDHM model, and provides a good foundation for further development and applications of distributed hydrological simulations in large scales.
