【摘要】:基于物理機(jī)制的分布式水文模型DHSVM能精細(xì)模擬中小流域水文過程,在國內(nèi)外有廣泛應(yīng)用。該模型驅(qū)動(dòng)數(shù)據(jù)制備繁雜,其河網(wǎng)數(shù)據(jù)用Arc/Info AML腳本生成,受昂貴的商業(yè)許可限制,嚴(yán)重影響DHSVM的可操作性和普及應(yīng)用。在剖析DHSVM模型中河網(wǎng)數(shù)據(jù)表達(dá)與組織的基礎(chǔ)上,采用C++和開源GIS庫實(shí)現(xiàn)了DHSVM河網(wǎng)數(shù)據(jù)的自動(dòng)制備。新方法將可執(zhí)行程序和配置信息分離,配置靈活、可控性強(qiáng),是DHSVM實(shí)現(xiàn)自動(dòng)化運(yùn)行和智能化配置的必要基礎(chǔ)。
[Abstract]:DHSVM distributed hydrological model with physical mechanism can small watershed hydrological processes simulation based on fine, has been widely used at home and abroad. The model driven data preparation is complex, with Arc/Info AML script to generate their network by expensive commercial licensing restrictions, seriously affect the operation of the DHSVM and application of DHSVM model in the analysis of river network. Based on the data expression and organization, using C++ and open source GIS library to realize the automatic preparation of DHSVM network data. A new method for the executable program and configuration information, flexible configuration, strong controllability, DHSVM is the necessary basis for automatic operation and intelligent configuration.
