水循环模拟系统(Hydro Informatic Modeling System,简称HIMS)的开发已为水循环模拟提供了综合的模拟工具.本文为扩展HIMS系统的应用,紧密集成RS/GIS技术,自主开发了生态水文模拟系统(Ecohydrological Assessment Tool,简称EcoHAT),对生态水文过程进行模拟.该系统以基本的生态水文过程为基础,集成了参数管理、RS参数反演、模型定制工具、GIS分析等工具,实现了区域尺度的分布式生态水文模拟,为水资源可持续利用提供了新的思路.通过EcoHAT在我国黄河流域典型地区、贵州酸沉降地区及北京官厅水库库岸带等地区的应用,表明EcoHAT系统能有效模拟和分析区域生态水文过程,为流域水资源综合管理提供技术支撑.
The development of the Hydro Informatic Modeling System (HIMS) has provided a comprehensive simulation tool for water cycle simulation.This paper developed the Hydrological Simulation System (Ecohydrological Assessment System) for the expansion of the application of HIMS system, the close integration of RS / GIS technology, (EcoHAT) is used to simulate the eco-hydrological process.The system is based on the basic eco-hydrological process and integrates tools such as parameter management, RS parameter inversion, model customization tools and GIS analysis to achieve a distributed Eco-hydrology simulation provides a new idea for the sustainable utilization of water resources.The application of EcoHAT in typical areas of the Yellow River basin in China, acid deposition areas in Guizhou and Guanting reservoir bank in Beijing shows that EcoHAT system can effectively simulate and analyze the area Ecological hydrological process, providing technical support for the integrated management of water resources in the basin.
