中文摘要：

大规模的人类活动已经将不同流域连接为一个整体系统，针对跨流域复杂水问题的研究，从科研和管理的角度，迫切需要发展集多源数据集成、水循环过程模拟和决策支撑为一体的水系统综合管理与模拟平台。本文面向国家需求，采用面向对象设计方法，基于GIS平台创建了具有自主知识产权的WIM（Water system Integrated Modeling and Management Tool）系统。WIM是一个基于模块化结构的水系统综合管理与模拟工具，实现了水循环多源数据集成和多过程耦合模拟，具有数据动态加载、模型在线耦合和模块按需定制等功能。WIM提出为复杂水问题的研究，跨流域调水对陆地水循环影响与水安全分析提供了支撑，促进了中国在水循环综合模拟与系统集成等方面的科技发展。

英文摘要：

Referring extensively to domestic and foreign related construction method of the hydrologic cycle model system, with the results of CAS Knowledge Innovation Program key projects, ＂ Trans-basin water transfer and its impact on terrestrial water cycle and water safety＂, using object-oriented design methods, and based on GIS, VR and other technology, this paper tried to build a prototype system, Water system Integrated Modeling and Management Tool （WIM）, integrating data management of water resources, hydrologic cycle cou- pled models, as well as virtual reality and scenario analysis functions. WIM provides a flexible and scalable inte- grated mode for data, models and other tools and achieves the dynamic loading of data, on-line coupling of mod- els and modules, to meet the needs of management of water resources and water security analysis under different scale hydrologic cycles.
