组件技术与计算机技术相结合能克服传统建模方式难以解决大规模系统模拟集成的缺陷，可有效促进流域模拟模型集成的发展。为此，本文从模型组件化的可移植性、灵活性、扩展性、与第三方软件集成等方面分析了组件技术在流域模型集成中的重要作用，分析了国内外组件式流域模拟模型集成技术的发展现状，进而提出国内流域模拟模型集成系统存在的问题。最后，从数字流域模型平台化、基于云计算模式的模型集成、模型应用的组件化等方面，探讨了流域模拟模型集成系统的发展趋势。

The combination of component technology and computer technology can conquer the difficulty to make large-scale system simulation integration by the traditional modeling method and can promote effectively the development of the watershed simulation model integration. Therefore, the paper analyzed the important role of the modeling component in the portability, flexibility, expansibility and third party software integration. The present situation of watershed simulation model integrated technology at home and at broad are discussed. The existing problems at home in this research field are proposed. The paper looked forward to the development trend of watershed simulation model integrated technology in modeling platform, modeling integration-based the cloud computing and the modeling application component.
