中文摘要：

中间件是近10几年来发展起来的软件技术，由于具有可成长性、适应性、可管理性、高可信性等特点，使其在网络通信、信息处理、数据管理与维护等方面发展迅速，并在诸多工程领域有着广阔的应用前景．中间件技术与水利工程管理系统相结合，为水利工程管理的多系统、多数据源的复杂决策问题提供切实有效的处理方法，并能有效地提高各级水利建设工程管理部门的工作效率、工作质量和工作水平．结合水利行业的特点，在分析水利工程管理系统的中间件以及基于中间件技术的水利工程管理支持系统结构的基础上，对系统实现所必需的异构数据集成、面向应用集成的信息门户与服务平台、系统开发框架以及应用组件服务平台等关键技术和实现途径进行了分析与研究，为开发基于中间件技术的水利工程管理信息化系统提供了技术支持．

英文摘要：

The middleware is a software technology, which been developing for more than ten years. Because of having remarkable advantages in applications （such as expansibility, adaptability, manageability and high creditability）, it develops rapidly and has widely application prospect in many engineering fields, network communication, information processing, data management and maintenance etc. The combination of middleware technology with water resource project management system is an innovation and a skip development on water conservancy informationization application field. It provides effective processing method for complicated problems decision - making with many systems and data - resource of water conservancy project management. Considering the characteristic of water industry, in the paper, the water conservancy project management supporting system was developed. The key technologies and realization approaches of system, such as heterogeneous data integration, information portal facing integrated application, development framework of sestem and service platform of application component were analyzed and investigated, based on the analysis of supporting system structure and middleware technology in the water conservancy project management. It offers a powerful technology support for the informationization construction of water conservancy project management.
