流域可持续发展决策支持系统的建设及应用

在流域可持续发展研究中，决策支持系统建设对于快速、准确、全面和不断地获取所需信息并及时处理这些信息，提高研究和决策水平具有重要作用。流域可持续发展决策支持系统（ＶＳＤＤＳＳ） 建立应遵循系统性、有效性、实用性、通用性、可扩充性、界面友好等基本原则。ＶＳＤＤＳＳ 由数据查询检索、辅助决策支持及图形管理三个基本模块组成，每个模块都由若干子系统支持，各模块之间通过数据采集和转换系统进行联系和通讯。ＶＳＤＤＳＳ具有存储和处理多种形式的经济、资源、环境信息，进行经济、资源、环境信息的查询检索和更新，实现经济、资源、环境综合分析评价，实现流域经济、资源、环境信息的科学管理和全社会共享，提供流域发展规划及决策方案咨询，对经济、资源、环境进行动态监测等多种功能。

THE CONSTRUCTION AND APPLICATION OF THE VALLEY SUSTAINABLE DEVELOPMENT DECISION SUPPORT SYSTEM

In the study of the Sustainable Development of the Valley, the Decision Support System is one important method that could help us getting data rapidly, correctly, all-sidedly, continuously, and dealing with it in time, And it is also important in raising the level of the study and decision. The construction of the Valley Sustainable Development Decision Support System (VSDDSS) must obey such fundamental rules as systematic, Validity, practicability, versatility, expandability, interfacial friendly etc. VSDDSS is composed of three elemental modules: data query and access, ancillary decision support and graphics management. Each module is base on several subsystems, the interconnection and communication between the modules is finished by the system of data picking and transformation subsystem. the database of economy, resource and environment is an important part of VSDDSS, it has the feature as following: (1)The data is unified and regular; (2)The user can combine the data freely; (3)The absence data is dealing with by speak with user; (4)The method is selected by data; VSDDSS has the function that the information of the economy, resources and environment can be looked up, accessed and updated, the synthesis analysis and evaluation can be realized, the information of the economy, resources and environment of the Valley is managed scientifically and shared by the whole society, and that the development plan and decision scheme consultation can be provided.
