潮汐河网区环境管理决策支持系统开发与应用研究

Development of environmental decision support system for tidal river networks and its application to the Pearl River Delta

本文介绍的是一个适用于潮汐河网区水环境管理和决策的软件系统 (EDSS) ,其主要功能是协助政府部门进行有效、科学的水环境管理。该系统采用了地理信息系统、数据库管理系统、模型库管理系统和专家系统等先进技术 ,有助于提高复杂潮汐河网地区的水环境管理和决策水平。本文首先介绍了 EDSS的结构、设计思想和新颖的实现技术 ,然后讨论了 EDSS的应用领域和未来的研究方向。

WT5”BZ]The environmental decision support system (EDSS) was developed as the outcome of a collaborative research program which had the objective of developing a comprehensive, easy to use decision suppot system for water pollution control in tidal river networks in general and for that in the Pearl River Delta in particular. Its purpose was to provide a practical tool which could assist government agencies in decision making for the efficient management of water resources in terms of both quantity and quality. By combining the capabilities of geographical information system (GIS), database management system(DBMS), model management system(MMS), optimization procedure and expert system, the quality of decision making was thus improved in an area which has the most complicated tidal river network patterns as well as the fastest economic development in the world. This paper outlines the basic concepts and philosophy adopted in developing the EDSS. Thereafter, the system architecture, design features, implementation techniques and major facilities provided are described briefly. Finally, potential applications of the system and directions for further research are also outlined. [WT5HZ]
