采用模块化设计思想 ,构建了水环境保护与经济发展的决策模型 ,主要模型有水资源需求模型、水环境容量模型、宏观经济模型、水污染控制模型、经济结构优化模型等。通过对多级模型的求解 ,获得既符合经济发展目标 ,又满足环境保护要求的合理的经济结构和合适的发展速度。从而为水资源保护与经济发展的研究提供可借鉴的思路和方法。

The decision making model of water environmental protection and economic development was proposed by means of modularization design idea.This model mainly consists of water demand module,water environmental capacity module,macro economy module,water pollution control module and economic structure optimization module.With a multilevel model,by solving equations representing each of these components,the rational economic structures and appropriate development speed,which either accord with economic development aim or meet water environmental protection needs,were achieved.It provides a trajectory and method for the study of water environmental protection and economic development.
