陆面水量～水质～生态耦合系统模型研究

本文在实践的基础上, 提出了“多箱模型方法”(Multi-Box Modeling)以建立陆面水量～水质～生态耦合系统模型. 该方法是基于单元模型思想, 利用计算机强大运算功能, 采用多单元耦合, 水量、水质、生态系统子模型耦合来建立模型. 其特点是, 在空间上是不同“计算单元”(箱体)的耦合; 在考虑因素上又是水量、水质、生态量化指标的耦合. 经实例验证, 该模型可靠, 计算方法简单, 能应用于生产实际.

Study on the modeling method of water quantity-water quality-ecology coupling sytem

A multi-box modeling method is proposed to establish the quantitative model which coupling the variation of water quantity, water quantity and ecology in sustainable management of water resources. The area to the studied is divided into some elements (boxes) and the exchanges of water flow, water quality and relevant material among the boxes are possible. The quantity-quality-ecology system model for each box can be established individually. On the basis of mass conservation principle the integrated couplings of the boxes are calculated according to the certain procedure and eriterion. The method is successfully applied to the water resources managment of three river basins.
