本文介绍了1985年作者建立北京城市水资源系统S.D模型的主要工作内容,包括:研究的出发点、对整个系统结构及因果关系分析、流图设计、建模过程、策略设计、S.D模型所能回答的问题。 本研究系以北京市供水为对象,从一次水资源开发、工业用水、城市生活用水、农业用水、城市污水回用、污染及其防治、水经济等七个子系统的综合因果关系,进行系统分析,突出工业用水问题,所提供的原则方法可同样应用于流域水资源分析或地区性农业用水分析,可以说,本研究为水资源系统分析提供了一个包含成百个参变量的通用方法。
This paper introduces the author’s main contents of establishing the SD model of urban water resources system in Beijing in 1985, including the starting point of the research, the analysis of the whole system structure and causal relationship, the design of flow chart, the modeling process, the strategy design, the SD model can answer The problem. Based on the water supply in Beijing, this research systematically analyzes the comprehensive causality of seven subsystems including water resources development, industrial water use, urban domestic water use, agricultural water use, urban wastewater reuse, pollution and its prevention and control, and water economy. , Highlighting the problem of industrial water use, the principles and methods provided can be equally applied to basin water resources analysis or regional agricultural water use analysis. It can be said that this study provides a universal method for water resources system analysis that contains hundreds of variables.
