区域水资源配置系统网络图

本文分析了国内外水资源系统网络图的元素组成、系统构成、存在的不足和研究进展,总结了水资源配置的主要特点,提出绘制水资源系统网络图的基础是水量平衡原理、水资源天然和人工侧支循环演化二元模式、多水源联合调配、经济与生态和谐发展等方面。针对水资源配置供需平衡分析和耗水平衡分析,将经济、生态环境、水资源系统简化和抽象为节点、计算单元水传输系统、流域单元水传输系统三类元素,详细论述了构成系统网络图的基本原理,各类元素的构成、功能、简化和抽象方法,给出了系统网络图的定义、制作原理、方法、步骤和特点,并进行了实例应用。本文提出的系统网络图绘制方法已应用于多个项目,实践证明,该方法是可行的。

Generalization of regional water resources deployment network chart

This paper studies the status quo of generalization of regional water resources deployment network chart at home and abroad,analyzes their element components,system structures,existing deficiencies and the study advance.The principles of water balance,natural-artificial dualistic water cycle rules,multi-water-source unified dispatch,harmonious deployment of economic system and ecosystem,etc.are the foundation of generalization of regional water resources deployment network chart.Based on the analysis of water consumption and supply versus demand equilibrium of water resources,the economy,ecosystem and water resources system are simplified into three kinds of elements: nodes(water-source nodes,water consumption nodes and water conveyance nodes),calculation units and catchments units of water conveyance.The definition,principle,characteristics,approach and method of generalization of regional water resources deployment network chart,the components,functions,and the simplifying methods of the elements and their application are proposed.The case study proves that the generalization method is feasible.
