【摘要】 该文分别考虑了包括节水水平、生态环境建设、经济发展、社会保障等方面的指标,在构建了一个具有层次结构的节水型社会的评价指标体系的基础上,利用层次分析法确定了指标权重,通过对各个体指标的发展趋势和与国外的用水水平进行横向比较后确定了不同指标的标准值,并建立了"综合目标分层次评价模型"进行节水型社会发展水平的量化综合评价。该评价模型由节水型社会目标模型和节水型社会发展子模型(Dt)、节水型社会保障系统子模型(St)2个子模型构成。以水利部确定的节水型社会试点城市绵阳为例,进行节水型社会综合评价的实例研究,分别计算了绵阳市的节水型社会评价综合指数、以及节水型社会发展子系统和保障子系统的实现指数。研究结果表明,2000年节水型社会发展指数仅为10 2%,节水型社会建设需要进一步发展,各区域的节水型社会的发展程度存在明显差距,绵阳市节水型的社会经济发展模式还有待进一步的提高。更多还原

【Abstract】 Accurate evaluation on the progress of water conservation society provides an efficient tool to improve water use efficiency and water resources management. It is necessary to carry out comprehensive analysis on the context of water resources-ecology-economic systems. In this paper, fully consideration is given to the indicators that could reflect water conservation level, ecology, economic development and social equity as a whole. Based on the three-hierarchy evaluation indication system for water conservation society, 26 indexes in agriculture, industry and domestic water uses, as well as the economical and ecological indexes are chosen. AHP method is employed to analysis the weight of the indication system. The standards of the indexes are given to analyze the developing trends at home and comparing with the advanced conservation level abroad. The method to evaluation the total goal by the hierarchy weight is established to quantify the progress in constructing water conservation society. The model, including a systematic model, and two sub models (Dt),(St) is developed to give an exact explanation on the situation of water conservation, economic development and social equity toward a water conservation society respectively. With the results by the model, the advances toward a water conservtion society are divided into five periods. As an example, Mianyang city, which is the experimental city of constructing water conservation society, is chosen to take experimental study. The results by the model show that the mark of the development of water conservation society in Mianyang is only 10.2% in 2000,and a large difference is seen among the cities and counties of Mianyang. The index of the two-sub system is also calculated. There is a long way to make progress in constructing water conservation society, which is also the result of reasonable social and economic development.更多还原
