基于系统层次模糊优化模型的工业用水定额合理性研究

根据现行工业用水定额编制、修订和执行情况选取评估因子,构建评价层次结构,以江西省工业用水定额评估为例,基于系统层次模糊优化模型对现行工业用水定额合理性进行评估。结果表明:江西省工业用水定额的合理性评判等级为一般,评判等级隶属于一般、较差和较好的概率分别为39.64%、16.7%和15.1%,主要原因是,与现状用水水平对比,一些高耗水行业的定额标准明显偏高,难以在水资源管理中发挥作用,迫切需要修订。

Study on rationality of industrial water use quota based on systematic hierarchical fuzzy optimal model

Taking the evaluation of industrial water use quota in Jiangxi Province as an example, the evaluation factors were selected according to the compilation, revision and implementation of the current industrial water use quota, and the hierarchical structure of the evaluation was constructed. The rationality of the current industrial water use quota was evaluated based on the systematic hierarchical fuzzy optimal model. The results show that the evaluation grade of rationality of industrial water use quota in Jiangxi Province is general. The probability of the evaluation grade subordinating to the general, the worse and the better is 39. 64%, 16. 7% and 15. 1%, respectively. The main reason is that compared with the current level of water use, the quota standards of some high-water-consuming industries are obviously too high to play a role in water resources management, and need to be revised urgently.
