用水效率是实施最严格的水资源管理制度的关键一环,对其进行客观评价是开展用水效率控制工作的前提。本文在传统灰靶模型中引入了CRITIC权进行客观赋权,克服了传统模型中使用等权的不足,提出了基于CRITIC权的改进灰靶模型,同时利用障碍因子诊断模型剖析了影响水资源利用效率的主要障碍因素。以2017年郑州市各地区用水效率评价为例,通过与TOPSIS法进行比较,两种方法的评价结果有很好的一致性,表明了改进灰靶模型在水资源利用效率评价中有一定的应用价值。通过障碍度模型分析,生态环境用水指标是阻碍郑州市水资源利用效率提高的主要因素。
Water efficiency is a key part of implementing the most stringent water management system, and objective evaluation of it is the prerequisite for water efficiency control. In this paper, the CRITIC weight is introduced into the traditional gray target model for objective weighting, which overcomes the shortcomings of the use of equal weight in the traditional model. An improved gray target model based on CRITIC weight is proposed. At the same time, the obstacle factor diagnosis model is used to analyze the main obstacles affecting water use efficiency. Taking the water efficiency evaluation of various districts in Zhengzhou in 2017 as an example, the evaluation results of the two methods are in good agreement compared with the TOPSIS method, indicating that the improved gray target model has certain application in the evaluation of water use efficiency. Through the analysis of the obstacle degree model, the ecological environment water use index is the main factor hindering the improvement of water use efficiency in Zhengzhou City.
