摘要
为客观评价区域的用水水平,采用基于欧式贴近度的模糊物元模型综合评价区域水资源开发利用程度.将灌区用水水平的不同阶段作为物元的事物,将各阶段的评价指标及其模糊量值作为复合模糊物元,通过计算复合模糊物元与标准物元之间的欧式贴近度,综合分析区域水资源的开发利用现状,确定区域用水水平,为水资源的进一步开发利用及合理配置提供决策依据.以宝鸡峡灌区为例,研究结果表明,宝鸡峡灌区的用水水平处于发展阶段,水资源开发利用已具有一定规模但仍有开发潜力.
In order to evaluate regional water resources utilized level,a new method based on the fuzzy matter-element analysis and Euclid approach degree is put forward.Regarding the regional samples and the utilization phases as the object of matter-element,and the compound fuzzy matter-element with the evaluation factors and their fuzzy value of the object is constructed.According to the practical example of water resources development and utilization of Baojixia irrigation area,the evaluation result can be achieve...
