摘要
选取西安市人均占有水量、人均供水量、水资源开发利用率等10项定量指标,结合云模型理论构建水资源可持续利用预警分级指标体系,借助熵权法确定各个指标的权重。结果表明,与模糊物元法和模糊层次分析法相比较,基于熵权的分级预警云模型结果更为合理,西安市的水资源利用处于一个较为正常的阶段,根据综合云隶属度进行水资源可持续利用预警从高到低排名依次为:临潼区、西安全市、长安区、鄠邑区、主城区、周至县、高陵区、蓝田县。
Combined with the cloud model theory, 10 quantitative indexes such as per capita water, per capwater supply, water resource utilization and development rate, etc. are selected to set up early-warning gradiindex system of sustainable water resources utilization in Xi？an City. The weight of each index is determined wthe entropy weight method. The results show that compared with fuzzy matter-element method and fuzzy analyhierarchy process method, the results of grading warning cloud model based on entropy weight are more reasonaband the utilization of water resources in Xi？an is in a relatively normal stage. Judging from the comprehensive clomembership degree, the early warning of water resources sustainable utilization is ranked in proper order from hito low Lintong District, Xi？an City, Changan District, The Hu Yi District, downtown area, Zhouzhi CountGaoling District and Lantian County.
