多目标约束下区域水资源优化配置研究

随着社会经济的快速发展,用水需求增加与水资源短缺、水资源污染之间的矛盾日益尖锐,使得水资源已经成为制约区域社会经济发展的瓶颈。文章在综合考虑经济、社会、生态等因素的基础上,建立区域多目标水资源优化配置模型,实现从传统的单目标约束向多目标约束转变的新研究思路。在多目标约束下以济宁市为研究对象,通过建立模型和对优化配置结果的分析,诊断出济宁市农业和工业存在严重缺水情况,超过全市平均缺水率的城市有市中区、任城区、曲阜市、邹城市、泗水县和嘉祥县。研究结论将为区域水资源优化配置、落实最严格水资源管理制度提供决策依据。

Study on optimal allocation of regional water resources under constraint of multi-objective

With the rapid development of social economy, the conflict between the increase of water demand and shortage ,pollution of water resources has become increasingly acute, which make water resources become a bottleneck of regional social and economic development. This paper established a model of regional multi-objective optimal allocation of water resources based on the comprehensive consideration of factors such as economy, society and ecology,which realized a research idea of change from the traditional single objective constraint to multi-objective constraints. Taking Jingling city as a research subject uder multi-objective constraints, through the establishment of model and the analysis of results,the paper got the result that agriculture and industry are faced with serious water shortage situation. Renchen, Shizhong, Qufu, Zoucheng, Sishui, Jiaxiang all exceed the average rate of water shortage in Jining.The result can provide decision basis for allocation of regional water resources and the most strict system of water resources management.
