水资源利用与经济发展协调关系探析

Analysis on the coordination relationship between water resources utilization and economic development

为了研究区域水资源利用与经济发展的协调性,基于水足迹理论,计算了连云港市2008-2017年10年的水足迹和相关评价指标的值,并构建脱钩评价模型,从宏观层面探索连云港市水资源利用与经济发展的协调性关系。结果表明,2008-2017年期间,连云港市人均水足迹在1.01 hm^2上下波动,农业用水是水足迹的主要组成部分;仅考虑本地水资源,水资源压力指数较大,连云港用水主要依靠外调水;从水资源利用效率来看,10年间水资源利用效率不断提高,水资源利用与经济增长基本处于协调发展阶段。

In order to study the coordination between regional water resource utilization and economic development,based on the water footprint theory,the water footprint of Lianyungang City from 2008 to 2017 and the values of relevant evaluation indexes were calculated,and a decoupling evaluation model was constructed to explore the coordination relationship between water resource utilization and economic development in Lianyungang City from a macro perspective.The results showed that from 2008 to 2017,the per capita water footprint of Lianyungang City fluctuated around 1.01 hm^2,and agricultural water use was the main component of the water footprint.Considering only the local water resources,the water resource stress index was relatively large,and the water consumption of Lianyungang mainly depended on external water transfer.From the perspective of water resource utilization efficiency,the water resource utilization efficiency had been continuously improved over the past 10 years,and the water resource utilization and economic growth were basically in a coordinated development stage.
