基于水资源生态足迹的陕西省水资源利用与经济增长的脱钩分析

Decoupling Analysis of Water Resources Utilization and Economic Growth in Shaanxi Province Based on the Ecological Footprint of Water Resources

为定量分析陕西省水资源利用与经济增长之间的关系,基于水资源生态足迹理论分析二者之间的脱钩关系并对其脱钩状态进行预测。结果表明:2005-2018年陕西省水量资源生态足迹与经济增长均处于脱钩状态,但并未实现完全脱钩;水质生态足迹与经济增长由扩张性负脱钩和弱脱钩向强脱钩发展;综合视角下陕西省处于水量型弱脱钩状态。通过预测发现陕西省水量资源生态足迹与经济增长的脱钩关系向良性发展,而水质生态足迹与经济增长的脱钩强度在降低,综合视角下水资源利用与经济增长的脱钩矛盾由水量型转化为水质型,因此陕西省必须加大污水治理力度。根据研究结果,本文为陕西省水资源利用与经济增长的脱钩发展提出了相关建议。

In order to analyze the relationship between water resources utilization and economic growth quantitatively in Shaanxi Province,based on the theory of water resources ecological footprint,this paper analyzes the decoupling relationship and makes decoupling predictions between the two.The results show that the water resources ecological footprint and economic growth in Shaanxi Province are in a state of de⁃coupling from 2005 to 2018,but they have not been completely decoupled.The relationship between water quality ecological footprint and economic growth has developed from expansive negative decoupling and weak decoupling to strong decoupling.From a comprehensive per⁃spective,Shaanxi Province is in a state of weak water-based decoupling.Through forecasting,it is found that the decoupling relationship be⁃tween water resources ecological footprint and economic growth in Shaanxi Province towards a benign development,while the decoupling in⁃tensity between water quality ecological footprint and economic growth is decreasing.From a comprehensive perspective,the contradiction between the decoupling of water resources utilization and economic growth is transformed from water quantity type to water quality type.Therefore,Shaanxi Province must increase sewage treatment efforts.According to the research results,this paper puts forward relevant sug⁃gestions for the decoupling development of water resources utilization and economic growth in Shaanxi Province.
