江西省水资源利用与经济协调发展脱钩分析——基于虚拟水的视角

Decoupling Relationship Analysis of the Coordinated Development Between Water Utilization and the Economy Growth in Jiangxi——Based on Virtual Water Theory

摘要:

本文基于虚拟水与水足迹理论、脱钩理论对江西省2003-2012年的水资源利用与经济发展之间的脱钩关系进行研究。结果表明,2003-2012年江西省人均水足迹均值为1783m3,高于“国际水足迹组织”测算的2011年中国人均水足迹1700m3；水资源利用效率指标从2003年4.39元/m3增加到2012年的8.57元/m3,且此期间水足迹强度呈现出明显下降的趋势,说明水资源的利用效率在明显提高,但水资源利用与经济协调发展脱钩分析显示,分析期间大部分年份江西GDP增长与水资源消耗评价结果为弱脱钩的初级协调,水资源利用效率还有待进一步提高。

Abstract:

Based on the virtual water theory, water footprint theory and the theory of decoupling, this article discusses the decoupling relationship between water resources utilization and the economic development in Jiangxi province from 2003 to 2012. The results show that the water footprint per capita mean 1783m3 during 2003-2012 in Jiangxi province, higher than 1700m3 that the International Water Footprint Organization estimates Chinese per capita water footprint in 2011, water resources utilization efficiency index increased from 4.39 yuan/m3 in 2003 to 8.57 yuan/m3 in 2012, and during this period the water footprint intensity showed a clear downward trend, indicating the utilization efficiency of water resources significantly improved. But evaluation results from decoupling analysis of the water resource utilization and economic coordinated development imply, the weak decoupling of primary coordination between GDP growth and water resources consumption in Jiangxi province during most of the year. Water resources utilization efficiency remains to be further improved.
