新疆地区水资源退化趋势及其产业原因研究——基于灰水足迹和脱钩指数

WATER RESOURCE DEGRADATION TREND AND ITS INDUSTRIAL CAUSES IN XINJIANG BASED ON GREY WATER FOOTPRINT AND DECOUPLING INDEX

文章从灰水足迹视角分析了2004—2014年新疆地区水资源退化趋势,引入脱钩指数分析其经济发展水平与水资源环境的协调程度,从产业结构的角度剖析该地区水资源退化的原因。结果表明:2004—2014年新疆灰水足迹总体增加,水资源退化趋势显著;其经济发展水平与水资源环境处于初步协调状态;农业扩大生产对水资源退化的影响力最大。因此,提出新疆应尽早调整产业结构,摆脱社会发展对农业的过分依赖,同时在产业转型中重点关注取水控制和污染防治,以实现新疆地区水资源反退化和社会经济可持续发展。

This paper analyzes the water resource degradation trend in Xinjiang in 2004 to 2014 from perspective of grey water footprint, and uses decoupling index to study their coordinated degree between economy and water resource environment and discusses the causes of water resource degradation from industrial perspective. In 2004 to 2014, grey water footprint rose with a worsening water resource degradation trend, indicating a preliminary coordination between its economy and water resource environment, most contributed by expanded agricultural production. This paper presents suggestions on adjusting industrial structure, freeing overdependence of social development upon agriculture, and focusing on water supply controls and pollution prevention during industrial transformation, so as to prevent water resource degradation and to reach a sustainable development in Xinjiang.
