地下水资源对新疆经济社会支撑作用的定量评价

为探究地下水资源在新疆各地、市、州经济社会发展过程中发挥支撑作用的情况，构建了涵盖地下水依存度、综合用水效率和地下水开发潜力3方面的指标体系，运用SMI-P方法对2004—2016年新疆各地、市、州地下水资源对经济社会的支撑作用进行了定量评价与分析。结果表明:随着经济的发展、人口和耕地的增加，新疆一些地区地下水资源对经济社会的支撑作用明显增强，如伊犁州、巴州、塔城地区等；地下水资源对新疆各地、市、州经济社会发展的支撑作用空间差异较大，地下水资源对东疆和北疆地区经济社会的支撑作用强于南疆地区；东疆和北疆大部分地区经济相对发达，对地下水的依存程度和综合用水效率都处于较高水平，地下水开发潜力较小，开发空间不足，而南疆地区地下水开发潜力较大，地下水可为其未来经济社会的发展提供进一步支撑。

Quantitative evaluation of groundwater resources supporting economy and society in Xinjiang

To explore the supporting role of groundwater resources in the process of economic and social development of cities in Xinjiang, an index system covering three aspects of groundwater dependency, comprehensive water efficiency and groundwater exploitation potential was constructed, and the SMI-P method was used to quantitatively evaluate and analyze the supporting role of groundwater resources in the economy and society of Xinjiang from 2004 to 2016. The results show that, with the development of economy and the increase of population and cultivated land, the supporting role of groundwater resources to the economy and society in some cities of Xinjiang has been significantly enhanced, such as Ili Kazak Autonomous Prefecture, Bayingol Mongolian Autonomous Prefecture, Tarbagatay Prefecture, etc. The supporting role of groundwater resources in the economic and social development of each city is quite different, and the supporting role of groundwater resources in the eastern and northern Xinjiang is stronger than that in the southern Xinjiang; Most of eastern Xinjiang and northern Xinjiang have relatively developed economies, and their dependence on groundwater and comprehensive water utilization efficiency are both at a high level, with less potential for groundwater exploitation and insufficient development space. Southern Xinjiang has a great potential for groundwater exploitation, which can provide further support for its economic and social development in the future.
