摘要
为明确新疆水资源开发利用的空间均衡程度,选取与水资源开发利用相关的12个指标,采用空间均衡度计算方法,计算了2004—2017年新疆各地州各指标的空间均衡系数及水资源开发利用的总体空间均衡度,并与采用基尼系数方法的计算结果进行了对比。结果表明,新疆各地州的城镇化率及单位面积农田灌溉用水量在空间上较为均衡,而水资源开发利用率的差异最大;2004—2017年新疆水资源开发利用的总体空间均衡度呈现缓慢上升趋势,水资源开发利用的空间不均衡现象有所改善;空间均衡度计算方法与基尼系数计算方法具有较好的长期一致性,分析空间均衡的变化应以长期的变化趋势为基础。
In order to explore the spatial equilibrium condition of water resources development and utilization in Xinjiang,this research selected 12 indicators related to the development and utilization of water resources,and calculated the spatial equilibrium coefficient in every region and global spatial equilibrium degree of each indicator from 2004 to 2017 by using the calculation method of spatial equilibrium degree,and then the calculated results were compared with those of Gini coefficient method.The results show that the spatial distribution of urbanization rate and irrigation water consumption per unit area were balanced,while the regional difference of water resources exploitation and utilization rate was the largest.From 2004 to 2017,the global spatial balance of water resources development and utilization in Xinjiang showed a slow rising trend,and the spatial imbalance of water resources development and utilization was improved.The calculation method of spatial equilibrium degree has a good long-term consistency with that of Gini coefficient,and the analysis of spatial equilibrium should be based on the long-term change trend.
