摘要
以安徽省资源型城市为样本区域,建立“人口-水质-水量-社会”评价体系;采用秩和比综合评价法,分级评价安徽省资源型城市水资源承载力;借助标准差椭圆和地理探测器分析研究区域水资源承载力的空间分异性及驱动因子的解释力大小。结果表明:2011—2021年,安徽省资源型城市的水资源承载力指数整体相对较低,2011—2015年以Ⅱ级(超载)状态为主,2015—2021年逐渐改善为Ⅲ级(临界)或Ⅳ级(不超载);安徽北部城市水资源承载力比南部城市更低,但增速较快,不均衡的水资源承载力分布格局正逐步改善;对各市水资源承载力空间分异性解释力最大的因子为生态补水用水量,其次为水污染次数和采掘业从业人员数。
Resource-based cities in Anhui Province are taken as sample areas the population-water quality-water yield-society evaluation system was established.The rank-sum ratio comprehensive evaluation method was used to grade the water resources carrying capacity of resource-based cities in Anhui Province.Finally the spatial differentiation of regional water resources carrying capacity and the explanatory power of driving factors were studied by means of standard deviation ellipse and geographic detector.The results show that the water resources carrying capacity of resource-based cities in Anhui Province was relatively low as a whole from 2011 to 2021 mainly in the state ofⅡoverload from 2011 to 2015 and gradually improved toⅢcritical orⅣno overload from 2015 to 2021.The water resources carrying capacity in the northern cities of Anhui is lower than that in the southern cities but the growth rate is faster and the unbalanced water resources carrying capacity distribution pattern is gradually improving.The factor with the greatest explana-tory power to the spatial heterogeneity of the water resources carrying capacity in each city is the water consumption of ecological water replenishment followed by the number of water pollution and the number of workers in the mining industry.
