摘要该文基于水资源生态承载力模型方法计算贵州九市、州2000-2018年地下水资源承载力和分析空间演变特征,并且用泰尔指数进行差异测度。结果表明,从行政区来看,各市、州无论地下水资源生态承载力总量或者地下水资源承载力模数变化均具有一定的波动性,并具有明显三个档次,处于第一档次的是黔东南、遵义市、毕节市和黔南州;处于第二档次的是铜仁市、黔西南;处于第三档次的是六盘水市、安顺市和贵阳市。从流域来看,贵州"两江"流域的地下水资源承载力总量和承载力模数变化也存在一定的波动性,贵州长江流域的地下水资源承载力总量的多年平均值是贵州珠江流域的2.3倍,而地下水资源承载力模数比贵州珠江流域多2.9×10^(5)hm^(2)/a。通过泰尔指数的测度表明地下水资源承载力模数整体水平差距比较小,贵州各市、州以及"两江"流域地下水资源生态承载力的年际变化都比较小,其形成机制主要是自然因素和人为因素差异的影响。 The groundwater carrying capacity from 2000 to 2018 is calculated based on the ecological footprint model,and the spatial evolution characteristics are analyzed,and the Theil index is used to measure the difference in nine cities and autonomous prefectures of Guizhou in this paper.The results show that,from the perspective of administrative regions,the change of total carrying capacity of groundwater resources and the modulus have certain volatility,and have three obvious grades,Qiandongnan,Zunyi,Bijie and Qiannan are in the first grade;Tongren and Qianxinan are in the second grade;in the third level are Liupanshui,Anshun and Guiyang.From the perspective of river basins,the total carrying capacity and modulus of groundwater resources are also fluctuating in Guizhou’s"two rivers"basin.The annual average value of the total carrying capacity of groundwater resources in the Yangtze River Basin of Guizhou is 2.3 times of that in the Zhujiang Rive Basin of Guizhou Province,while the modulus of groundwater resources carrying capacity is 2.9×10^(5) hm^(2)/a more than that of the Zhujiang Rive Basin in Guizhou Province.The results show that the overall level gap of modulus of carrying capacity is relatively small,the interannual variation of carrying capacity of groundwater resources is relatively small in cities,prefectures and"two rivers"basins,the formation mechanism is mainly affected by the differences between natural factors and human factors.
