长江经济带采矿用地时空分异及驱动因素研究

Study on spatio-temporal distribution and driving factors of mining land in the Yangtze River Economic Belt

近年来,长江经济带矿业开采累计占用、损坏土地增长迅速,影响其绿色与集约发展。本文运用基尼系数、不平衡指数及因素分解模型对2009-2016年长江经济带采矿用地的时空分异及驱动因素进行研究,结果表明:长江经济带采矿用地规模大且区域差异明显;长江经济带采矿用地与矿业产值匹配相对合理,且保持相对稳定;单位劳动产出的提高是该区域采矿用地扩张的最大驱动因素,矿山企业数量的减少是最大抑制因素;单位产值用地规模和企业平均从业规模作用阶段性明显。最后提出合理控制采矿用地规模,促进长江经济带高质量发展的对策建议。

In recent years,the cumulative occupation and damage of land by mining in the Yangtze River Economic Belt has increased rapidly,affecting its green and intensive development.The paper analyzes the spatio-temporal differentiation and driving factors of mining land in the Yangtze River Economic Belt from 2009 to 2016 by using Gini coefficient,disequilibrium index and factor decomposition model.The results show that the scale of mining land in the Yangtze River Economic Belt is relatively large and the regional differences are obvious.The matching of mining land and mining output value is relatively reasonable and relatively stable.The increase of unit labor output is the biggest driving factor to the expansion of mining land,while the reduction of mining enterprises number is the biggest restraining factor.The effect of the number of land per unit output value and the average employment scale of enterprises are obvious in stages.Finally,some countermeasures and suggestions are put forward to reasonably control the scale of mining land and promote the high-quality development of the Yangtze River Economic Belt.
