摘　　要：察尔汗盐湖东采区储卤层降落漏斗自1984年形成以来,长期呈现增长趋势,但在2011—2019年呈现出减小趋势。本研究通过分析2003—2019年降落漏斗及其相关因素的变化趋势结合Pearson相关性分析结果发现,2003—2009年降落漏斗面积增大的主要驱动因素为卤水开采活动(r=0.847,p=0.016)和蒸发作用(r=0.962,p<0.001);2011—2019年降落漏斗面积减小的主要驱动因素为驱动补水溶矿工程(r=0.908,p<0.001),因此建议补采比取0.8,这样既能保证卤水开采量又能恢复东采区卤水水位。该研究对察尔汗盐湖补水溶矿和水资源配置方面具有一定的指导意义。The subsidence funnel area of the brine storage layer had been increasing since it formed in1984 in the eastern mining district of Qarhan Salt Lake,but it shows a decreasing trend from 2011 to 2019.In this paper,by analyzing the change trend of the subsidence funnels and their related factors from 2003 to 2019,combined with Pearson correlation analysis,it was found that the main driving factors for the increase of the subsidence funnel area from 2003 to 2009 were brine mining activities(r=0.847,p=0.016),evapotranspiration(r=0.962,p<0.001);the main driving factor for the decrease of the funnel area from 2011 to 2019 drives the water supplement and dissolution engineering(r=0.908,p<0.001).It is suggested that the ratio of supplementary mining should be 0.8,which can ensure both the exploitation of brine and the recovery of brine level in the eastern mining area.This study has certain guiding significance for the driving water-supplement dissolution and water resources allocation of Qarhan Salt Lake.
