| 摘 要： | 大同市平原区地下水历年严重超采 ,造成了地下水持续大面积大幅度下降 ,从而形成了总面积 93 .6km2 的 4个地下水降落漏斗 ,最大漏斗区中心水位下降达 30m ,随之引发了大面积地面沉降 ,地裂缝出现并不断发展 ,总长度达 18.8km。另外 ,由于废污水的排放、引污灌溉、工业生活废渣的堆积 ,造成地下水质污染 ,使得水环境地质状况进一步恶化

| Abstract: | In this paper ,the present situation of groundwater extraction in Datong city area is introduced,the existing problems are summarized as:continous and heavy drawdown of groundwater table in large area, enlarging thereby the groundwater depression cone year by year;increasing of land subsidence;developing of ground crack;and worsening of groundwater quality.Then the correlation between groundwater overdrafting and land subsidence,the correlation between groundwater overdrafting and ground crack,and the correlation between the drawdown of groundwater table and groundwater pollution are analysed,the conclusion is that the groundwater overdrafting and the groundwater pollution are the cause making the environment geology poor. |
