| 摘 要： | 本文利用上世纪70年代和本世纪初的水位对比和典型孔组的水位历时变化曲线,分析安徽省淮北平原孔隙水水位动态及历史变化。结果表明:多年来持续开采地下水,改变了淮北平原孔隙水水位动态类型和不同流动系统地下水的补排关系,加剧了孔隙水水位变化的随机性;集中开采区的中深部孔隙水水位动态变化尤为显著,水位持续大幅度下降,原自流区消失,并诱发地面沉降等地质环境问题。

| Abstract: | Based on water level comparison between 1970s and early this century and water level versus time curve of typical hole group,this paper analyzed dynamic and historical change in pore water level in the Huaibei plain.The results indicate that continuous exploitation of groundwater for many years past has changed dynamic type of pore water level as well as feeding-drainage relation of groundwater of different flowing systems,and intensified the randomness of change in pore water level;centralized exploitation... |
