| 摘 要： | 通过野外调查获得的大量资料,分析松嫩平原不同地貌单元、不同深度地下水水位下降状况,以及由于地下水位下降引起的环境负效应。研究发现,在过去的20年中,松嫩平原潜水水位普遍下降了2-5m,第四系承压水头下降了1-2m。地下水位下降导致湿地面积萎缩,泉水流量变小或消失,土地沙化加剧等环境负效应,部分地区由于深层承压水头下降,上层劣质潜水透过弱透水层下渗污染承压水。

| Abstract: | By using the datum of 2003-2005 obtained from field study,we analyzed the different geomorphic units,the groundwater lowering of different aquifers in Songnen Plain and the negative environmental effect raised by the decline of groundwater level.The investigation discovered that in the past 20 years,the phreatic water level in Songnen Plain generally declined 2 to 5 meters;confined water level of Quaternary System has been declined 1 to 2 meters.The depressions of groundwater level also caused negative envi... |
