包气带硝酸盐分布的差异性及其形成机理:以正定、栾城为例: 在地表等量氮输入条件下,包气带中硝酸盐含量分布是其抗污染能力的直接表征。阐明不同包气带中硝酸盐分布的差异并分析其成因对于评价下覆含水层的硝酸盐污染脆弱性、保护地下水资源免遭硝酸盐污染,具有重要意义。本文基于太行山山前冲洪...; 袁利娟庞忠和; 关键词：包气带硝酸盐含量; 文献传递

近30年来降水量变化和人类活动对北京潮白河冲洪积扇地下水动态的影响被引量：9: 2010年; 对北京潮白河冲洪积扇分布区30年来降水量、地表径流量、地下水水位和地下水储存量进行了时间序列分析。结果表明:过去30年中,区域地下水动态发生了明显变化,特点是1998年以来,地下水位和地下水储存量迅速下降与减少。1998年以来,年降水量为以往多年平均值的76%左右。在储存量变化的影响因素中,降水量减少导致的补给量减少约占24%,人类活动,如工农业地下水开采、应急水源地地下水开采和地表水体入渗减少等因素约占76%。由于未来气候变化的不确定性,在南水北调的水进京后仍可能出现连续枯水年,因此,以丰水年降水进行水源涵养存在较大风险。对于已经处于严重超采状况的潮白河冲洪积扇来说,为了满足未来供水的需要,应急水源地从现在起应减少开采量或停采以逐步恢复地下水储存量。; 刘记来庞忠和王素芬孔彦龙周俊; 关键词：地下水动态降水变化
