【摘要】 通过野外实地调查和水化学监测，将莱州湾南岸平原浅埋古河道带及冲洪积扇浅层地下水水化学环境分为３大区域，即北部的全咸水区、中部的咸淡水过渡区和南部的全淡水区．在３个系统的浅埋古河道带内的全淡水区，仍有水化学特征的南北向差异．浅层地下水水化学特征具有年内及年际变化规律．人类应合理开发利用地下水资源，防止咸水入侵和人工污染，保持良好的地下水水环境更多还原

【Abstract】 By field investigation and water chemical monitoring, the groundwater environment of the shallow buried paleochannel zones and alluvial diluvial fans on the south coast plain of Laizhou Bay can be divided into 3 area: the salt groundwater district in the north, the transition district in the middle and the fresh groundwater district in the south. In the fresh groundwater district, the chemical characteristics of the groundwater exist still differences in S N direction. The chemical characteristics of the shallow groundwater in the area exist interseasonal and interannual change regularities. The measures of rational developing and utilizing the groungwater resources, of preventing the salt water intrusion and artificial pollution, and of keeping a good groundwater environment should be taken in the area.更多还原
