人类活动对鲁北平原地下水环境影响特征研究

从近10年来对鲁北平原地下水环境问题的调查成果出发,论述了人类活动对鲁北平原地下水环境的影响特征,包括浅层地下水污染、含水层疏干等的分布、形成规律及发展趋势.鲁北平原浅层地下水主要污染物为三氮、砷、铅等重(类)金属,个别地方存在有机物污染.深层含水层疏干主要发生在长期以深层地下水作为生活和工业水源的德州,深层含水层疏干引发了地面沉降;浅层地下水疏干发生在以浅层地下水为农业供水水源的冠县和宁津县.通过对鲁北平原地下水环境问题的分布现状、产生原因及规律、发展趋势及其危害的研究,提出了相应的预防措施及可持续发展对策.

Characteristic research on the influence of human activities on groundwater environment in northern Shandong plain

Based on research of the environmental problems of groundwater in northern Shandong plain in the past 10years, the impact of human activities on the groundwater environment was analyzed, including shallow groundwater pollution and aquifer dewatering, and its distribution, formation of law and development trend. The pollutants of shallow groundwater in the northern Shandong plain included nitrogen, heavy metal such as As and Pb, and organic. The deep confined aquifer dewatering occurs mainly in Dezhou where deep groudwater exploration have last for a long period. The deep confined aquifer dewatering triggered land subsidence. The shallow groundwater dewatering occurred in Guanxian and Ningjin where shallow groundwater was the main water supply for agriculture. Through the study on the distribution, causes, trends and its hazards of environmental problems of groundwater in study area, the paper raised appropriate precautions and sustainable development strategy.
