鲁西北地下水资源与水环境问题探讨

Discussion on Ground Water Resource and Environment of Luxibei Plan

鲁西北古河道沉积具明显的阶段性,在垂向上,古河道自下而上粒径愈上愈细;横向上,沉积物自古河道主流带向两侧变细.古河道纵向上连续性好,是优良的含水层.对古河道区的水资源进行了分析和评价,认为本区的古河道可作为供水源地.分析地下水资源赋存条件和地下水资源开发利用的现状,揭示了因超量开采地下水而引发的诸多水环境问题,提出了合理开发利用对策与措施.

The deposits of the old river channel in Luxibei plain show evident steps; The deposits of the old river channel vertically get fining--upwards and the grain sizes finer gradually from the main stream zone to the bank sides in cross drection. The old river channel is in good continaity in longitudinal direction and thus acting as good aquifers. The paper has made the analysis and evaluation for the water resource in the area of the old channel and may be considered as the water supply resource. The paper researches the environment of groundwater and today＇s status and expounds groundwater environmental problems caused by over--exploitationg of groundwater. The article presents a lot of proposals and eontermensures.
