摘　　要：济南泉域岩溶地下水水质变化研究认为 ,随着经济的发展和人类活动的增强 ,水体的总硬度、SO4 2 - 、Cl- 和 NO- 3等指标均呈上升趋势 ,且近期离子浓度升高的速率加快。从泉域间接补给区到直接补给区再到排泄区 ,地下水污染逐步加重 ,水质逐渐变差。WT5BZ]Study on the variation of groundwater chemical components of Jinan spring basin shows that the concentration of all the items, such as total hardness, SO 4~ 2-, Cl^-, NO 3^-, is increased with the enhancement of human activity, and ionic concentration rises rapidly in the recent time. The groundwater is polluted more and more intensely and the water quality gets worse and worse from indirect recharge area via direct recharge area to discharge area.
