中文摘要：

＂泉城＂济南是一个富含岩溶地下水的城市,泉水甘甜。近年来,城市化发展带来环境污染。为查明重金属在岩溶地下水的分布特征,选取代表性元素Pb作为研究对象,对研究区的164个岩溶地下水样品进行了Pb含量的分析。分析结果表明,研究区内岩溶地下水中Pb元素含量不仅在空间上分布有规律,同时也跟工业废水和废渣排放、水位埋深及其它元素和离子之间有相关关系,进一步分析污染来源,为研究区域岩溶水环境污染防治提供科学依据。

英文摘要：

Jinan is famous for its karst groundwater and is called spring city with its sweet water. However , at the same time of the urbanization bring economic prosperity to our city and it also brought pollution to our environment as well. To find out the distribution characteristics of heavy metals in the karst groundwater, the Lead was selected as the representative element research object and164 samples of karst groundwater are analyzed in the study area. Through the analysis of karst groundwater in Lead content the author found that the Lead content is not only related to the＇ spatial distribution regularities but also associated with industrial wastewater and waste residue discharge and also has correlation relationship with other Elements. To provided the scientific basis for prevention and control of karst water environment pollution. , the article further analyzes the sources of pollution.
