| 摘 要： | 通过对历史资料的对比,揭示了济南某地裂隙岩溶地下水中硝酸根污染现状,并通过三线图法对硝酸根进行溯源分析,显示研究区地下水硝酸根含量受人类活动影响明显,并有进一步发展的趋势。相关性分析法分析结果显示地下水硝酸根含量与Cl相关,说明其与工业废水联系密切,而土壤剖面中硝酸根含量显示,土壤中硝酸根含量的顺序为:禽畜粪便污染类污水排放污染类垃圾堆放污染类。分析认为,研究区裂隙盐溶承压水硝酸根污染的来源主要为补给区及径流区强烈渗漏携带牲畜粪便及氮肥和农家肥的施用、生活污水、工业废水及浅层水混入。

NITRATE POLLUTION SITUATION AND SOURCE TRACING OF FISSURE KARST GROUNDWATER IN SOME AREA,JINAN |

| Abstract: | Comparative historical information,we explain the NO3- pollution situation of fractured karst groundwater in some area of Jinan. Moreover,by tracing the source of NO3- through piper plot,we conclude that NO3- pollution is significantly affected by human activities,and have further development trend;The correlation matrix show that NO3- pollution is related to Cl,illustrate that industrial waste water can also affect NO3-content.The order of NO3- content in soil is:livestock&poultry stool pollution>sewage disposal pollution>dumping pollution.Base on the above,we infer thatthe source of fractured karst groundwater NO3- pollution is:livestock&poultry stool pollution, sewage disposal pollution, dumpingpollution,and shallow surface and ground water mixing,especially in the strong linking area of the rechargearea,run off area,and drain area. |
