摘要
通过对研究区内多年水质监测资料的分析,查明了昆明盆地浅层地下水中三氮的含量及其分布规律,在此基础上,从地下水污染源、区内的地质环境条件以及地下水开采等方面探讨了地下水中三氮的迁移、转化及其污染机理。最后,指出三氮污染已成为昆明盆地浅层地下水污染的普遍问题,地下水三氮入湖通量在一定程度上对滇池的富营养化发展起了作用。
The 3-nitrogen content and distribution of the fleet layer groundwater in Kunming basin was studied through the analysis of water quality in the research area.On the basis,this paper discussed the mechanism of the 3-nitrogen transferring,transforming and polluting from the following aspects: the pollution resources,geology environmental conditions and the groundwater exploitation.In conclusion,the 3-nitrogen pollution has become a common problem of the fleet layer groundwater of Kunming basin,to some extent;the 3-nitrogen input flux takes important role on the eutrophication of Dianchi Lake.
