兰村泉域地下水污染原因及可持续开发利用对策研究

Study on Causes of Groundwater pollution and its Sustainable Exploitation and Utilization Countermeasuresin Lancun Spring Basin

为确保兰村泉域地下水资源的可持续开发利用,在现场踏勘及有关资料分析的基础上,对泉域地下水污染原因进行了研究。结果表明,兰村泉域地下水污染与以下因素有关:(1)污染物入渗;(2)地下水开采;(3)水环境化学条件变化;(4)部分地区地下水原生本底值异常。提出了泉域地下水可持续开发利用对策。研究成果为兰村泉域地下水资源保护与管理提供科学依据。

In order to guarantee sustainable exploitation of groundwater resources for Lancun Spring Basin,the article studies the causes of groundwater pollution on the basis of field observation and relative data analysis.The results indicate that the groundwater pollution in the area is related to the following factors such as(1) pollutant infiltration;(2) ground water exploitation;(3) the change of the water environmental chemistry conditions;and(4) the original background value of ground water are abnormal in some regions.The countermeasures of sustainable development of groundwater are presented.Results can provide scientific basis for the protection and management of ground water resources of Lancun Spring Basin.
