地下水背景值在环境水文地质工作中的意义——以吉林省地下水化学背景值调研为例

THE SIGNIFICANCE OF GROUNDWATER BACKGROUD ALUE ON THE ENVIRONMFNTAL HYDROGEOLOGICAL WORK—Taking the investigation of chemical background vatue of groundwater in Jilin province as anexample

地下水化学背景值的调查研究是环境水文地质的基础性工作,具订较大的理论意义和实用价值。吉林省地下水化学背景值的调查研究成果表明,它是一份理论水平较高、实用价值大的区域性研究成果,将产生显著的经济、环境、社会效益”。下面着重分析地下水化学背景值的实用效益。一、吉林省地下水环境质量状况地下水化学背景值是地下水环境质量评价的基础和依据。它为地下水资源的合理开发利用和保护、环境影响评价和环境管理、国民经济建设和国土整治规划提供科学依据。吉林省地下水环境质量见表1.2。由表中可以看出。

The reglonal results of the whole Jilin province have been obtained through the investigation of chemical background value of groundwater in Jilin province.The author also discusses environmentai puality of groudwater in Jilin province and the quality of natural mineral water,and make a study on the relationships between the chemical background value of groundwater in Jilin province and endemic disease,and agricultural ecology.This project is very important in practice and theory.
