地下水环境背景值研究进展的分析与建议

Discussion of the Problemsand Suggestions for Natural Background levels in Groundwater

在论述地下水环境背景值研究的有关基本概念以及中国地下水环境背景值现状的基础上,同时对比多种地下水环境背景值的计算方法,指出了中国地下水环境背景值研究中存在的问题,并提出在采样点的布置过程中,处理异常值的过程中,选择环境背景值范围的过程中,需要对有关水文、环境地质条件的变化,数理统计方法的应用等进行进一步的研究,为地下水水质的准确评价和水化学研究提供可靠的依据,为中国的地下水环境背景值研究提供切实的参考价值。

This paper introduces some basic concepts related to natural background levels in groundwater study and thedevel-opment of its main content and points out the deficiencies of it. At the same time calculation method of background of groundwater environment compared to a variety of values,points out the problems in the study of environmental background value of groundwater in China,and put forward in the process of layout of sampling points in the process of treatment of abnormal value in the process of selection of environmental background values in the range,the need for changes in the hydrological and geological environment conditions,further the research on the application of mathematical statistics method,to provide a reliable basis for accurate evaluation of groundwater quality and water chemistry research,provide practical reference value for the research of groundwater environment background value of our country.
