摘要
依据洞庭湖区浅层地下水1720个水质检测数据,运用格拉布斯(Grubbs)准则和拉依达准则剔除异常数据,再运用数理统计方法和SPSS软件确定概率分布类型和不同类型的地下水的环境背景值,为该地区地下水污染评价和治理修复提供了重要的地球化学依据。
According to the dection of water quality data obtained from Dongting Lake,the exceptional data are removed by Grubbs statistical method and Panta statistical method,the probability distribution of the data and the environment background values of different groundwater are obtianed by applying mathematical statistics and SPSS statistical software,making the corresponding standards and providing important geochemical data for groundwater pollution appraisal and repairing.
