摘要
笔者以2017年取样化验的各项水质指标数据为基础,选取19种离子及若干种有机物对荆泉水源地进行地下水水质现状评价。其间利用收集的监测点历年水质资料,通过Spearman秩相关系数法分析地下水水质变化趋势。当前,人们要进一步做好水源地保护工作,确保荆泉水源地的区域水环境安全。
Based on the water quality index data of sampling and testing in 2017,the author selected 19 ions and several organic substances to evaluate the current groundwater quality of Jingquan water source.In the meantime,using the collected water quality data of monitoring points over the years,the Spearman rank correlation coefficient method was used to analyze the change trend of groundwater quality.At present,people must do a better job of protecting the water source area to ensure the safety of the regional water environment of the Jingquan water source area.
