摘　　要：通过对铜仁市玉碧松工业园区中的4个园区周边土壤夏季和冬季取样,分别检测了其中Cr、Cu、Pb、Cd、As和Hg6种重金属含量,根据单因子污染指数法和内梅罗综合污染指数法进行了评价,得出结果以GB36600-2018第二类用地筛选值为评价标准。结果显示:4个工业园区周边的土壤处于清洁和尚清洁的状态;从夏季和冬季的数据表明,4个工业园区周边土壤重金属的含量呈现出Cr>Pb>Cu>As>Hg>Cd的趋势;四个工业园区Cr、Pb、Cu、As夏季和冬季含量的变化趋势各有不同,而Cd、Hg的含量则比较稳定,其值均远低于背景限制。Soil samples were collected in summer and winter from surrounding areas of the four Industrial Park in Tongren,and six elements such as Cr,Cu,Pb,Cd,As and Hg in the soil were determined by Atomic absorption spectrophotometer and Atomic Fluorescence Spectrometer.The single factor pollution index method and Nemero Comprehensive pollution index method was used to evaluate the pollution of heavy metals to the surrounding Industrial Park soil.The result was based on the second category of GB36600-2018 land use screening as the evaluation standard.The results showed that the soil around the four industrial parks is in a clean or monk-clean state.According to the data in summer and winter,the contents of heavy metals in the soil around the four industrial parks showed a trend of Cr>Pb>Cu>As>Hg>Cd.The trends of Cr,Pb,Cu and As contents in the four industrial parks were different in summer and winter,but the contents of Cd and Hg were relatively stable,and their values were far below the background limit.
