| 摘 要： | 在对云南师宗县烤烟GAP基地土壤、水源重金属残留状况进行系统调查后，对烟区土壤、水环境质量按照国家有关标准进行综合评价。结果表明：土壤重金属单因子污染指数最小的是Pb，其次为Hg和Cd，最大的为As，污染指数达到0.544,其中1个土样存在Cd污染，2个土样存在As污染，土样超标率达到23.08%；就综合污染指数而言，土壤Pb,Hg,Cd,As分别为0.203,0.455,0.680和1.306（＞1.0）, 说明该基地土壤As存在轻度污染，Cd存在潜在危害,这是需要引起关注的。但随机抽取的7个水样中，仅1个水样Hg含量超标，说明该基地水质符合优质烟叶生产的需求。

| Abstract: | Results of the investigation and analysis of the soil in flue-cured tobacco GAP plots in Shizong county showed that the single factor pollution index with Hg was the lowest,and followed by that with Pb and Cd whereas that with As was the highest,the pollution index of Cd arrived 0.544, and the Cd content of one of these soil sample excess the secondary standard,the As content of two excess the secondary standard,arrived 23.08 percent.In regard to combined pollution index,the Pb,Hg,Cd,As of soil sample arrived 0.203,0.455,0.68 and 1.306(>1.0),which show the As of soil in experiment exist district pollution and Cd exist potential harm,which should arouse attention from competent authorities.The results of the investigation and analysis of the water showed that the water of experiment district is good for the flue-cured tobacco leaves product. |
