摘　　要：采用田间采样和室内分析相结合的方法,对湖北省武汉、宜昌、荆门、荆州、恩施州、十堰、咸宁和黄冈共8个地区的45个主要蔬菜生产基地的pH和6种重金属（镉、汞、砷、铅、铬、铜）含量进行测定,再利用单项污染指数和综合污染指数评价方法,对土壤重金属的污染状况进行分析。结果表明,45个土壤样点pH范围为4.59~8.42,42.2%样点偏酸性;重金属含量均在《NY/T 391-2013绿色食品产地环境质量标准》限量标准以内,适宜发展绿色食品;单项污染指数表明黄冈市Cr、Cu和荆州市Cr单项污染指数超过0.7,临近警戒线;综合污染指数表明黄冈市重金属污染程度处于警戒线,其他地区均是安全的。The contents of pH and 6 kinds of heavy metals（Cd,Hg,As,Pb,Cr,Cu） on the growth of 45 major vegetable planting bases in eight urban districts of Wuhan,Yichang,Jingmen,Jingzhou,Enshi,Shiyan,Xianning and Huanggang of Hubei province were measured by field sampling and indoor analysis,and then the pollution status of heavy metals in soil was analyzed by single pollution index and comprehensive pollution index. The results showed that the pH value of 45 soil samples ranged from 4.59 to 8.42 and 42.2% were acidic. The content of heavy metal was within the limits of NY/T 391-2013 green food origin environmental quality standards,which was suitable for the development of green food. The single pollution index showed that the individual pollution index of Cr,Cu in Jingzhou city and Cr in Huanggang city exceeded 0.7,and near the warning line level. The comprehensive pollution index indicated that only the heavy metal pollution level in Huanggang was at the warning level, and other urban areas were safe.
