摘　　要：采用田间取样和室内分析相结合的方法,对武汉市江夏区、洪山区、蔡甸区、东西湖区、新洲区的24个蔬菜基地土壤的pH值、EC值、有机质含量,以及铜(Cu)、锌(Zn)、镉(Cd)和铅(Pb)4种重金属含量进行调查和分析。试验结果显示,24个土壤样点重金属含量均在GB 15618-1995土壤环境质量标准限量标准以内,为蔬菜安全生产基地。但从无公害蔬菜生产角度出发,应采取多种措施控制重金属污染源,对土壤酸化严重的部分蔬菜基地予以高度重视。In the paper,we sampled soils from 24 vegetable production bases in districts of Jiangxia,Hongshan,Caidian,Dongxihu and Xinzhou of Wuhan,and analyzed their pH value,EC value,organic matter content and the heavy metal contents including Cu,Zn,Cd and Pb.The results showed that the heavy metal contents of the 24 samples were lower than the upper limit of National Environmental Standard of Soil（GB 15618-1995）,indicating that the 24 suburb bases in Wuhan were safe for vegetable production.However,in order to produce pollution-free vegetables,we should take various measures to control pollution sources of heavy metals,and pay more attention to the vegetable production bases with the soils acidulated seriously.
