摘　　要：以2001年实施的国家无公害蔬菜产地土壤环境质量标准为依据,对1999年和2000年长春市申报的城区3600hm^2蔬菜产地的土壤环境质量进行了检测与评价。结果表明:拟申报无公害蔬菜产地的土壤环境质量良好,未受污染,土壤中Hg、Cd、Pb、As、Cr含量处于环境背景值范围之内,完全符合评价标准要求,土壤环境适宜发展无公害蔬菜。Based on the environmental quality standard of free-pollution vegetable producing area, which was carried out in 2001, soil environmental quality in 3 600 hm2 vegetable producing area was declared in 1999 and 2000. The conclusion indicates that these areas' environmental quality is good. They haven't been polluted and the contents of Hg, Cd, Pb, As and Cr in the soil are within the range of environmental background values, which means they meet the standard request. Therefore, the land in these assessed areas are suitable to be developed to produce free-pollution vegetables.
