The distribution patterns of the eight elements of Cu, Pb, Zn, Cd, Cr, Hg, As and F, which are related to urban soil environmental quality, are discussed in this paper. The Shigang area where industrial pollution is relatively weak is chosen as‘the contrast area'. By adopting the analytic method of comparison, the author assesses the soil environmental qua-lity in Wuhan city. According to the circumstances, three pollution degrees of slight, mode-rate and heavy are specified. And the minimum limit of each degree is suggested. On the ba-sis of comprehensive consideration of the contents, regional distribution and environmental conditions of the harmful elements and other factors, the urban soil in Wuhan can be divided into three zones and twelve subzones. This paper points out that the main cause of the soil environmental deterioration is related to the industrial sewage. It also provides soil geoche-mistry data for tackling the urban environmental problems.

本文论述了与城市土壤环境质量有关的Cu、Pb、Zn、Cd、Cr、Hg、As、F八种元素在土壤中的分布规律。选择了工业污染相对较小的施岗地区作为“对照区”,采用对比分析法,对市区土壤环境质量进行了评价。按污染程度分轻、中、重度污染三级,提出了不同级别污染的下限值。在综合考虑有害元素含量、区域分布及环境条件等因素基础上,把市区环境土壤分为三个区十二个小区,并指出恶化土壤环境的主要原因与工业排污有关,为城市环境综合治理提供了土壤地球化学资料。
