本文描述了天津市8个景观单元土壤剖面中重金属污染物的垂直分布特征，并对污染原因进行了探讨。分析结果表明，重金属在土壤剖面上存在差异。城市附近土壤剖面Cd、Hg、Cu、Pb污染较重，污染集中在0~50 cm土层。污水的土地灌溉和污泥的土地利用及城市扬尘是造成重金属污染的主要原因。
The paper describes vertical distribution characteristics of heavy metal pollutants in soil profile for 8 landscape units in Tianjin and discusses the causes for pollution. Analytical results show that the heavy metals are varied with soil profiles. Soil profile near the city is heavierly polluted by Cd, Hg, Cu and Pb that are concentrated in a layer 0～50 cm thick. Land irragation of waste water and application of sludge to land and city dust pricipitation are the main causes for the heavy metal pollution.
