摘要： 以城市森林生态系统常绿树种为对象，测定了油松（Pinus tabuliformis）和侧柏（Platycladus orientalis）叶片对大气污染物（SO2、Cl2）和土壤重金属污染物（Cu、Zn、As、Hg和Pb、Cd和Cr）的吸滞作用与富集作用。结果表明：油松和侧柏具有较强吸滞污染物的作用，对污染物的吸滞能力受环境污染程度、不同生长季节的污染元素种类等因素的影响。其中，油松在秋季对S、Cu、Zn、Pb和Hg具有较高的吸附能力，针叶中S、Cu、Zn、Pb和Hg含量平均值分别为2158.75、6.31、31.46、4.05 mg·kg-1和0.08 mg·kg-1；侧柏在秋季对Cu、Zn、Hg和Cd具有较高的吸附能力，叶片中Cu、Zn、Hg、Cd含量平均值分别为4.47、22.47、0.09 mg·kg-1和0.20 mg·kg-1；在不同立地条件下，油松和侧柏对污染物的吸滞与富集量有所差异，其中在土壤污染较重的石景山松林园样地，油松对大气污染物SO2有较强的吸附能力，侧柏则表现出对Cl2有较强的吸附能力。对重金属污染物而言，油松和侧柏对Cu、Pb、Cr和As有较高的富集作用。

Abstract: Evergreen species of Chinese pine (Pinus tabuliformis) and oriental arborvitae (Platycladus orientalis) in the urban forest ecosystem were selected in order to determine the absorption and concentration effects of leaves to atmospheric pollutants (SO2, Cl2) and heavy metal pollutants (Cu, Zn, As, Hg, Pb, Cd and Cr) in soil. The results indicate that two evergreen species are of stronger absorption ability to pollutants. The absorption ability is influenced by the environmental pollution extent and types of pollutants in the different seasons. Chinese pine (Pinus tabuliformis) and oriental arborvitae (Platycladus orientalis) have a higher absorption ability to S, Cu, Zn, Pb, Hg and to Cu, Zn, Hg, Cd in autumn, and their mean concentrations of leaves are 2158.75, 6.31, 31.46, 4.05, 0.08 mg·kg-1 and 4.47, 22.47, 0.09 mg·kg-1,0.20 mg·kg-1, respectively. The absorption and concentration abilities of the two evergreen species to pollutants are different under the different habitat conditions. In pine forest sample site of Shijingshan with serious soil pollution, Chinese pine (Pinus tabuliformis) and oriental arborvitae (Platycladus orientalis) can absorb largely SO2 and Cl2, respectively. For the heavy metal pollution, the concentration effects of two evergreen species to Cu, Pb, Cr and As are high.
