中文摘要：

老工业搬迁区主要道路两旁绿化带土壤由于历经老工业企业的变迁和环境的污染破坏，可在一定程度上对这一地区环境的历史变迁及重金属污染状况起到指示作用。采集沈阳铁西老工业搬迁区绿化带土壤及其绿化乔木和灌木植株样品，分析土壤中铜的总量及生物有效态含量，同时分别分析了绿化乔木（8种）和绿化灌木（6种）植株根、枝条和叶片的含铜量。结果表明，搬迁区绿化带土壤中含铜量为29．14～166．95mg／kg，显著高于沈阳市土壤铜元素的背景值；土壤有效态铜为o．23～1．72mg／kg，达到中等水平（0．3～1．0mg／kg）的占采样点总数的70．0％。数据还显示，绿化乔木和灌木对铜的蓄积能力依品种不同差异显著，同种植物不同部位（根、枝条和叶片）对铜的富集能力不同；总体上，绿化乔木植株体内含铜量的分布规律为根〉叶片〉枝条或叶片〉根〉枝条，绿化灌木植株体内含铜量的分布规律为根〉叶片〉枝条。对铜蓄积能力较强的绿化乔木为榆叶梅（Amygdalus trilobn Lindl．）、垂柳（SalixbabylonicaLinn．）、旱柳（Salixmatsudana Koidz．）和银杏（Ginkgobiloba），对铜蓄积能力较强的绿化灌木为大叶女贞（LigustrumlucidumAit．）、小叶女贞（LigustrumquihouiCarr．）和紫叶小檗（Berberis thunbergiicv．Atropurpurea）。

英文摘要：

Greenbelt soil on both sides of the mainroad in the old industrial relocation area can be an indicator in a certain extent of the regional environment change and the history of heavy metal pollution. Soil and plant （green tree and shrub） samples in green belt soil of Shenyang Tiexi Old Industrial Relocation Area （TOIRA） were collected. The total copper and the bioavailability copper in soils,and the copper in roots, stems and leaves of the landscape plants were analyzed. This investigation aims to find the contamination situation of copper in the Shenyang old industrial relocation area and to reveal the transformation of copper in the soil and green plant. Results showed that the total concentration of copper was from 29.14 mg/kg to 166.95 mg/kg in the greenbelt soil samples from the TOIRA,which was significantly higher than the soil background values in Shenyang. The concentration of available Cu were from 0.23 mg/kg to 1.72 mg/kg,and the available Cu content of 70.0% soil samples reached middle level. The difference of copper accumulation capacities among different green trees and shrubs in the roots, branches, and leaves was significant. In total, the distribution of the Cu concentration in green trees was root 〉leaf 〉branch or leaf 〉root 〉branch, while in green shrubs was root 〉leaf 〉branch. The green trees with relatively higher Cu accumulation capacity were Am ygdalus triloba Lindl., Salix babylonica Linn.,Salix matsudana Koidz. and Ginkgo biloba , and the green shrubs with relatively higher Cu accumulation capacity were Ligustrum Zucidurn Ait. ,Ligustrum quihoui Carr. and Berberis thunbergii cv. Atropurpurea.
