| 摘 要： | 论述了昆明市西山土壤－菊科植物系统铜、锌分布特征。利用统计分析及吸收系数等参数，定量描述了植物、土壤中铜、锌含量水平，描述了植物对土壤中铜、锌的吸收及富集能力。结果表明：昆明西山受试菊科植物中除风毛菊外，其余１３种植物对铜表现出相对于铁的稀释作用。斑鸠菊、棉毛挖耳草、风毛菊和滇川还阳参等４种植物对锌表现出富集作用，其余１０种表现出稀释作用。

| Abstract: | Contents and distributions of Cu and Zn in soil compositae system in Xishan Hill of
Kunming were studied. Based on parameters of statistical analysis and absorption coefficients,
levels of Cu and Zn contents were described quantitatively, and abilities of absorption and
enrichment were also presented.Relative absorption coefficients of Cu in compositae except
Suassurea japonica were tested to be lower than 1, which showed cushioning effects of Cu in
the soil. Enrichment abilities of Zn were showed in Vernonia esculenta, Thylophora
yunnanensis, Suassurea japonica and Crepis rigescens, but cushioning effects of Zn were
found in other plants. |
