摘　　要：选取昆明市建成区内代表性的绿地,结合绿地群落特征调查分析,对绿地群落吸收和富集重金属铜、铅和锌的能力和特点进行了比较研究。结果表明:各绿地群落对重金属的吸收和富集能力与其种类构成和配置情况关系更为密切;在通过绿地对城市土壤重金属污染的治理过程中,种类选择和配置是绿地建设的关键。On researching the typical greenbelts in Kunming built-up area,the greenbelt plant community characteristics were surveyed and analysed,and the absorption and accumulation capabilities and features of the greenbelt plant community to heavy metal including Cu,Pb and Zn were comparative researched.The results showed that the absorption and accumulation capabilities of the greenbelt plant community to heavy metal was more closely related to their species constitution and allocation situation.Therefore,in the process of governing urban soil’ s heavy metal pollution through greenbelt,the key points were species selection and allocation for the construction of greenbelt.
