摘要
为给成都市区城市绿地土壤重金属污染的预防和修复工作提供科学依据,对成都市区不同绿地土壤重金属(Cu、Zn、Pb和Cd)进行了分析调查,采用模糊综合评价法对绿地重金属污染状况进行了评价。结果表明:成都市城市绿地土壤主要的重金属污染因子为Cd,生产绿地、附属绿地符合土壤一级环境质量标准,防护绿地、公共绿地、道路绿地符合土壤二级环境质量标准。不同绿地类型重金属污染由轻到重的顺序为:生产绿地、附属绿地、防护绿地、公共绿地、道路绿地。
The actuality of four heavy metals(Cu,Zn,Cd,Pb) in urban greenland was studied.According to environmental quality standard for greenland,fuzzy mathematics model was adopted to evaluate the comprehensive greenland pollution by heavy meta1.The results indicated that the accessory greenland and the production greenland were in level one of the standard mentioned above,road Greenland,the shelter greenland and the park greenland were in level two of the standard mentioned above.The main pollutant in each greenland studied was Cd.The ranking order of the heavy metal contamination in different types of greenland was: the production greenland the accessory greenland the shelter greenland the park greenland road greenland
