摘　　要：城市森林是城市的后花园,为城市发展提供显著的生态效益。以国内外叶面颗粒物重金属和多环芳烃(PAHs)相关的研究文献为依据,综合分析了城市化程度、植被覆盖程度、植物种类、气候因素、城市热量来源等因子对城市叶面颗粒物重金属和PAHs含量的影响,全面解析了叶面颗粒物重金属和PAHs的主要来源如化石燃料、煤炭及生物质燃烧、工业排放以及道路降尘等,总体剖析了其生态风险及健康风险的评价方法,并对叶面颗粒物重金属和PAHs的综合防治进行了展望,以期为城市污染防治提供依据。Urban forest is the back garden of city,which provides remarkable ecological benefits for urban development.Based on the research literatures of heavy metals and polycyclic aromatic hydrocarbons(PAHs)in urban foliar particulates at home and abroad,this paper comprehensively analyzed the influence of urbanization level,vegetation coverage,plant species,climate factors,urban heat source and other factors on urban foliar particles content of heavy metals and PAHs,and aggregate resolved the main sources of foliar particles heavy metals and PAHs,such as the burning of fossil fuels,coal and biomass combustion,industrial emissions and road dust,and the overall analysis of its ecological risk and health risk evaluation method.The comprehensive pollution control of heavy metals and PAHs in foliar particulate matter were prospected in order to provide basis for urban pollution control.
