摘　　要：文章通过对广州市区植物叶片中重金属元素含量的分析 ,研究了植物大气环境污染指数 ,探讨了植物叶片重金属元素含量与城市大气环境污染之间的关系。结果表明 ,植物叶片中Cu、Pb、Cd、Cr元素污染都较严重 ,在重污染区这些元素的含量明显高于清洁对照区 ;用植物污染指数可以综合评价大气环境质量状况 ;利用植物叶片内的重金属含量变化 。In this paper, the contents of heavy metals in leaves of plants in Guangzhou region were measured, and index of air environment pollution of plants was studied with a discussion of the relationship between the contents of heavy metal elements of leaves and air environment pollution. The results indicated that plants are seriously polluted by Cu,Pb,Cd,Cr and the contents of heavy metal elements in heavy pollution area are higher than that in clean control place, the index of air pollution of plants can be used for evaluating air quality and classification assessment of air quality. Therefore, it has been proved that this method is a good way in evaluating air pollution using contents of heavy metals in leaves of plants.
