摘　　要：通过对南京市区的各功能区植物叶片中的氮、硫、铅元素含量的分析,研究了植物大气环境污染指数,探讨了植物叶片的氮、硫、铅元素含量的季节变化,以及与城市大气环境污染之间的关系。结果表明,植物叶片中,硫、铅元素的含量随季节变化不断增加,而氮元素含量相应减少;各功能区的硫、铅元素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的质量状况。By analyzing the content of nitrogen, sulfur and lead in leaves of plants in every function district of Nanjing city, the index of air environment pollution of plants was studied, and the relationship between seasonal changes of the content of nitrogen, sulfur and lead in leaves of plants and air environment pollution of the city was discussed, The results indicated that while the content of nitrogen decreased relatively, the contents of sulfur and lead of plant leaves in every function district were distinctly higher than those of clean control. The air quality could he evaluated hv the plant nollution index.
