中文摘要：

空气中的颗粒物包含TSP、PM10和PM2.5,严重影响和威胁了城市人口的生活质量及健康。为了降低城市居民的健康风险，控制污染源刻不容缓。植物对环境的修复具有很大的潜力，这已得到了共识。现从叶片解剖结构、叶片表观形态、叶片平面几何形态以及叶片其它方面阐述了植物叶片滞尘能力差异。不同绿化树种对颗粒物的吸附净化作用不同，通过比较不同城市绿化树种对大气中颗粒物的净化能力，来探索经济高效的环境治理方法，这在当今显得尤为重要。

英文摘要：

The inhalable particles in the air,including TSP,PM10 and PM2.5 are major threat to living quality and health of urban people. To reduce healthy risk of urban people,controlling pollutant source is a matter of utmost urgency. Plant remedy has great potential in environmental rehabilitation,which has already arrived at a consensus. This paper depicted the general situation about dust-retention ability of plants leaf from the following four aspects： classification of leaf anatomical, classification of leaf morphology, geometry classification of leaf morphology,other classification closely related to leaf morphology. To different species, adsorption to total suspending particles would be different. Thus, in order to discover economical and efficient methods of environmental improvement in the present, it is of great importance in comparing the purification capacity of urban green plants in different cities.
