As PM2.5 affect human health, it is important to target tree planting in the role of reducing air pollution concentrations. capture capability greening trees associated with leaf morphology, while quantitative research scanty. In this paper, 25 species Beijing and Chongqing were examined by a chamber device. Groove proportion, hair, stomatal density, stomata size selected as indexes morphology. Results showed that groove proportion significantly relate quantity, no positive correlations found for hairs density. Broadleaf are conducive their rich morphology have an edge over coniferous per area. However, had larger due advantage large Significant difference existed between different Urban diverse structures complicated. Complex ecological environment may lead characteristics. Climate conditions should be considered when greening.
