摘 要
本研究旨在探究城市园林植物对空气污染物的吸附能力，分析不同部位和种类植物叶片中有害气体的吸附能力并比较其差异。结果发现，城市园林植物对多种有害气体具有不同程度的吸附能力，其中NO2和SO2的吸附能力最强。不同种类植物对同一种有害气体的吸附能力存在差异，叶面积较大的树种吸附能力更好，而草坪植物的吸附能力最弱。研究结果表明园林植物在城市空气污染治理中具有一定的作用，且通过植物组合的优化可以有效提高园林植物的吸附效果。因此，城市规划和管理应注重植物资源的合理配置和管理，以提高城市空气质量和环境可持续性。此外，本研究为园林植物在城市环境中的应用提供了科学依据，也提供了一些参考数据和方法，为解决城市污染问题提供了新思路和方法。结果表明，城市园林植物可作为一种有效的城市空气污染治理手段，优化植物组合可有效提高园林植物的吸附效果。

STUDY ON ADSORPTION CAPACITY OF GARDEN PLANTS TO URBAN AIR POLLUTANTS
ABSTRACT
The purpose of this study was to explore the adsorption capacity of urban garden plants to air pollutants, analyze the adsorption capacity of harmful gases in the leaves of different parts and species of plants, and compare the differences. The results showed that urban garden plants had different adsorption capacities to various harmful gases, and the adsorption capacities of NO2 and SO2 were the strongest. The adsorption capacity of different kinds of plants to the same harmful gas is different, the adsorption capacity of tree species with larger leaf area is better, while the adsorption capacity of lawn plants is the weakest. The results show that garden plants play a certain role in urban air pollution control, and the adsorption effect of garden plants can be effectively improved through the optimization of plant combination. Therefore, urban planning and management should focus on the rational allocation and management of plant resources to improve urban air quality and environmental sustainability. In addition, this study provides a scientific basis for the application of garden plants in urban environment, as well as some reference data and methods, and provides new ideas and methods for solving urban pollution problems. The results show that urban garden plants can be used as an effective means to control urban air pollution, and optimizing the plant combination can effectively improve the adsorption effect of garden plants.
