| 为了探讨有效调控颗粒物的居住小区植物配置方式，将居住区绿地按照位置和功能划分为小
区入口绿地、道路绿地和广场绿地3 种类型，针对每种类型的绿地探讨了不同植物配置方式对于大气颗
粒物浓度的削减效应。结果显示：乔木数量较多且通风良好的小区绿地对居住区内颗粒物削减率较高；
悬铃木（Platanus orientalis）搭配大叶黄杨（Euonymus japonicus）作为行道树对大气颗粒物的净化能力
较强，对TSP、PM10 和PM2.5 的削减率分别达18.87%、6.40% 和6.02%；与开放式广场绿地和中心绿地
相比，合理配置的半封闭式广场绿地能够更加有效地改善活动空间的空气质量。 |

| Abstract: |
| To investigate the effective plant collocation methods of controlling concentrations of particulate
matters (PM), residential green space was divided into three types, which was community portal green space, road green
space, and square green space. For each type of green space, effects of PM reduction by different plant configuration
modes were discussed. Results indicated that the PM removal percentage of residential green space with more arbor
trees and better ventilation was higher, and the purification ability of Platanus orientalis with Euonymus japonicus
used as street tree to PM was stronger, removal percentages of TSP, PM10, and PM2.5 were 18.87%, 6.40%, and 6.02%,
respectively. Compared with open square green space and central Greenland, semi-enclosed square green space with
reasonable disposal could improve the air quality of the active space more effectively. |
