摘要

高密度城市交通流量的大幅增加，使得城市街区颗粒物污染问题日益严峻。街道绿化作为城市景观的重要组成，其植物形态参数特征对街区空气质量产生重要影响。本文以广州市某街区为研究对象，首先利用实测数据验证ENVI-met软件模拟街区尺度PM

2.5

典型颗粒物分布特性的精度，进而对案例区域街道两侧植物的多种形态参数组合进行建模及数值模拟。ENVI-met软件的验证结果表明该模型对于模拟高密度城市街区交通源PM

2.5

分布具有一定适用性。多组植物形态模拟结果显示：行道树高度建议在10 m左右，能够有效降低交通源PM

2.5

质量浓度，结合相关规范，建议树干高度设置为3~5 m，冠幅为5~7 m。

Abstract

With the substantial increase of traffic flow in high-density cities

particulate matter pollution has been a serious problem in urban blocks. As an important composition of urban landscape

its plant morphological parameters have an important impact on air quality of street. Taking a block in Guangzhou as the research subject while using field monitoring data

the accuracy of ENVI-met software in dealing with block scale PM

2.5

simulation characteristics is verified. Then

the combination of various morphological parameters of plants on both sides of the street in the case area is modeled and numerically simulated. The result of ENVI-met shows that the model is suitable for simula

ting the traffic source PM

2.5

of high-density urban blocks. The simulation results of several groups of plant morphology show that the height of street trees is recommended to be about 10 m

which can effectively reduce the PM

2.5

of traffic source concentration. In combination with relevant specifications

it is recommended to set the trunk height as 3~5 m and the crown width as 5~7 m.
