摘要/Abstract

摘要： 城市道路绿地对局地污染物扩散的影响研究近年来比较活跃,获得了大量研究结果,但因缺乏总结梳理,尚难切实指导城市绿地建设实践。本文对道路及绿带类型进行归类,以实地监测和数值模拟两种常用方法为分类前提,对相关研究涉及的污染物浓度指标、植物特征因子及其他影响因子进行系统回顾,总结了道路绿地对局地污染扩散的影响规律,进而指出未来应在拓展研究对象、综合考虑多种生态过程、融合两种基本方法、提高数据的精度和丰富度等方面加强研究。

Abstract: In recent years, the research on the effects of urban road green space on local pollutant dispersion has been quite active, with mounting empirical results. Due to the lack of summary and arrangement, however, it is difficult to effectively guide the practice of urban green space construction. In this review, the road and green belt research objects were classified. Based on two common methods of field measurement and numerical simulation, the pollutant concentration index, vegetation characters and other influencing factors involved in relevant research were systematically reviewed. The effects of road green space on dispersion of local pollution were summarized. Future research should be strengthened in the aspects of expanding research objects, comprehensively considering multiple ecological processes, integrating two basic methods, and improving the accuracy and richness of data.

Key words: road, street canyon, dispersion, numerical simulation, field measurement, pollutant concentration, vegetation character
