- 摘要:
- 以苏州市紫薇（Lagerstroemia indica L.）、桂花（Osmanthus fragrans (Thunb.)Lour.）、紫叶李（Prunus cerasifera Ehrh.‘Atropurpurea’ Jacq.）、日本晚樱（Prunus lannesiana Wils.）和腊梅（Chimonanthus praecox (L.) Link.）等5种常见的群植小乔木为研究对象，研究其对降温增湿效应和对PM2.5的消减效应。结果表明：5种群植小乔木中，紫薇和桂花的降温效应相对明显，日本晚樱和紫薇的增湿效应明显；紫薇对PM2.5消减效应最为明显；5种群植小乔木综合降温增湿效应由大到小依次为：紫薇＞日本晚樱＞紫叶李＞桂花＞腊梅。其降温增湿效应与PM2.5消减效应的相关性分析表明，群落内部的降温增湿效应与PM2.5消减效应显著相关；该研究结果为植物配置结构的优化及城市生态环境的改善提供了科学依据及可能的途径。
- Abstract:
- Taking 5 typical small arbor communities，Lagerstroemia indica L.，Osmanthus fragrans (Thunb.) Lour.，Prunus cerasifera Ehrh.‘Atropurpurea’ Jacq., Prunus lannesiana Wils.and Chimonanthus praecox (L.) Link.in Suzhou city as research objects，effect of temperature-decreasing and humidity-increasing，and subduction effect on PM2.5 concentrations were studied.The results showed that the temperature-decreasing effect of Lagerstroemia indica L.and Osmanthus fragrans (Thunb.) Lour.were relatively obvious，the humidity-increasing effect of Prunus lannesiana Wils. and Lagerstroemia indica L.were obvious；meanwhile the subduction effect of Lagerstroemia indica L.on PM2.5 concentrations was the most obvious；the capacity order of their cooling and humidification were Lagerstroemia indica L.> Prunus lannesiana Wils.>Prunus cerasifera Ehrh.‘Atropurpurea’ Jacq.>Osmanthus fragrans (Thunb.) Lour.> Chimonanthus praecox (L.) Link.. The correlation analysis showed that there was a significant correlation between temperature-decreasing and humidity-increasing effect and the subduction effect at center of the communities.The result could provide the scientific basis and possible ways for optimizing plant configuration and improving urban ecological environment.
