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.
