本文对不同行道绿化树、蔓藤攀缘植物、草坪绿地温、湿度效应进行了测定，结果表明：夏季三种乔木行道绿化树种较未绿化空旷地日平均地表气温降低２．２℃—３．２℃，最高降温达３．８℃；二种蔓藤攀缘植物地表日平均降低温度２．７℃—３．９℃，最高降温达４．３℃；草坪绿地和行道绿化树荫下水泥路面较空旷裸露水泥路面地表温度分别平均降低９．８℃和８．５℃，最高降温达１５．６℃；乔木行道绿化树和蔓藤攀缘植物较未绿化空旷地日平均地表温度增加１２．９％—１４．７％和１７．５％。同时还对不同绿化树木种类、形态特征及郁闭度等影响降温增湿效应的因素进行了分析和探讨。
In this paper, the temperature and humidity effects of greening trees, creeper plants and lawn greens in different roadsides were measured. The results showed that the average daily surface air temperature of three greenway tree species in summer was 2.2 ℃ -3.2 ℃ and the maximum temperature drop reached 3.8 ℃. The average daily temperature drop of two creeper plants was 2.7 ℃ -3.9 ℃, and the highest temperature drop reached 4.3 ℃. The green pavement of cement lawn The average surface temperature of bare bare concrete pavement decreased by 9.8 ℃ and 8.5 ℃ on average, and the maximum temperature drop reached 15.6 ℃. The average daily surface temperature of green trees and creeper plants in creeping trees increased by 12.9% -14.7% and 17.5%. At the same time, the factors affecting the effect of cooling and humidification on the species, morphological characteristics and canopy density of different greening trees were analyzed and discussed.
