中文摘要 不同绿化组合比率会产生不同的降温效果,适宜的住区绿化组合比率可以营造更为舒适的居住环境。文章以长沙市典型住区为研究对象,应用ENVI-met量化评估住区不同绿化组合比率(乔灌比例为1:9、2:8、3:7、4:6、5:5、6:4、7:3)对热环境的影响,旨在获取住区最佳的绿化组合比率。结果表明,乔木所占比例越高,其对热环境的冷却效果越强,影响范围越大:当乔灌比例为7:3时,对空气温度的最大冷却值为0.18℃,对平均辐射温度最大冷却值为12.29℃,对PMV最大下降幅度为0.65;当乔灌比例为4:6时,其所带来的冷却效益最大。因此,结合考虑经济成本,建议在位于夏热冬冷气候区的住区优先采用乔灌比例为4:6的绿化组合比率。

英文摘要 Different green combination ratios produce different cooling effects,and appropriate green combination ratios in residential area could create a more comfortable living environment.The paper takes a typical residential area in Changsha to quantitatively evaluate the effects of different green combination ratios (1:9,2:8,3:7,4:6,5:5,6:4,7:3) on the thermal environment by applying ENVI-met,aimed to obtain the best green combination ratio for the residential area.The results show that,when the ratio between trees and shrubs is 7:3,the maximum cooling value on air temperature is 0.18℃,the maximum cooling value on average radiation temperature is 12.29℃,and the maximum decrease in PMV is 0.65;when the ratio is 4:6,the cooling benefit reaches the greatest.Therefore,considering the economic cost,the green combination ratio of 4:6 is preferred to be recommended for residential area located in hot-summer and cold-winter climate zones.
