| 摘 要： | 以哈尔滨市常见的26种主要绿化树种为研究对象,利用LCA-4型红外气体分析系统,观测了绿化树种7月的降温增湿效应.结果表明:不同树种的降温增湿效应存在差异.乔木树种中,白桦日释水总量最大(1 963.44 g/m2),樟子松最低(252.72 g/m2);小乔木树种中,文冠果的日释水总量最大(2 877.12 g/m2),野梨和稠李较低;灌木树种的日蒸腾释水总量和日蒸腾吸热总量差异较大.

| Abstract: | The primary 26 afforested tree species in City Harbin were chosen as research object and were investigated with LCA-4 Infrared Gas Analysis System.The cooling and moisturizing effect of different afforested tree species in July were compared and the results showed that some difference lied in effect of different afforested tree species.Betula platyphylla,the tree species that daily release water amount was maximum and reached 1 963.44 g/m2.And Pinus sylvestris L.var.mongolica litv was minimum and 252.72 g/m2.Among small tree species,Xanthoceras sorbifolia had maximum daily release water amount and its amount was 2 877.12 g/m2.The amount of Pyrus ussuriensis and Prunus padus were lesser.The difference between daily transpiration release water amount and absorb heat amount was significance among shrub tree species. |
