摘要
为研究郑州市行道树遮荫及UVB屏蔽效果,选取了20种行道树进行调查.结果表明,不同树种之间遮荫效果及UVB屏蔽效果均存在显著性差异.遮荫效果和UVB屏蔽效果最好的均为悬铃木,分别为6.76和95.40,最差的均为梓树,分别为0.35和15.20.冠幅和胸径与遮荫效果和UVB屏蔽效果均呈显著正相关关系,树高和枝下高与两者相关性均不显著.遮荫效果与UVB屏蔽效果也呈显著正相关.综合遮荫效果和UVB屏蔽效果,表现较好的为悬铃木、银杏和白蜡.
In order to study the shading effect and UVB shielding effect of street tree in Zhengzhou,20 kinds of street trees were selected for investigation. The results showed that there were significant differences in shading effect and UVB shielding effect among different tree species. The shading effect and UVB shielding effect of Platanus were the best,which were 6.76 and 95.40 respectively. The shading effect and UVB shielding effect of Catalpa ovata were the worst,which were 0.35 and 15.20 respectively. Crown width and DBH had a significant positive correlation with shading effect and UVB shielding effect,while tree height and branch height had no significant correlation with the both. There was also a significant positive correlation between shading effect and UVB shielding effect. Combined with shading effect and UVB shielding effect,the better performances of Platanus,Ginkgo biloba and Fraxinus chinensis were better than the others.
