摘要
本文选取杭州市内两条道路,共计218株行道树为研究对象,通过测量每株行道树的胸径、冠幅、树高,并观测与树木健康相关的指标,对树木健康度进行评分,然后依据上述行道树所采用的树池形式、树木种植方位对其进行分组,运用SPSS统计分析软件,对树池形式、种植方位与行道树的胸径、冠幅、树高、树木健康度进行相关性分析。结果表明,行道树的树池形式对树木生长的各项参数均存在显著的相关性,条带式树池的行道树明显优于单坑式树池的行道树;而种植方位则主要在冠幅上存在一定的相关性,其他参数并不明显。因此,本文得出城市行道树生长状况的决定性因素在于树池形式的结论,建议在道路条件许可的情况下,加大条带式树池的应用力度,促进行道树的健康生长,以便为城市道路创造更高效的道路绿化生态效益。
This paper selects a total of 218 street trees on two roads in Hangzhou as the research object.By measuring the diameter at breast height,crown breadth and height of each tree,the tree health is scored by observing the indicators related to tree health.Then the trees are grouped according to the tree pool form and tree planting orientation adopted by the above-mentioned street trees,and SPSS statistical analysis software is used to analyze the correlation between the tree pool form,planting orientation and the breast diameter,crown width,tree height,and tree health of the street trees.The results show that the tree pool form of street trees has a significant correlation with the various parameters of tree growth.The street trees of the strip-type tree pool are obviously better than the street trees of the single-pit type tree pool,and the planting direction mainly exists in the crown breadth while the other parameters are not obvious.Therefore,this paper draws the conclusion that the decisive factor in the growth of urban street trees lies in the form of tree pool.It is recommended that if the road conditions permit,the application of strip-type tree pool should be promoted to promote the healthy growth of street trees,so as to generate more efficient city road greening ecological benefits.
