摘要
随着城市化的快速发展,城市绿化成为一个重要的议题。选取了种植在北京市丰台区的白蜡树作为研究对象,通过试验对比分析经特定养护和未经养护的白蜡树生态效益,并进行定量统计计算,以评估特定养护工作对白蜡树的影响。通过长时间的样本收集、数据跟踪和统计,探究了白蜡树在2种不同养护条件下的生长情况。结果表明:经过特定养护的白蜡树生长更为旺盛,在生理响应指标方面显著提升。具体为:经特定养护后白蜡树的叶面积增加20%,树高增加14.5%,冠幅增加10%,这为白蜡树在园林中的养护方法以及养护效果提供了基础数据。在此分析的基础上,进一步从土壤湿度、土壤肥力、定期修剪方面对丰台地区的白蜡树养护提出了建议。
With the rapid development of urbanization,urban greening has become an important issue.This paper selects Fraxinus chinensis Rox planted in the Fengtai District as the research object,compares and analyzes the ecological benefits of Fraxinus chinensis Rox with and without specific maintenance through experiments,and conducts quantitative statistical calculations to evaluate the impact of specific maintenance work on Fraxinus chinensis Rox.Through long-term sample collection,data tracking,and statistics,the growth of Fraxinus chinensis Rox under two different maintenance conditions was explored.The data results indicate that the specially maintained Fraxinus chinensis Rox not only grows more vigorously,but also significantly improves its environmental benefits such as reducing urban heat island effects and increasing biodiversity.Specifically,after specific maintenance,the leaf area of the Fraxinus chinensis Rox increases by 20%;the tree height increases by 14.5%,and the crown diameter increases by 10%;this provides strong basic data for the maintenance methods and effects of Fraxinus chinensis Rox in gardens.On the basis of this analysis,this paper further proposes suggestions for the maintenance of Fraxinus chinensis Rox in Fengtai District from the aspects of soil moisture,soil fertility,and regular pruning.
