快速城镇化背景下行道树的生境胁迫及其适应性设计
|
摘要
快速城镇化进程对行道树生境造成巨大的威胁,严重制约了行道树的生长及其功能发挥,然而目前关于行道树生境的研究成果较为鲜见。本文通过对福州市5个市辖区72条不同功能区的道路进行调查,发现行道树生境存在空间不足、透水度差、地面覆盖结构简单等生境胁迫问题。在此基础上,从城市快速扩张、设计考虑不周、管护方式欠妥及部门管理权责不清等4个方面探讨其产生的原因,并提出了适应行道树生境的道路规划设计要点,旨在为福州市及其他地区道路规划设计以及行道树种植提供有益借鉴。
The rapid urbanization process poses a great threat to the roadside tree habitat,seriously restricting the growth and function of the roadside tree.However,the current research results on the roadside tree habitat are relatively rare.Based on the investigation of 72 roads in different functional areas of five municipalities in Fuzhou City,this paper found that there were some habitat stresses such as insufficient space,poor permeability and simple ground cover structure in the habitat of street trees.On this basis,the causes were discussed from four aspects:rapid urban expansion,improper design,inappropriate management and unclear responsibilities of departments,and the key points of road planning and design adapted to the habitat of street trees were put forward,aiming at providing useful reference for road planning and design and planting of street trees in Fuzhou City and other areas.
