Researches of Street Greening Based on Plant Diversity Investigation in Wuhan

在采用抽样调查方法对武汉市区道路绿化进行调查的基础上,分析了武汉市道路绿地的物种组成、物种丰富度、频度及植物多样性组成。结果表明:武汉市区道路绿地植物种类共有64种,其中木本植物55种,占总数的85.9%。木本植物中常绿树种37种,落叶树种18种;乔木19种,灌木36种。在乔木层中,桂花、二球悬铃木、樟树、欧美杨、雪松、广玉兰等的出现频度及丰富度均较高;灌木层中出现频度及丰富度较高的植物有:红花檵木、海桐、石楠、月季、紫叶李等,并针对城市绿化现状与存在的问题提出了道路绿地建设的建议和对策。

The urban road virescence is a fundamental part of the urban green system. As the ecological corridor, the street green system has played an increasingly important role in the entire city ecological system in addition to the landscape and visual effects. Based on the research of the plant diversity of the main street in Wuhan, the paper analyses the problem as well as the valuable experience in the design of street landscape planting and tries to give some practicable methods to deal with the strategy in the road virescence of the garden city const ruction.
