摘要:道路绿化是城市绿地系统的重要组成部分,而道路植物配置的优劣将 直接影响一个城市的面貌和环境质量。本文在调查淮安市市区 30 条主要道路植 物配置现状的基础上,对道路横断面形式、植物种类、观赏效果,群落结构等进 行分析。调查记录植物 48 种,分属 35 科 41 属,其中乔木 20 种,灌木 16种,地被植物 12 种。调研结果表明,目前淮安市市区主要道路道路绿化水平和 质量均到达了较高的层次,植物配置也较为合理。但仍存在植物物种不丰富,缺 乏层次和季相变化等问题。应扩大乡土树种的应用,优化树种配置比例,丰富层 次结构,加强养护工作,从而提高淮安市道路景观效果。75842

Abstract:Road greening is an important part of urban green space system, and road plant configuration will directly affect the Portrait and the environment of the city。 According to the research of the plant land arrangement on the main 30 urban roads of Huaian City, the author analyzed the types of road cross section, plant species,ornamental effect and community structure。 There are 48 species of greening
trees noted in the investigate areas。Among them, there are 20 species of arbor,16 species of shrub, 12 species of ground cover plant。The results are as follows,at present, the greening level and quality of main road in Huaian City have obtained better achievements, and the plant disposition has also been more reasonable。But some problems have still been exposed: the plant species is not rich enough and the gradation of structure of plant arrangement is too humdrum and short of change。 In order to improve the landscaping level and promote the urban road greening in Huaian City, some countermeasure are put forward from the aspects, expanding the growth of native trees, selecting the fitting tree species, strengthening plant maintenance。
