上海徐汇滨江绿带树种应用及优化研究

Study on Tree Species Application and Optimization in Green Belt of Shanghai Xuhui Waterfront

上海黄浦江城市滨水空间改造目标定位为打造世界级滨水公共开放空间,实现城市工业文明的绿色转型发展。发挥滨水空间的生态服务功能,需充分考虑滨水特殊立地与环境条件,进行科学的树种选择与植物配置。以黄浦江沿岸徐汇滨江公共绿地为例,调查滨江绿地树种组成,总计97种,其中乔木23种、灌木(绿篱)38种、草本地被植物36种,分属于45科80属。在分析树种生长适应性与配置特点的基础上,总结绿地景观应用形式,提出滨江绿地树种应用优化建议:(1)应用抗性树种,加强土壤改良与病虫害监测;(2)增设专类园,丰富植物应用的主题性;(3)加大“四化”树种应用,突出景观季相变化;(4)应用自然式景观配置,增加景观层次。研究将为上海城市滨水空间生态环境改造提升提供依据。

The aim of Shanghai’s urban waterfront space renovation is to create a world-class public waterfront open space,realizing the green transformation and development of urban industrial civilization.To develop the ecological service function of waterfront space,it is very important to proper tree species selection and scientific allocation and takes the unique site condition into account.This article takes the public green space along the Huangpu River in Xuhui as an example.Through a survey of the composition of green space tree species,a total of 23 species of trees,38 species of shrubs(hedgerows),and 36 species of grass belong to 45 families and 80 genera.The optimization suggestions are proposed by analyzing the growth adaptability of tree species,allocation character,and translating the landscape application forms.That is an application of resistant tree species and strengthening soil improvement and monitoring of pests and diseases,adding specialized gardens to enrich the theme of plant application,enhancing the seasonal colors,and increasing landscape levels.This study provided a basis for the ecological environment transformation and improvement of Shanghai’s urban waterfront space.
