成都市墙体自生植物资源调查及应用研究

Investigation and Application Research of Wall Spontaneous Plant Resources in Chengdu City

  • 摘要: 为探寻墙体自生植物与环境因子的关系,实现墙体自生植物在垂直绿化中的应用,以成都市中心城区为例,调查分析墙体自生植物的物种组成及其空间分布与湿度、坡度、海拔等墙体环境因子的关系,并筛选出适宜垂直绿化使用的墙体自生植物,在此基础上建立垂直绿化中的6种典型植物配置模式。结果表明:(1)成都市中心城区墙体共有自生植物40科71属84种,其中菊科、荨麻科和禾本科植物种类最多;(2)所选取的12个墙体环境因子中,湿度和坡度等6个环境因子对植物空间分布格局有显著影响;(3)墙体自生植物中荩草(Arthraxon hispidus)、三花莸 (Caryopteris terniflora)、紫堇(Corydalis edulis)、打破碗花花(Anemone hupehensis)等植物观赏性较强,可根据不同的墙体环境特点选择该类墙体植物进行模式化植物配置。

     

    Abstract: In order to explore the relationship between wall spontaneous plants and environmental factors, and realize the application of wall spontaneous plants in vertical greening, taking the downtown of Chengdu city as an example, the species composition of wall spontaneous plants and the relationship between wall spontaneous plants and environmental factors such as humidity, slope and altitude was investigated and analyzed, and the wall spontaneous plants suitable for vertical greening were screened out. Then six typical plant configuration modes in vertical greening were established. The results showed that there were 84 species of wall spontaneous plants belonging to 71 genera and 40 families in the walls of Chengdu central urban area, among which Compositae, Urticaceae and Grasses were the most species. Among the 12 wall environmental factors selected, 6 environmental factors such as humidity and slope, had significant effects on the spatial distribution of plants. Among the spontaneous plants on the wall, some plants such as Arthraxon hispidus, Corydalis edulis and Anemone hupehensis, etc. were highly ornamental, so these wall spontaneous plants can be selected according to the characteristics of different wall environments for model plant configuration.
