城市作为人居集中的特殊生态地域,要求城市绿化植物选择符合城市生态和人的需要。长期以来,许多城市绿化植物选择存在一些缺陷,其中比较典型的问题是,在实现城市绿化生物多样性的过程中,对乡土植物的应用重视不足,为实现城市植物多样性,盲目引种,导致养护成本过高、城市生态系统单一而脆弱。此外,城市绿化风格缺乏地域特点。 The city, as a special ecological area with concentrated human settlements, requires that the selection of urban greenery meets the needs of urban ecology and human beings. For a long time, many urban greening plant selection has some defects. The typical problem is that in the process of urban greening biodiversity, the application of native plants is not enough. In order to realize the urban plant diversity, blind introduction and maintenance Costs are high and urban ecosystems are single and fragile. In addition, the urban greening style lacks geographical features.
