| Abstract: |
| Considering the greening particularity of building exterior surface,this study proposed the intermediate growing as an optimal strategy of greening the building exterior surface. The influencing factors of growth vigor and greening lifespan were analyzed and conceptual models were designed,while an experiment was conducted on the identification of intermediate growth. This study can supplement and enrich the ideas of plant cultivation and maintenance under the special urban habitats,and will provide guidance of economical and sustained model of cultivation and maintenance for expanded greening period. |
