| Since the beginning of the 21 st century,with the development of my country’s urbanization process,the urban population has been highly concentrated,which has brought severe challenges to urban biodiversity.In high-density cities,ground green areas are limited,and there are few green spaces that can be planned,and the conditions for biodiversity optimization are more stringent.Green roofs are essentially artificially constructed urban habitats.It can help cities increase biodiversity and make cities more sustainable by scientifically adjusting soil composition and reasonably matching plant communities.However,in the current research on roof greening habitats at home and abroad,biodiversity research only accounts for a small part of the research work,and lacks the viewpoint of the needs of habitats.Therefore,this article studies the construction strategy of rooftop greening habitat landscape from two perspectives of human use demand and biological habitat demand.The research of this article mainly includes the following five aspects:(1)Research on the related theories of roof greening habitats,in-depth exploration of the ecological value of building roof greening,exploring effective methods for classifying roof greening habitat types based on sunlight factors,and putting forward the viewpoint of urban greening habitat construction.The following are general roof greening habitats Optimal design strategy provides a basis.(2)Through field surveys on the roof greening of Tianjie Street in Longhu West City of Chengdu City and the roof greening of Chengdu Joy City,the current roof greening design lacks the specific manifestations of the biological habitat perspective,and the current roof greening design is proposed.Meet the needs of human use.At the same time,to a large extent,through the discussion of the living habits of indicator species,the analysis of the biological habitat requirements of green roofs provides a more practical background for future strategic research.(3)A qualitative analysis of common factors affecting human use demand and biological habitat demand is carried out,and how common influencing factors affect human use demand and the relationship between biological habitat demand and common influencing factors are discussed and analyzed.The strategies presented later provide a qualitative basis.(4)Starting from the common influencing factors,starting from the three aspects of human and biological space utilization,plant configuration and roof greening landscape elements,the main ideas of roof greening habitat optimization are proposed,and more practical guidance strategies are proposed..(5)The optimization strategy of rooftop greening landscape habitat construction based on human use needs and biological habitat requirements discussed in the previous article is applied to the rooftop greening design of Yintai Center in Chengdu Suburban Park Community to realize the practical application of the project.The strategy proposed in the previous article.evidence. |
