Research On Urban Mountain Plant Landscape Construction Under The Guidance Of Coupling Concept

In the process of urban expansion and development,human construction activities have made urban environmental problems more and more serious,so the urban ecological environment has become the focus of research scholars.Compared with other green space,urban mountainous land is a natural patch left in the built environment of the city,and various factors in its environmental habitat are more susceptible to human construction activities,resulting in subtle changes or even inferior quality,resulting in plant community groups The structure and growth state are directly affected,so it is very important to study the plant community for the characteristics of urban mountain habitats.In the contemporary professional field,the research on the relationship between the habitat characteristics and plant communities of various spatial environment types focuses on the ecological pattern at the macro level,while there are relatively few studies on the landscape design of plant communities in different types of micro-level habitats.How to improve the correlation between plants communities and habitats,related concepts and strategies still need to be further explored.The thesis selected Nanjing Purple Mountain,Jilong Mountain,Fuzhou Mountain(Jiuhua Mountain),Gulougang,Qingliang Mountain,Wutai Mountain First Line and Qixia Mountain as the main research cases.The mountainous areas in this section are left in the urban built environment for a long time,and the habitat characteristics and plant communities formed in succession in the process of accompanying urban development have certain regional typicality and ecological value,so they are selected as the research object.The research contents and conclusions of this article mainly include:1.On the basis of combing the relevant theories,using Arc GIS analysis software,the overall habitat characteristics and spatial characteristics of typical mountainous areas are studied and analyzed,and according to the existing delineation basis,combined with the habitat characteristics and the feasibility of investigation,the The habitat types of typical mountainous areas are divided into 9 types;2.Based on the classification of habitat types,a typical sample plot survey method was used to select81 survey plots in the study mountain area.During the investigation,the habitat characteristics of the plot and the composition structure,growth status and landscape effect of the secondary vegetation community in natural succession were observed and recorded;3.Through the summary analysis of the survey data of the sample site,including the research summary of the characteristics of factors in various habitats,the evaluation and analysis of the composition structure,growth status and landscaping effect of the plant community landscape in various habitats,summarize the excellent growth and landscape The composition structure and generation mode with excellent effect,avoiding the community composition mode with poor current situation of the community and poor landscaping effect,discussed the influence of the habitat characteristics in the urban mountain environment on the composition structure and growth status of the plant community landscape,and concluded The coupling law of urban mountain habitats and plant communities in Nanjing provides references and guidance for future research and planning of urban mountain and other green space space plant community landscapes;4.Based on the above research,combined with the Lijiashan Guanyao Mountain Plant Landscape Planning Project,through the research and analysis of the project’s habitat characteristics,vegetation status and existing problems,on the basis of dividing the site habitat type,using the previous research The coupling law of mountain habitats and plant communities has been put forward,and a scientific and reasonable plant community landscape design strategy for the overall forest of Lijiashan Guanyao Mountain and various habitat types was targeted to solve the current problems of mountain environment,enhance forest phases,and promote positive vegetation.Toward succession,the strategy of transforming and upgrading the landscape from natural mountain forest around the city to urban mountain plant community was verified.This study focuses on the coupling relationship between plant community landscapes and environmental habitats in urban mountains,and discusses the composition and formation of plant communities under specific habitat conditions in the built environment,which provides theoretical support for the construction of urban mountain plant community landscapes.It has been proved by practice and practice that it has created a research idea for the realization of the coupling of urban mountain plant communities and habitat characteristics.It has important guiding significance for the design of quasi-natural plant community landscapes in various urban green space environments,and contributes to the optimization process of urban ecological environment.
