Study On The Design Method Of Bio Friendly City Based On Green Network Analysis

As the urbanization process accelerates,the natural habitats in cities have been fragmented and destroyed to varying degrees due to disordered development and construction,which has brought more and more impact on the natural ecological environment.Rather than saying that humans have destroyed most of the natural environment,it is better to say that in the process of urban construction,people have eliminated nature from their lives.Based on the concern about the constantly missing bio-friendly space,thinking about how to resolve the contradiction between urban development and natural environment,in-depth discussion of the relationship between urban design and bio-friendly environment,and put forward bio-friendly urban space design strategies."Bio-friendly cities" place biological natural habitats at the forefront of design,planning,and management,recognizing the innate requirements of contact between man and nature,and the ecological and economic value of natural systems.With reference to the concepts of landscape ecology,landscape urbanism and pro-biological cities,explore new models of urban planning and construction.The bio-friendly city construction is summarized as an overall green network construction supplemented by a detailed habitat design.Through the analysis of urban green networks,bio-friendly related concepts and carding of domestic and foreign research.Based on theoretical guidance,the principles and steps of building a green network are summarized and put forward,that is,a multi-scale comprehensive construction is carried out through the "region-center-group" top-down model.By analyzing the landscape environment,combing and restoring key biological habitat spaces and biological corridors,constructing a regional green network;In the central urban area,conduct a biosecurity pattern analysis based on the research of biological habitat space,and combine the existing blue-green space to create a green vein of the urban area;Then,through a detailed study of the internal habitat points of the city group,the status of the group network connection,ring degree and built space is analyzed to build a bio-friendly green network.The overall urban design under the analysis of the green network is decomposed into three categories of "point,line and plane" and the corresponding urban construction strategy guidance methods are proposed respectively.The overall urban design under the analysis of the green network is decomposed into three categories of "point,line and plane" and the corresponding urban construction strategy guidance methods are proposed respectively.Finally,taking the overall urban design practice project in Changchun as an example,the multi-scale network construction model is used to plan the city,and the corresponding design guidance is proposed for the point,line,and surface spaces of the city’s local characteristics.Bio-friendly design emphasizes the importance of daily contact with the natural world.From the urban design guide,even small green spaces are expected to bring richer biological species and positive and healthy results.The study builds urban vitality by creating bio-friendly cities and public spaces close to nature.At last,to build the future direction of policy is discussed on the green network,for the effective development of bio-friendly city suggested.It is of great significance for urban decision makers and planners to enter bio-friendly spaces for the development of cities.
