Research On Green Space Layout Method In Forest Urban Planning

With the advancement of urbanization,the urban environmental problems have increasingly attracted people's attention.The state has successively proposed the construction of garden cities,ecological cities,forest cities,park cities and other slogans,with the aim of improving ecological destruction and creating a good living environment..As an important part of green space,urban forests play an important role in improving environmental quality.Based on the planning of forest cities,this paper studies the green space layout method of forests,enhances the rationality of green space layout,and achieves sustainable development.Based on the basic research,this paper clarifies the relevant theories and general situation of forest city and green space,discusses the layout method of forest green space through the basis of in-depth study,and puts forward five principles of coordination,adaptation,urban and rural integration,local conditions,index control and dynamic control.The main idea of green space layout is to deal with the relationship between development and protection,to find the smart density of urban development,and to guide the rational layout of green space through index control.Summarize the basic process of green space layout,sort out the key elements of the natural environment,social economy,history and culture,and connect them with the related superior planning.Guided by the problem,formulate reasonable planning goals and concepts,and build a green space ecological network in the built-up area and the construction area.In the built-up area,different forms of forest green space such as point,ring,net,wedge and belt are laid out to enhance the systemic and continuity of urban green space;In the construction area,the principle of"plaque-corridor-matrix" is applied to layout the green space,to strengthen ecological exchanges between regions.Combined with case analysis,the four strategies of green space layout are proposed to better guide the construction of forest green space.Using the previous research conclusions to guide the practice of provincial forest city planning in Fengyang County,identify the green space elements that have an important impact on Fengyang ecological security,and identify the problems and deficiencies through the analysis of the forest green space in Fengyang County,then combined with the ecological security pattern and cultural characteristics of Fengyang,making the forest green space and other elements coordinately coupled.Formulating construction goals and planning concepts at the macro level;Constructing a forest ecological network at the meso level,with the forest ecosystem structure of "landscapes,green corridors,forests and waters,and urban and rural integration",construction area form a forest ecosystem structure that is "one core,one valley,three districts and five corridors,green veins and beads";The built-up area will create the urban forest ecosystem pattern features of "Green Heart Inlay City,Green Surrounding City,Green Water Show City,Green Garden City",forming the urban forest ecological network that is "one mountain,one district,three rings,multiple corridors,multiple blue and green intertwined";Control and guidance of indicators at the micro level to improve the green space pattern of forests in Fengyang County...
