The Research On Green Space Planning Strategy Of Shangluo City Based On Climate Adaptability

The increase of urban climate sensitivity will affect urban environmental quality and threaten urban ecological security.The urban green space has the function of optimizing the ecological pattern,and the green space network oriented by climate adaptation can effectively improve the quality of the ecological environment and alleviate environmental problems during urban construction.Shangluo is located in the transitional zone between the northern subtropical climate and the warm temperate zone.The temperature in the central city shows an obvious upward trend,and there is a phenomenon of high local heat load and poor ventilation.The thesis takes Shangluo urban green space as the research object,aiming at the sensitive problem of urban climate,explores its planning response to climate problems from the level of urban green space construction,and creates an urban environment with appropriate temperature and smooth ventilation,which has important enlightenment for the construction work of shangluo city with climate adaptability.By combing the theory and practice of urban climate analysis of related specialties at home and abroad,the thesis confirms the urban climate analysis method of Shangluo City,that is,referring to the method of urban climate analysis map,taking into account the effect of atmospheric climate background and urban construction on the urban climate of Shangluo City comprehensively,and using the tools of GIS,it clarifies the current situation of the climate environment with high heat load,weak ventilation and high climate sensitivity in the planning area.The thesis uses the field research method to collect and collate relevant materials,analyzes the green space construction of Shangluo City from the perspectives of urban green space components,spatial layout and quality,studies the coupling and coordination relationship between various elements of green space and climate,and finds the green space of Shangluo city to the city.The effect of the heat load environment is not significant,the adjustment effect on the wind environment is not prominent,and the connectivity between the various elements needs to be improved.In view of the coupling status and main climatic problems of green space and urban climate in Shangluo central city,the thesis proposes urban green space planning strategies to adapt to climate change from three aspects: alleviating urban heat load,enhancing ventilation effect and promoting linkages among various elements.The thesis takes the humidification and cooling effect as the premise to control the urban green space area,improve the green space quality,enrich the green space form,and improve the comprehensiveness and flexibility of the urban green space to adapt to the climate.In order to solve the problem of poor ventilation inside the city,the thesis relies on the linear green space to determine the grid layout of the corridor system.The green heart is coordinated with the scatter layout to improve the composite layout of “Green Heart – Green Corridor”.The thesis based on the effect of climate regulation,divides the urban green space level,clarifies the intersections and contact channels of corridors at all levels,and constructs a perfect urban green space network structure.Based on the coupling analysis of Shangluo urban green space and urban climate,the thesis constructs a composite urban green space framework of "Green Heart-Green Corridor",and puts forward the planning strategies of guiding and controlling the scale of green space,Optimizing Ventilation corridor and constructing green space network.The thesis hopes through this study to expand the research perspective and content of Shangluo urban green space planning,and provide reference for the research and planning of green space in ecologically sensitive areas.
