Urban Green Infrastructure Planning And Design Based On Resilience Landscape Theory

With the global warming,extreme weather in the human built environment,rapid expansion of urbanization makes the fragile urban ecosystem more vulnerable to sudden natural disasters and their secondary disasters,then build disaster-adaptation urban landscapes have become the focus of research.However,due to the particularity of urban development,the construction of green infrastructure is difficult to advance,such as the rapid development of urban development and the confusion of land use caused by the lack of convergence of planning departments;the tightening of land resources has led to the planned use of green facilities by other types of land;The change of the strategy in the early and late stages led to the inability of the green infrastructure network to connect into the system,and the fragmentation of the urban green space.These problems all hindered the construction of the urban resilience system.While the strategies of sponge city,rain garden and low impact development have achieved results in the main demonstration areas,they have not been promoted in cities and towns across the country,and they are more instructive in building areas.The reference significance of urban areas is very limited.In response to these problems,foreign countries have heated discussions on the resilience landscape in recent years.The resilience landscape aims to integrate the artificial environment into the natural ecosystem,and regard the disturbance of nature as part of the landscape,rather than against nature.Maintain dynamic balance in the disturbance of nature,improve the diversity,stability and connectivity of the site to adapt to frequent disasters.All of this coincides with the connotation of green infrastructure.The green infrastructure also advocates the integrity and connectivity of the site.It is like a large network connecting the artificial environment with the natural system.Any local environmental change can pass.The network allocates the material energy of other nodes to relieve the pressure.Any local node failure has other node replacements with the same function.The entire green infrastructure network is very calm in response to external environmental changes.In this context,the author focuses on the urban green infrastructure,an important part of the urban ecosystem,and uses green infrastructure as a theoretical basis to study how to integrate the concept of resilient landscape into urban green infrastructure planning and design to improve urban ecology.The system's ability to adapt to disasters.Firstly,the concept,origin and composition of the tough landscape and green infrastructure are analyzed to find out the point of convergence between the two.Secondly,the feasibility and necessity of the combination of the two are analyzed,and the two are listed in nature.Forms,functional composites,environmental adaptation,network level and other aspects of the combination,and then combined with relevant cases at home and abroad,through the analysis of the case to further argue the arguments,and summed up the principles and specifics of the resilience landscape in the construction of green infrastructure Application methods and implementation experience worthy of reference,in order to provide suggestions for the construction of resilient green infrastructure in China.Finally,under the premise of a large number of review studies,feasibility analysis and application methods analysis,combined with the actual situation in China,the case design practice of Xiaolan Town in Zhongshan City is used as a research object to provide case results for the construction of resilient green infrastructure.For the later researchers to carry out related research.
