Study On The Protection And Renewal Of Urban Wilderness Landscape

Since human society entered the industrial age,frequent human activities and the increase of urban construction have caused environmental pollution,over-exploitation of biological resources,global warming and other phenomena.The problems of habitat reduction,fragmentation and ecosystem degradation in cities have caused the rapid decline of urban biodiversity,threatening the health and stability of urban ecosystems.Due to the development of disciplines and theories such as ecological science and ecological restoration,our current views on nature are different from those of the past in many aspects.By creating the most primitive habitat patches and plant communities,the urban wilderness landscape can provide urban habitats and moving channels for ecosystems and protecting urban biodiversity.Foreign wilderness landscape design theory is more mature than our country,and there are more designs under wilderness thought,which can provide more experiences for our country’s urban wilderness landscape construction.In order to protect a small amount of urban wilderness landscape,this thesis summarizes and analyzes the existing research achievements and development direction of urban wilderness landscape,proposes that urban wilderness landscape should be built based on landscape ecology,analyzes landscape structure,dynamics and functions based on landscape ecology,and puts forward specific principles and strategies for the protection and renewal of urban wilderness landscape through in-depth study of each part,including paying more attention to biological protection functions.Comply with the natural basement of the city,rationally allocate communities,and form a multi-layer structure combining multiple plants to provide diverse habitats for organisms.At the same time,a hierarchical network of urban ecological corridors should be established to effectively protect biodiversity at different levels.The wilderness landscape of Hunhe River in Shenyang was investigated on the spot.The wilderness landscape pattern was used to evaluate the wilderness in the eastern part of Hunhe River in Shenyang,and the protection and renewal strategies of the eastern part of Hunhe River in Shenyang were put forward,which provided an ecological perspective for the protection and renewal of two types of urban wilderness landscape in China and a basis for the future protection and renewal of urban wilderness landscape.
