| The deterioration of climate and the sharp decline of biodiversity are ecological problems that people all over the world are facing.Under the background of the construction of ecological civilization in China,in order to protect urban biodiversity,curb urban sprawl and regulate the urban heat island effect,Guangzhou has prepared the overall planning of ecological corridors and the guidelines for the planning and construction of ecological corridors.Guanggang Park,the central green space of Guanggang new town,is located on the cluster ecological corridor.Biodiversity protection is the most important function of the ecological corridor.As a post-industrial landscape park,the requirements for ecological design of the park have been raised to an unprecedented level.But,the existing ecological design theory and practice of the post-industrial landscape park fail to match the requirements for biodiversity protection of the ecological corridor construction.There is still room for discussion on the ecological landscape planning and design mode of Guanggang park.Through ecological design,Guanggang Park in Liwan District revitalizes this industrial wasteland.It not only protects Industrial Relics and provides high-quality urban open space,but also realizes biodiversity protection and has the additional function of natural education.Based on the ecological construction conditions of Guanggang Park and the existing biodiversity planning and design theory,this thesis focuses on the biodiversity design of Guanggang park.This thesis is mainly divided into five parts.The first part is the basic theory part,which carries out the basic theoretical research on the ecological restoration and biodiversity enhancement of Guanggang Park in three aspects: restoration ecology,urban biodiversity and post-industrial landscape park.The second part is the research on the practice of ecological design of post-industrial landscape park,which mainly discusses the case analysis and mode evolution.By combing the realistic background,guiding theory and main characteristics of post-industrial landscape park in different periods,the development trend of mode evolution is obtained,and the future development mode of "bio friendly mode" is deduced.The third part is the evaluation of the ecological construction conditions of Guanggang Park,which evaluates the site conditions according to the general situation of it,animal and plant resources,potential soil pollution,landscape visual impact and microclimate characteristics.The fourth part is the ecological landscape planning and design strategy of Guanggang park.In combination with the development trend of "bio friendly mode" and the ecological construction conditions of Guanggang Park,it puts forward principles,concepts,objectives,strategies and corresponding guidelines for the ecological landscape planning and design of Guanggang park.The fifth part is the biodiversity design of Guanggang park.In order to implement the main purpose of biodiversity protection of the ecological corridor,based on the construction conditions and animal and plant resources of the site,the animal food chain suitable for Guanggang park is designed,and the key species among them are selected as the target species for in-depth habitat space design.The results show that: 1)the evolution of ecological landscape design of post-industrial landscape park can be divided into three stages: environmental restoration mode,rural landscape mode and natural landscape mode.Combined with the upsurge of biodiversity protection and the development of ecology,it is deduced that the future development form is bio friendly mode;2)Guanggang park is rich in historical and cultural resources,animal and plant resources,and has high ecological landscape design potential;3)The high-density residential areas around Guanggang park have formed a special microclimate environment and the visual impact of the surrounding people.According to the wind environment analysis,the comfortable areas of "strong wind in summer and calm wind in winter" and the uncomfortable areas of "strong wind in summer and strong wind in winter" are obtained.According to the thermal environment analysis,the uncomfortable areas of "high temperature in summer and suitable for winter" and the comfortable areas of "low temperature in summer and suitable for winter" are obtained,According to the analysis results of visibility,the building facades that need to be covered are obtained;4)Based on the construction conditions and functional requirements of Guanggang Park in all aspects,it is concluded that the construction objectives of Guanggang park are "important composition of the Pearl River Delta ecological space network","high-quality open space in high-density urban areas" and "natural education demonstration site for ecological construction".It has constructed visual landscape optimization strategies,microclimate regulation strategies and biodiversity design strategies,and designed the overall layout,plant planting,building reconstruction,shading design Guidelines for pavement design and water body design;5)The main target species of Guanggang park are birds,butterflies,fish and amphibians.The park is planned and designed in terms of habitat layout,artificial auxiliary measures,habitat space construction mode and plant species selection. |
