Ecological Corridor Planning Under The Background Of "Double Urban Repair" Design Research

Under the background of vigorously promoting the construction of ecological civilization in China,the pilot project of "urban double-cultivation" is in full swing and has become a new way to manage the increasingly serious "urban diseases".However,the application of the concept of "urban double-cultivation" is still in the pilot stage,and there is a lack of relevant practical experience and successful cases.In order to further optimize the ecological function and service function of urban green areas,further promote the development and improvement of urban green areas,and take the "urban double repair"concept as the guiding ideology for the planning and design of urban green areas to meet the increasing material and cultural needs of human beings while improving the quality of urban ecosystem.In this paper,the AVC theory and AHP hierarchical analysis are used to calculate the weight and analysis of the second phase of the Guanggu Ecological Corridor,and to establish a comprehensive evaluation system of urban ecological corridor landscape.The important factors affecting the landscape planning and design of "urban double repair"will be investigated;the strategy and method of "urban double repair" landscape planning and design will be extracted;and finally the landscape planning and design of the second phase of Guanggu Ecological Corridor will be carried out and the corresponding conclusions will be verified.The results of this study are as follows:(1)By reviewing and collecting a large amount of literature,summarizing the relevant theoretical knowledge,taking the concept of "urban double-cultivation" as the guiding idea of urban ecological corridor landscape planning,and based on the relevant theory,the relationship between "urban double-cultivation" and urban ecological corridor planning is demonstrated.The relationship between "urban double-cultivation" and urban ecological corridor planning is demonstrated on the basis of relevant theories;and the current situation and problems of the second phase of the Guanggu Ecological Corridor are studied through field surveys,and the landscape carrying capacity,landscape attractiveness and landscape vitality that affect the landscape planning and design of "urban double-cultivation" are analyzed by combining AVC theory.(2)With the help of AHP hierarchical analysis,we select the factors influencing the three AVC forces of urban ecological corridor landscape planning and design,construct a suitable model of urban ecological corridor landscape comprehensive evaluation system,and calculate the weight value of the three AVC forces and their influencing factors by expert scoring:landscape carrying capacity(0.5438)>landscape attractiveness(0.3460)>landscape vitality(0.1103).0.1103).Among them,the more important influencing factors of landscape carrying capacity are:environmental protection carrying capacity(0.2020),maximum visitor carrying capacity(0.1025),natural landscape carrying capacity(0.1010);the more important influencing factors of landscape attractiveness are:ecological restoration characteristics(0.0719),urban repair characteristics(0.0618),corridor theme image(0.0393);The more important influencing factors for landscape vitality are:policy support(0.0361),corridor management system improvement(0.0229),and tourism industry development(0.0145).This provides a strong data support and theoretical basis for the subsequent research on the landscape planning strategy for the second phase of the Guanggu Ecological Corridor.(3)Combining the results of the evaluation system,the landscape planning and design strategy of the second phase of the Guanggu Ecological Corridor under the concept of"urban double repair" is studied,and the principle of ecological restoration and urban repair,human-land harmony and scientific development is elaborated that the landscape planning under the concept of "urban double repair" should be adhered to.It also guides the design from three aspects of urban ecological corridor space repair,ecological restoration and the integration of intelligent interactive technology,so as to provide planning strategies and methods for the second phase of landscape planning of the Guanggu Ecological Corridor under the concept of "urban double repair",and finally apply the findings to the second phase of the Guanggu Ecological Corridor.Finally,the findings will be applied to the landscape planning and design practice of the second phase of the corridor to achieve the goal of improving urban problems and creating a smart city.This paper combines theory and practice to deeply understand the concept of "urban double repair" and apply it to the landscape planning and design of the second phase of the Guanggu Ecological Corridor,which provides reference and guidance for the landscape planning of similar urban ecological corridors and can promote the development of ecological civilization city construction in China and fundamentally improve the ecological environment to achieve the development goal of beautiful China.The ultimate goal of the development of beautiful China.
