Landscape Design Study Of Ecological Park Around The City Of Wenjiachang In Chengdu

In response to the country's policy of accelerating the development of ecological civilization,and preventing urban rapid development from eroding the suburb and destroying its ecological environment,the Chengdu government has planned to develop the ecological protection zone around 500 m on both sides of the circle freeway of Chengdu,and it mainly exists in the form of "Circular City Ecological Park".It stress that reasonably developing and utiling the land of the protected area and vigorously developing the Ecological Park Around City,so as to improve and maintain the urban environment of Chengdu,and give the space of leisure activities on weekends and holidays.First of all,this paper studies the related theories of the ecological park around the city.Secondly,this paper makes a comparative analysis and evaluation on the constructed ecological park in Chengdu by using the analytic hierarchy process and comprehensive evaluation method,and summarizes the successful experience and shortcomings of its construction.It will be used to guide ecological construction project around the city of Qingyang,Chengdu(phase two)-the Wen Jia chang ecological park landscape design,and studys the design principles,objectives and strategies,and analysis the construction method of its spatial layout,ecological water landscape,spongy terrain,plant community and hard landscape.Finally,Combined with theoretical research and empirical application research,and Obtained the Countermeasures for the landscape construction of ecological park around the city of Chengdu.The specific research results are as follows:(1)This paper analyzes the concept of the green belt around the city and the urban ecological park at home and abroad,and determines the scope of the ecological zone around the city of Chengdu,and redefines the definition of the green belt around the city and the urban ecological park.On this basis,this paper discusses the related domestic and international the development and status of ecological park around the city,and reveals that the current ecological park construction mode begins from single to diversified design,and pays attention to the value of ecological restoration,cultural reproduction,natural protection and leisure tourism.It shows that building an ecological park around the city is an effective way to prevent urban marginalization and improve the urban environment.(2)This paper selects the ecological park which has been built in the ecological area of Chengdu as the research case.It structures the comprehensive evaluation index system of Chengdu ecological park by AHP,and determine the weight of various indexes by the method of expert scoring,and then combined with the results of the questionnaire,this paper qualitatively and quantificationally analysises the selected cases.From the three aspects of ecology,landscape and social culture,it objectively evaluates the current situation of the construction of cases,and summarizes the successful experience of the construction of the ecological park in Chengdu to guide the ecological park landscape design around the city of Wen jia chang.(3)Taking ecological park around the city of Wen jia chang as a practical research object,this paper analyzes the current situation of its surrounding environmental resources in the specific landscape design,and puts forward the principles,strategies and methods of the landscape design of the Eco Park by studying the successful experience of the construction of ecological park around the city of Chengdu.The design principles mainly include the ecological priority principle,the functional service principle and the regional culture principle,and the design strategy includes building a good ecosystem,highlighting the regional cultural characteristics and coordinating the overall layout of the region,and while the design methods are mainly embodied in spatial layout,the construction of ecological water landscape,the design of sponge topography,the layout of plant community and the design of hard landscape.It emphasizes that the design should combine the relevant landscape ecology principles and use the advanced ecological technology such as the self purification technology of ecological water body and the cavernous body of the rain and flood to structure a stable biological community and a benign ecological water landscape,and let its site can give full play to its ecological benefits.(4)This paper integrates case studies and the practice and exploration of the ecological park around Wen Jia chang city and puts forward to the countermeasures for the landscape construction of ecological park around the city of Chengdu :building a stable biological community,creating a benign ecological water landscape,building a green environmental protection facility,building a continuous and complete road traffic system,inheriting the spiritual and cultural characteristics of the site,and carrying out the propaganda work.It is expected to provide a reference for the future landscape design of the ecological park around the city.
