| With the rapid development of China's society and economy.high-speed urbanization has continuously brought conflicts between natural ecology and culture.As a way to maintain the stability of the urban ecosystem,connect various types of recreational resources in the city,provide open outdoor space,and regulate the city.Multi-functional urban green infrastructures,such as micro-climate,relief of urban traffic pressure,and realization of urban harmony,are increasingly receiving the attention and respect of the general public and urban planners and builders.Since the implementation of the ecological greenway system in the Pearl River Delta in 2012,cities such as Chengdu,Wuhan,and Changsha have begun to construct urban greenways,which has gradually promoted greenways across the country.As a city with a special terrain environment,mountain cities are experiencing increasingly fragile urban eco-environment,insufficient open space,and traffic congestion caused by narrow roads during urban development.Therefore,under this background,The construction of greenways in mountainous cities is particularly important.Jishou City,Hunan Province is a typical mountainous city.In the city's overall plan for 2013-2020,the city proposed the requirements for urban greenways and slow-moving systems.However,due to various reasons,the current green road construction in Jishou City is slow and no system is formed.The green open space in the city is relatively insufficient,and the citizens'recreational needs cannot be met accordingly.On the other hand,the mountainous areas around Jishou City are rich in resources.In order to obtain the needs of leisure and recreation,the people have spontaneously established a number of mountain tours.Under this urban background,this study hopes to explore the green roads that can improve the urban ecological environment,meet the leisure and recreation of the citizens,expand the open space of the city,and organize slow-moving traffic from the perspective of the construction of the green road sy stem in the old urban area of Jishou City.Build method.Based on a review of domestic and foreign greenway theoretical research and development practices,this study clarifies the basic concepts,functions,characteristics,and constituent elements of greenways,and combines the relevant theories of mountainous cities to summarize the characteristics and classification of greenways in mountainous cities.After that,the system theory method is used to analyze the interaction between the elements in the greenway system,and it is concluded that the greenway route is attracted by the city's recreational resources and depends on the characteristics of the urban chain space.At the same time,it combines the actual situation of the old city and comprehensive landscape Relevant theories of ecology,recreation,and transportation,summarize the types of urban recreation resources and related indicators,and construct an evaluation system for each type of resource;then use the analytic hierarchy process to give expert scores to the evaluation indicators and establish the weights between the indicators.Based on this,the appropriateness evaluation of various recreational resources and potential paths in the old urban area of Jishou City was conducted to obtain the attractive value of each resource.Finally,the preliminary route selection of the greenway was obtained by the method of overlay analysis.Relevant urban planning is carried out to adjust the route selection,so as to realize the construction of the greenway network in the old city.At the same time,based on the actual situation and characteristics,the corresponding greenway design concept is proposed.Because Jishou is located in the center of Wuling Mountain,one of the 14 nationally connected poverty-stricken areas,the study of the construction of the green roads in the old city of Jishou will inevitably have positive reference and practice for the construction of green roads in other cities in the area significance. |
