| With the rapid development of the city,the urban greenway as a multi-functional infrastructure is nore and more favored by urban builders which can protect the stability of urban ecosystems,provide outdoor space,connect the recreational resources,ease the traffic and so on.From the practical experience of foreign greenway into China,to the construction of greenway in Pearl River Delta,Zhejiang and other provinces,and then to the use in Chengdu,Wuhan and others,greenway construction in the domestic urban planning has an important place.Due to the special terrain environmental conditions,increased number of motor vehicles in mountain city,the narrow road is under increasing pressure.Traffic congestion in major citiy is gradually improving,however in mountain city is more serious.In such a developmental background,the construction of greenway in mountain city is particularly important.In mountain city with the changes in terrain,walking is a healthy,basic way of traveling and it accounts more than half of the proportion.Simultaneously,the urban greenway is mainly used for urban residents,so greenway builders need to study and consider how to provide a good use of the environment for the residents.Greenway route selection is the key and decision-making to greenway construction.Route selection not only needs to take the city’s ecological,transportation and other issues into account,but also from the perspective of human requirements.The study of the greenway route selection not only can reflect the city people-oriented development ideas,and can be better accepted and used by residents to guide residents to walk traffic as the preferred way of travel.Emphasis on greenway system planning is focusing on the greenway route selection and need to be targeted.The successful construction of plain urban greenway can only learn from not copy to mountain city.There are more restrictive and specific factors in mountainous city,so in the research process,it muststudy the pedestrian demand for pedestrian environment and the particularity of mountain city.In this paper,based on the review of the development and practice of foreign greenways,the theoretical study of domestic greenway route selection,analysis on the relationship between greenway route selection and walking environment,it aims to establish a greenway route selection model for mountain city.Followed by the walking environment demand theory,this paper studies three aspects including walking and safety,behavior and psychological,aesthetic and emotional demands.And then it researches combine with the urban area of Chongqing as the representative of mountain city of greenway walking environment.In the process,it sums up the common characteristics of the walking environment and the mountain city greenway route selection of the specific demands from the perspective of the demands of the walking environment.And then from the demands of the pedestrian environment and the specificity of the mountain city,it establishes a route selection elementsfor the mountain city greenway walking environment,including 3 first-level indicators,9 second-level indicators and 20 third-level indicators,which contains 14 walking demand elements and6 mountain city special elements.And through the use of analytic hierarchy process,it invites experts and residents to scoring on demand indicators to draw a set of route selection model.Based on the model,it appraises the potential path of the greenway in Jiangbei district of Chongqing in order to using the example to verify the practical significance of the paper.Finally,the shortcomings of this study are put forward,and it hopes to improve and progress in the future. |
