The Construction Of Slow Corridor Under Urban Interaction

Nowadays,“slow” life has gradually led people to change their own lifestyles and lead people to pursue leisure and lifestyle requirements such as “slow life” and “green transportation”.The city is like a huge complex system,and the slow network is an integral part of the city.Due to its suitable reach,wide range of radiation and beautiful ecological environment,the urban slow-moving corridor has become the choice of more and more urban residents to enjoy the “slow life”.In recent years,many central cities across the country have practiced slow-moving corridors.The primary goal of practice is to integrate urban slow-moving road traffic.However,in the face of urban space covered by slow-moving traffic,the space of slow-moving corridors is the same.It is a problem that needs to be solved in the field that makes the public's sense of identity lack and the participation of social activities decline sharply.This paper takes the Jinjiang Greenway in Chengdu as the research object,analyzes the ecological environment,space and function of the slow corridor from the perspective of urban interaction,and fully considers its environmental characteristics as a slow corridor.Through the literature review,frequency statistics,expert consultation and grey statistical method,the environmental suitability evaluation index system of Chengdu slow-moving corridor was selected,and clustering analysis method was applied to the urban environment of Chengdu Jinjiang slow-moving corridor under urban interaction.After the division,the AHP method is used to calculate the weights of each evaluation index,and finally the Jinjiang slow-going corridor system framework is constructed.Based on this,the optimization strategy of Jinjiang slow-moving corridor construction in Chengdu is proposed,in order to provide new construction ideas for the construction of Tianfu Greenway.Through the research,the following main conclusions are drawn:1 This paper applies a variety of mathematical statistics methods to screen and determine the indicators,and builds a Jinjiang slow-moving corridor composed of four criteria layers and 22 indicators.Environmental suitability evaluation indicator system.2 The three representative types of Jinjiang slow-moving corridors in Chengdu will be divided into three types: the first type of urban backbone slow-moving corridors,the second-class urban trunk slow-moving corridors and the third-class urban characteristics.The slow-moving corridor basically covers the environmental characteristics of the overall slow-moving corridor in Jinjiang,Chengdu.3 There are differences in the weights of the slow-track corridor indicators of the three different environmental types.In the criterion layer,the ecological environment degree and function development index of urban branches and slow corridors have the highest weight;the urban characteristic slow corridors have the highest weight requirements for space display and characteristic degree;the urban backbone slow corridors are in the social function index.Higher than the other two types of slow corridors.The results of horizontal comparison of the weights of each criterion layer and the indicator layer basically reflect the results of the adaptive evaluation of various types of slow-moving corridors,and also reflect that future construction optimization should also be based on different environmental characteristics.4 Through the construction of the urban Jinjiang slow-track corridor environmental suitability evaluation system under the interaction of the city,the interaction between the four cities including the ecological environment degree,spatial display and characteristic degree,social function index and functional development index was determined.Corridor influence factors,and divided the types of Jinjiang slow-moving corridors,including urban backbones,urban branches and urban features,and finally determined the structure of the Jinjiang slow-moving corridor system.5 Through the determined system structure,three problems of the Jinjiang slow-moving corridor in Chengdu are identified: the ecological environment is obviously broken,the corridor space display is unclear,and the social function quality is not good.6 propose a differentiated management strategy based on the architecture and weighting indicators.The urban backbone type mainly follows the principle of equal emphasis on permeability and cohesiveness,guides the economic development index,and further improves the ecological environment system on the basis of functional service guarantee.Because of its high ecological service pressure,the urban branch type is recommended for its protection.The urban characteristic model bears the display of regional characteristics and characteristic space display,and provides multi-angle visual function with relatively rich topography and landform.It is recommended to use the characteristic resources to combine the urban development trend to guide the corridor to strengthen and upgrade.
