| As an important public place for residents to shop,consume and communicate with neighbors,the vegetable market is closely related to residents’ daily life and is one of the essential livelihood facilities in urban communities.The state has successively issued a series of policy guidelines such as "Opinions on Invigorating Circulation and Expansion of Consumption","Notice on Assessment Measures for the " Vegetable Basket " Mayor’s Responsibility System",to ensure that the "Vegetable Basket" project is a key project for the national people’s livelihood,and it is the key to the supply of agricultural and sideline products for urban and rural residents.important support.Secondly.In 2018,the Ministry of Housing and Urban-Rural Development issued a new version of the "Urban Residential Area Planning and Design Standard GB50180-2018",which uses the appropriate walking time as the basic basis for the division of residential areas and the allocation of facilities.Large supermarkets,comprehensive markets,and fruit and vegetable convenience stores are important components of urban vegetable markets.The rationality of their planning and layout affects the convenience of residents’ daily life and the possibility of walking.Based on the research perspective of walking orientation,this paper aims to realize the walking characteristics and needs of residents In order to effectively match the layout of various vegetable market facilities,an empirical study was carried out by taking the builtup area of Yanta District of Xi’an as an example,mainly from the following aspects.First,analyze the current situation,characteristics and problems of vegetable market space distribution in the built-up area of Yanta District of Xi’an.First,clarify the development situation of Yanta District from the perspective of social economy and residential space distribution,and clarify the basic composition and related configuration requirements of the vegetable market.Large supermarkets,comprehensive markets,and fruit and vegetable convenience stores are the research objects of this paper;secondly,the spatial distribution characteristics of vegetable markets in Yanta District are clarified by combining analysis methods such as kernel density and service coverage,and it is found that there are differences in scale configuration of existing vegetable market facilities,walking distance The main problems are low level of development,uneven spatial distribution,and limited spatial resources in built-up areas.Second,analysis of the characteristics and needs of residents walking in the vegetable market in the built-up area of Yanta District of Xi’an.Based on the empirical investigation on the characteristics and needs of residents in the built-up area of Yanta District of Xi’an,three main groups of people are divided into three groups based on the age structure,from walking frequency,actual walking time,walking tolerance time,distance attenuation law,walking satisfaction Summarize from multiple perspectives such as walking speed,and clarify the control variables for the optimization of vegetable market layout based on residents’ walking characteristics and needs,including individual scale indicators,service radius,and construction area per thousand indicators,etc.The layout optimization of provides a research basis.Thirdly,research on the optimization strategy of vegetable market layout in the builtup area of Yanta District of Xi’an.Based on the characteristics of residents’ walking behavior,walkability is taken as the primary basis for facility configuration.Determine the optimization strategies such as high-relationship facility circle,hierarchical division,and functional compounding of the vegetable market,and take the built-up area of Yanta District of Xi’an City as an example research object,set up the location allocation model of vegetable market facilities according to different optimization principles,and form a large supermarket,comprehensive Preliminary layout optimization plan for markets,fruit and vegetable convenience stores;secondly,on the basis of the layout plan,combined with individual facility scale indicators,per capita indicators,and other planning layout indicators and population distribution overview,determine the facility scale control proposals,and on the basis of the planning layout plan First,re-evaluate the coverage of walking services to ensure the full coverage of the facilities within walking distance after optimization;finally,in view of the limited available stock space in the built-up area of Yanta District of Xi’an,scattered and uneven distribution of land,according to the situation of large supermarkets and comprehensive Based on the service overlap of markets and fruit and vegetable convenience stores,an information table for the selection of alternative facilities for vegetable market facilities is proposed to effectively match the layout of vegetable markets with the needs of residents,and provide guidance for the optimization of the layout of vegetable market facilities in the built-up area of Yanta District of Xi’an. |
