An Optimized Study On The Spatial Layout Of Urban Vegetable Market In Baoding City’s Competitive Show Area Based On The Circle Of Life

As a part of the basic public service facilities and commercial facilities in the city,the urban vegetable market is not only the key guarantee facility of the national "basket of vegetables" project,but also to meet the basic needs of the citizens for fresh food,and also inherits the historical context of the "city".With the emergence of new retail models such as "fresh fruits and vegetables",the development of "traditional vegetable market" has been hindered,and the overall supply capacity of urban vegetable market has been affected,and the construction of urban life circle provides new ideas for optimizing the spatial layout of vegetable market.Based on the study of the theory of life circle and its mode,this paper combines the life circle division mode with the residents’ usual mode of travel,and makes a new exploration of the urban life circle division mode.This paper analyzes the influence factors of the spatial layout of urban vegetable market based on life circle,and constructs the service range of urban vegetable market facilities by model.Relying on the field research,questionnaire and in-depth interview on the use of urban vegetable market by residents of Baoding City’s Jingxiu District,the data collection and analysis of crowd behavior characteristics,demand characteristics and the supply capacity of urban vegetable market were carried out,and the scope of service was constructed based on the current distribution of urban vegetable market,and problems in the spatial layout of urban vegetable market were found.At the same time,according to the history of Baoding City Race Show District and the direction of urban development to choose three types of typical residential areas: urban village residential areas,commercial housing residential areas and enterprise units compound,respectively,to build a life circle model and in-depth research and analysis,to study three types of residential areas urban vegetable market space layout problems.Aiming at the five aspects of planning and management policy,service scope and supply capacity,transportation accessibility and transportation facilities,environmental and health security,human and economic value,based on the three-level urban life circle division mode of"expansion-commuting-community",the three-level urban vegetable market space layout optimization mode of"core-focus-base"is constructed,and the optimization strategy is proposed from three angles:site selection layout,policy guidance and environmental construction.This study studies the optimization of the spatial layout of urban vegetable market from the perspective of life circle,with a view to guiding the balanced and reasonable spatial layout of urban vegetable market,the high-quality development of urban vegetable market,and improving the level of food hygiene and safety of urban residents.
