Analysis Of Food Environment Characteristics And Planning Control Strategy In Changsha City From The Perspective Of Health Promotion

In the context of severe public health challenges,building a healthy China and food-safe cities,food issues are becoming one of the hotspots of interdisciplinary research.In recent years,there has been an increasing number of researches in the fields related to food environment and spatial planning in my country,but relatively few researches from the perspective of health promotion.Therefore,this paper takes Changsha City as an example to study the characteristics of Changsha’s food environment from the perspective of health promotion,trying to answer three questions: From the perspective of health promotion,how to analyze the characteristics of Changsha’s food environment? What are the characteristics of the urban food environment in Changsha? Based on health promotion goals,what are the planning strategies for the food environment? Based on the consideration of the above issues,this article will carry out relevant research from three aspects: theoretical combing,empirical exploration and planning strategy research.This article first summarizes and reviews the related research content of health promotion and food environment,food environment and planning and regulation.Based on the comprehensive consideration of macro and micro,subjective and objective considerations,the analysis framework of this thesis is proposed.This article analyzes and studies the characteristics of Changsha’s food environment from the macro and micro levels.The macro level focuses on accessibility,availability and agglomeration levels,while the micro level focuses on the typical old communities in Changsha(Huxiang Community)and the food environment of the newly-built community(Yinguiyuan community),further investigation and analysis of the characteristics and problems of the community’s food environment are carried out from the subjective and objective levels.The objective food environment revolves around food accessibility and spatial density,and the subjective food environment revolves around the residents’ food environment perception,evaluation and needs.On this basis,comprehensive subjective and objective analysis results,summarize the characteristics and problems of typical community food environment.And summarize the similarities and differences of the food environment characteristics of different scales and different types of communities.Finally,through theoretical and empirical research and discussion,combined with the practical experience of international food environmental planning and control cases,the food environmental planning strategy from the perspective of health promotion is discussed.The study found that:(1)From the overall level of the city,the macro-level food supply points of Changsha City present the characteristics of "central agglomerationedge dispersion".The number of unhealthy food stores in the study area accounts for a large proportion,which is four times that of health food stores.At the same time,the degree of agglomeration is more obvious on a smaller scale.(2)From the case studies of typical communities,the food supply points in old communities are rich in variety and densely distributed.It is not convenient for the elderly to buy healthy food,the quality of the food environment and space needs to be improved,there are too many unhealthy food stores around the community and schools,and the residents’ awareness of healthy food needs to be strengthened.The number and density of new community food supply facilities are relatively low,showing a circle The characteristics of increasing style.Issues such as the imperfect food supply system with distinct levels and the poor perception of food accessibility among residents are prominent.(3)Based on the analysis of the health promotion goals and the characteristics of the food environment in Changsha City,combined with the analysis of international experience,further explore the planning of the food environment from the three aspects of optimizing the objective food environment of the city,enhancing the perception of the subjective food environment,and integrating food issues into the land and space planning.Strategy.
