摘　　要：随着人们生活水平的提高,饮食问题越来越受到人们重视,现实中由于食物供应点空间分布不均衡、交通不可达性、消费群体本身存在的社会经济因素等原因导致了"食物沙漠",即部分群体无法便利购买到日常所需的食物,一定程度上导致社会不公平性.以福州市为例,结合GIS分析工具,以空间图资、相关统计资料以及网络信息搜集为数据源基础,结合食物供应点、道路网等数据,综合分析福州市食物沙漠分布区,并基于GIS空间分析研究提出哪些食物沙漠区需要设立食物供应点,对政府的城市规划决策具有一定的参考意义.As the improved living standards and the increased requirements for daily life, the diet issue has become more and more important.In reality, the unbalanced spatial distribution of food suppliers, lack of accessibility, different socio-economic condition of consumers, all these factors may result in the "food deserts", which represents some groups can’t easily access to the daily food suppliers and cause the social inequity problem then.This paper aims to combine with GIS software, spatial data, official statistics data, and information from internet to comprehensively analyze the distribution of food deserts, and use Fuzhou city as a case study.Based on the spatial analysis via GIS, the followings are addressed: the suggestions to identify the locations where the more food suppliers are needed or not.This study provides the valuable directions for government to enhance the social equity, reforms the eating habits of citizens, and improves the way of city planning.
