北京市居民“菜篮子”产品可获性分析

Analysis of Beijing Residents'Access to Non-staple Food Products

随着食品安全与保障体系的不断发展,微观层面的食物保障成为食物保障的新要求。零售环节是城市食物供给的终端,“菜篮子”产品零售终端的空间格局直接影响着家庭、个人对食物的可获性。以GIS空间分析技术为支撑,对北京市四环内“菜篮子”产品零售终端、道路网络与居民点进行空间统计和分析,基于居民点至最临近零售终端的道路距离探析居民的“菜篮子”产品可获性。最后,根据研究结果提出改善“菜篮子”产品可获性、改进微观层面城市居民食物保障的对策建议。

With the continuous development of food safety and security system,micro level food security has become a new requirement of food security.Retail outlet is the terminal of urban food supply.The spatial pattern of retail oulets directly affects the food acquisition of families and individuals.Supported by GIS spatial analysis technology,the spatial pattern of non-staple food products retail outlets,road network and residential area in Beijing Fourth Ring Road were analyzed.Based on the purchase distance between residential area and the nearest retail outlet,residents'access to non-staple food products was analyzed.Finally,based on the research results,countermeasures and suggestions on improving the spatial access to non-staple food products and enhancing the food security of urban residents at the micro level were put forward.
