食物沙漠是指在其他发达国家的城市环境中，健康食品供应不足的地方。其中包括蔬菜、水果和谷物，这些都是健康饮食所需的物品。缺乏健康食品给居民带来高昂的费用，并与不良饮食造成的健康问题有关。我们试图通过使用地理信息系统和遥感技术来定量地定义这种沙漠，并衡量距离对消费者造成的成本，来研究和改进食物沙漠的讨论。我们最初的应用这些方法是在劳伦斯，堪萨斯，美国的小城市，虽然所提出的方法是适当的农村和城市社区以及。(C)2010爱思唯尔有限公司保留所有权利。
Food deserts are places in the urban environment of otherwise developed nations that are poorly served by access to healthful food. Included in these are vegetables, fruits, and cereals comprising the items needed for a healthy diet. The lack of healthful food imposes high costs on residents and is associated with health problems resulting from poor diets. We attempt to examine and refine the discussion of food deserts by using geographic information systems and remote sensing to quantitatively define such deserts and to measure the costs of distance imposed on consumers. Our initial application of these methods is in the small city of Lawrence, Kansas, USA, though the methods presented are appropriate for rural and urban communities as well. (C) 2010 Elsevier Ltd.
