食物浪费研究已经成为国际研究热点,食物浪费带来的资源环境效应也成为全球关注的焦点。本研究基于实证分析,在大规模实地调查基础上,对餐饮业食物浪费的数量、结构、特点及农业资源代价进行了研究。研究结果表明:1)北京市城镇居民在外就餐消费平均每餐人均浪费生食量为75.02 g,浪费率约为10.52%。2)在各类食物中,蔬菜的浪费量是最高的,其次为肉类、水产品和谷物,其他类食物浪费量较少。3)食物浪费受餐馆类型、消费者人数与性别、年龄、受教育程度和就餐目的等因素影响并表现出不同的特点。4)北京城市餐饮业食物浪费总量约为41.79万吨/年,这意味着北京市每年仅餐饮业餐桌消费浪费约76.55万吨粮食,是北京市粮食总产量的79.66%,粮食总消耗量的13.15%,相当于北京16.61万公顷耕地的无效生产,占北京市耕地总面积的75.12%。
