目前，食物浪费及其对环境的影响越来越受到学术界的关注。本研究在对北京市餐饮业进行调查的基础上，分析了北京市餐饮业与食物浪费相关的农业资源的数量、结构、特征和成本。结果表明：(1)北京市居民外出就餐人均餐浪费量约为75.02 g（生），约10.52%的食物被浪费。(2)根据不同类别食物浪费的数量排序，蔬菜浪费最多，其次是肉类、水产品和谷物。其他类别的食物浪费要少得多。(3)食物浪费受餐厅类型、消费者人数、性别、年龄、受教育程度、消费动机的影响。(4)根据人均食物浪费估算，北京市餐饮业每年在消费阶段浪费的食物约为417.92万吨。这相当于浪费了约765.53吨谷物，占北京市谷物产量的79.66%和消费量的13.15%。根据所需的土地使用估算，这一数量的食物浪费意味着北京大约有16612万公顷的耕地被浪费。
Currently,the topic of food waste and its environmental impacts is attracting increasing attention among academic researchers.Based on an investigation of restaurants in Beijing,this study analyzes the quantities,structures,characteristics and costs of the agricultural resources related to food waste in the catering industry in Beijing.The results show that:(1) The average food waste per capita per meal is about 75.02 g (raw) for food away from home among Beijing urban residents,which means that about 10.52% of the food is wasted.(2) According to the quantitative ranking of different categories of food waste,vegetable is the most wasted,followed by meat,aquatic products,and grains.The foods in the other categories are wasted much less.(3) Food waste is affected by the restaurant type,as well as the number,gender,age,education level,and consumption motivation of the consumers.(4) Based on the estimated food waste per capita,about 417.92 thousand tons of food is wasted annually at the consumption stage in the catering industry in Beijing.This food waste amount is equivalent to approximately 765.53 tons of cereals which are wasted,and this represents 79.66% of cereals production and 13.15% of cereals consumption in Beijing.Estimated by the required land use,this amount of food waste means that the total production of approximately 166.12 thousand ha of arable land is being wasted in Beijing.
