【摘要】：以北京市消耗食物生态足迹的距离为研究核心。结果表明2008年至2012年,北京的生态足迹距离、人均生态足迹和生态足迹总里程总体呈现逐年增长趋势:生态足迹距离增大到676.75 km,增长19.3%;人均生态足迹距离增加到18.42万km,增长54%;生态足迹总里程增加了1倍强,达到56亿t km。北京市的食物生态足迹距离不断扩大,并涵盖了全国大部分地区,北京城市化的生态成本上升。所消耗各类食物的生态足迹距离从大到小分别为水果类、蔬菜或粮油类、肉蛋类和水产类。蔬菜类和水果类的生态足迹距离存在明显的季节波动,且冬春季节远高于夏秋季节。从转移生态承载力来源地的视角,直线距离越远、占据市场份额越大的地区,对北京市消耗食物生态足迹距离的贡献率越高。
[Abstract]:The study focuses on the distance of food ecological footprint consumed in Beijing. The results show that from 2008 to 2012, Beijing's ecological footprint distance, The per capita ecological footprint and the total mileage of ecological footprint are increasing year by year: the distance of ecological footprint increases to 676.75 km, the increase is 19.3km, the distance of per capita ecological footprint increases to 184200 km, the total mileage of ecological footprint increases by 54%, and the total mileage of ecological footprint increases more than twice, reaching 5.6 billion t / km. The food ecological footprint of Beijing is expanding and covers most of the country, and the ecological cost of urbanization in Beijing is rising. The ecological footprint of food consumption ranged from large to small: fruit, vegetables or grain and oil, meat and eggs and aquatic products. The ecological footprint distance of vegetables and fruits has obvious seasonal fluctuation and the winter and spring seasons are much higher than the summer and autumn seasons. From the point of view of transferring the origin of ecological carrying capacity, the farther the straight line distance is, the greater the market share is, the higher the contribution rate is to the distance of food consumption ecological footprint in Beijing.
