构建基于投入产出技术的生态足迹模型对北京市2005年与2010年的生态足迹进行了对比分析。北京市生态足迹虽有所下降,但仍然处于不可持续状态。在方法上将生态足迹划分为市内、市外和国外生态足迹3个部分,研究得出市内需求占用生态足迹最多,2010年政府消费支出和固定资本形成所占用的生态足迹比重分别上升了9%和5%,农村居民消费和存货调整占用的生态足迹比重下降了1.4%和1%。在结果上,从产业、需求的角度来分析北京市39个产业和3个区域生态足迹变化对北京市生态足迹总量变化的影响,计算分析得出农林牧渔业、石油加工炼焦及核燃料加工业、交通运输仓储业及邮政业和其他服务业占用生态足迹较多。
The ecological footprint model based on input-output technology was constructed to compare and contrast the ecological footprint of Beijing in 2005 and 2010. Although Beijing’s ecological footprint has declined, it is still unsustainable. The method divides the ecological footprint into three parts: the ecological footprint in the city, outside the city and abroad. The study finds that the urban footprint occupies most of the ecological footprint. In 2010, the proportion of the ecological footprint occupied by the government consumption expenditure and the fixed capital formation respectively increases 9% and 5% respectively. The proportion of ecological footprint occupied by rural residents in consumption and inventory adjustment decreased by 1.4% and 1% respectively. In terms of industry and demand, this paper analyzes the impact of changes in the ecological footprint of 39 industries and 3 regions in Beijing on total ecological footprint change in Beijing. The results show that agriculture, forestry, animal husbandry and fishery, petroleum processing coking and nuclear fuel plus Industrial, transportation, warehousing and postal services and other services occupy more ecological footprint.
