北京市生态足迹动态变化研究

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。

DYNAMIC CHANGE OF BEIJING'S ECOLOGICAL FOOTPRINT

This paper uses ecological footprint mode which is based on input/output technology to compare Beijing's ecological footprint in 2005 with 2010 with result showing a falling footprint, but not in sustainability. Footprint was classified as inside city, outside city and foreign zones. The inside city zone needs the most ecological footprint. The percentage of governmental consumption ecological footprint in 2010 rises by 9%, the fix capital by 5%, while the rural consumption falls by 14% and inventory by 1%. From the perspective of industry and demand, this paper analyzes the ecological footprint changes of Beijings 39 industries and 3 regions, and calculates that the agriculture, forestry, livestock, fishing, petroleum processing, nuclear processing, transportation, post, and warehousing and other industries occupy a higher percentage of ecological footprint.
