根据相关统计数据,应用生态足迹理论和方法,对北京2000--2012年生态足迹和生态承载力进行测算和分析,结果表明:在13年间,人均生态足迹为3.08~3.61Ghm2,呈抛物线波状发展态势;人均生态承载力呈逐年下降趋势,从2000年0.22Ghm。降至2012年0.14Ghm2;人均生态足迹比生态承载力高13,3~20.8倍,亦呈增长态势,导致人均生态赤字维持在2.89~3.44Ghm。的高水平上,北京地区始终处于巨额生态赤字之中。生态赤字组成由大到小依次是能源、耕地、草地、林地和水域,只有建筑用地为生态盈余;区域人口增长过快和资源消耗量过大是导致北京巨额生态赤字的重要原因;促进社会经济平衡发展、强化科技创新与成果推广和资源节约成为缓解生态赤字的关键对策。
根據相關統計數據,應用生態足跡理論和方法,對北京2000--2012年生態足跡和生態承載力進行測算和分析,結果錶明:在13年間,人均生態足跡為3.08~3.61Ghm2,呈拋物線波狀髮展態勢;人均生態承載力呈逐年下降趨勢,從2000年0.22Ghm。降至2012年0.14Ghm2;人均生態足跡比生態承載力高13,3~20.8倍,亦呈增長態勢,導緻人均生態赤字維持在2.89~3.44Ghm。的高水平上,北京地區始終處于巨額生態赤字之中。生態赤字組成由大到小依次是能源、耕地、草地、林地和水域,隻有建築用地為生態盈餘;區域人口增長過快和資源消耗量過大是導緻北京巨額生態赤字的重要原因;促進社會經濟平衡髮展、彊化科技創新與成果推廣和資源節約成為緩解生態赤字的關鍵對策。

Based on the theory and methods of ecological footprint, ecological footprint and ecological capacity in Beijing from 2000 to 2012 were calculated and analyzed according to the relevant statistics. The results showed that, during the 13 years, the ecological footprint per capita was between 3.08 Ghm2 and 3.61 Ghm2, it had a parabolic wave change trend; The ecological capacity per capita declined year by year, it decreased from 0.22 Ghm2 in 2000 to 0.14 Ghm2 in 2012; Meanwhile, the ecological footprint per capita were 13.3-20.8 times more than the ecological capacity per capita with an increase trend, which led to the ecological deficit per capita at a high level between 2.89 and 3.44 Ghm2. Obviously, Beijing area had always been a huge ecological deficit in the new century. There were ecological deficits in different lands with a descending order, which were carbon land, cropland, grazing land, forest land and fishing ground, but only an ecological surplus in built up land; The important reasons caused the mas- sive ecological deficits were the excessive growth of regional population and excessive resource consumption in capital area; And the key countermeasures relieved Beijing's ecological deficit were the balanced development of social economy, technological innovation and achievement popularization, and resource conservation.
