利用生态足迹分析方法,对京津冀区域2012年人口容量进行了分析,结果表明:研究区人均生态足迹是3.266hm2,人均生态承载力为0.444 hm2,理论人口规模为1 318万人,现常住人口已经远远超出了其生态承载力所能够容纳的人口容量,生态形势严峻。按照目前区域生态赤字水平,北京市需要转移人口规模约411万人。京津冀区域生态保护与建设的重点是构建一体化的生态保护与建设格局,划定林地、农田、湿地、海洋和草地生态红线,提高区域生态承载力和人口容量。
The ecological footprint analysis method was used to calculate the population capacity of the Beijing-Tianjin-Hebei region in 2012.The results showed that the ecological footprint was 3.266 hm2 per capita,and its ecological carrying capacity was 0.444hm2 per capita,theoretical population capacity was 13.18 million people,but the present permanent population was far beyond the theoretical population capacity,the ecological situation is extremely serious.According to the regional ecological deficit,Beijing needs to transfer the population size of about 4.11 million people.Focus on ecological protection and construction in this area is to construct the integration pattern,delimit ecological red line for forest land,farmland,wetland,marine and grassland,and improve the regional ecological capacity.
