Abstract: 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.

Key words: Beijing-Tianjin-Hebei region, ecological footprint, population capacity
