Abstract:

Based on the ecological footprint model,this paper analyzed the per capita ecological footprint and ecological carrying capacity in JingJinJi and JiangZheHu region,and compared the nuclear cities of the two regions.The results indicate that both regions have an increasing trend of ecological deficit.It is also found that the per capita ecological deficit of JingJinJi is higher than that in JiangZheHu in most years,and the ecological footprint indices in Beijing,Tianjin,Shanghai,and the nuclear cities of the two regions,are all on the rise.The per capita ecological footprint and the per capita ecological deficit of Tianjin and Shanghai are higher than those in Beijing,respectively.The per capita ecological footprint of Shanghai is 14% higher and the per capita ecological deficit 279% higher than that of Tianjin. In future,both regions should improve the efficiency of resources use through technological innovation.The changing of the mode of production and life style will also be useful to the sustainable development of the regional economy
