Abstract: By analyzing the development of the regional economy and industry, the distribution of resources and environmental factors, based on the improved Tapio elasticity decoupling theory and evaluation system,and combined with the ecological footprint,carbon emissions,this paper carried out quantitative analysis of the degree of decoupling between economic growth and environmental resources in BTH region from 2000 to 2013. Studies show that:1. Decoupling from the economic growth caused by resource consumption,environmental deterioration of the "growth link" in 2000,gradually transition to the coordination of the "strong decoupling" in 2008. Although the impact of economic development on resources and environment has weakened since 2009,the pressure always exists.(2)There are uneven economic growth and industrial distribution in BTH region,due to the decoupling index of regional differences. Beijing's decoupling is best,Tianjin's resources and environmental pressure is at the regional average level,because of the large proportion of the second industry,resulting in increased environmental pollution,while Hebei province has become a weak link in the regional ecological construction. In the future,the integration strategy of BTH region needs to achieve balanced and sustainable development of economy,resources and environment,to carry out the construction of ecological environment to adapt to the economy and form a new pattern of coordinated development with the same direction,measures,complementary advantages,mutual benefit and win-win situation.
