Natural capital accounting of cultivated land based on three-dimensional ecological footprint model-- A case study of the Beijing-Tianjin-Hebei region

The fairness of the utilization cultivated land resources is essential for balanced development region, but there are few researches to analyze it. Against background urgent need farmland protection and ecological compensation, this paper takes as research object uses a three-dimensional footprint model account natural capital stock flow in Beijing-Tianjin-Hebei region from 2009 2016 terms breadth depth, so provide reference protection, compensation even coordinated regional ecological-economic development. results show that 2016, was generally low depth high, whole tended increase, except Zhangjiakou Chengde, which were able achieve self-sufficiency capital, 85% cities showed phenomenon depletion intensification depletion. After 2010, overall Gini coefficient area less than 0.4, use relatively balanced. study concludes under strategic role integration collaborative development, equity each city has been improved, level creating utilizing flows still needs be further strengthened; excessive caused by agricultural production can used basis cross-regional land, thus supporting value land.
