Abstract: The fairness degree of distribution and allocative efficiency of natural capital and human-made capital are the guarantee for sustainable sharing of regional ecological resources. Based on calculating ecological footprint in Guanzhong City Group from 2005 to 2014, this paper adopted ecological footprint, ecological carrying capacity and GDP to represent the regional demand of natural capital use, natural capital gains and human-made capital gains. The regional fairness degree of distribution and the allocative efficiency of resources were analyzed by Gini coefficient, spatial-temporal analysis index, ecological support coefficient (ESC) and economy contributive coefficient (ECC). The results showed that the per capita ecological footprint increased from 2.056 hm2 per capita to 3.201 hm2 per capita with an average annual growth rate of 5.04%; the per capita GDP increased from 11 089 yuan per capita to 46 639 yuan per capita with an average annual growth rate of 17.31%; and the per capita ecological carrying capacity changed little in Guanzhong City Group during 2005 to 2014. In the same period, the ecological pressure index (Epi) increased 1.59 times from 4.665 to 7.406 and the ecological footprint for ten thousand yuan GDP decreased from 1.854 hm2 per ten thousand yuan to 0.686 hm2 per ten thousand yuan with an average annual decline rate of 10.45%. The adjusted ecological pressure elasticity coefficient (E′) showed that the changes of ecological footprint was generally inverse to the changes of ecological carrying capacity, and the ecological footprint for ten thousand yuan GDP elasticity coefficient (G) basically ranged between 0 and 1. The ecological support Gini coefficient, economic contribution Gini coefficient and the comprehensive Gini coefficient were between [0.18, 0.20], [0.24, 0.29], [0.23, 0.28] respectively. The conclusion indicated that the ecological pressure became increasingly prominent and economic contribution increased gradually. That means the increase (decrease) in ecological footprint caused by 1% increase (decrease) of GDP is less than 1%, the scale effect of economic is at an optimal level and the ecological elements match well in Guanzhong City Group. Besides, there is no city in Guanzhong City Group that had both relatively high economic contribution and high ecological support contribution. Tongchuan, Baoji, Xianyang had relatively higher ecological support contribution but lower economic contribution while Xi’an, Yangling were opposite.

Key words: ecological carrying capacity, ecological economics, ecological footprint, economic contribution, Gini coefficient, Guanzhong City Group
