Dynamic Analysis of Ecological Deficit in Minqin Oasis

Abstract

Abstract:

Based on the ecological footprint theory,the ecological footprint,ecological carrying capacity,ecological deficit and the ecological footprint of ten thousand yuan GDP of Minqin county in Gansu Province were calculated from 2007 to 2016,and the dynamic changes during 10 years of various indicators were analyzed.The results showed that:1) from 2007 to 2016,the ecological footprint per capita of Minqin was on an increasing trend,which increased by 0.621hm² in 10 years,while slowing down since 2015;2) there was a tendency of slow increase of ecological carrying capacity per capita;3) there was still a serious ecological deficit in Minqin,which increased by 28.35% over the decade.In view of the ecological situation of Minqin,it is suggested to continue to adjust the industrial structure and promote energy conservation and emission reduction to increase the efficiency of bio-productive land use.

Key words: ecological footprint, ecological carrying capacity, ecological deficit, sustainable development, oasis, Minqin
