基于生态足迹理论,计算2007—2016年间甘肃省民勤县生态足迹、生态承载力、生态赤字和万元GDP生态足迹,分析10年间各指标的动态变化。结果表明:1)2007—2016年间民勤县的人均生态足迹呈增大趋势,10年共增大了0.621hm²,2015年以来有所减缓;2)人均生态承载力存在缓慢增大的趋势;3)民勤县依然存在较严重的生态赤字,10年间增加了28.35%。针对民勤生态现状,建议继续调整产业结构并推动节能减排进程,以增加生物生产性土地利用效率。

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.
