摘　　要：基于投入产出模型分析甘肃省生态足迹有利于把握甘肃省社会经济发展进程中土地资源利用的深层次规律。以2012年中国30省(市、自治区)区域间投入产出表为基础,全面分析了甘肃省与全国各经济区之间不同产业生态足迹互相占用情况以及甘肃省生态足迹。结果表明:甘肃省主要占用沿海地区、西北、中部、地区生态足迹,其中工业间接占用生态足迹是各地区生态足迹经济区域间差异的主要成因;中部地区与沿海地区占用甘肃省生态足迹最高,主要以直接占用甘肃省农业为主;甘肃省人均生态足迹高达30.1 hm 2,是甘肃省土地面积的17.8倍,生态承载能力堪忧;甘肃省8部门中批发零售业与住宿餐饮业人均生态足迹较低,分别为0.17 hm 2与0.07 hm 2,万元GDP生态足迹较低,土地利用效率更高。Based on the input-output model,the analysis of ecological footprint in Gansu Province is beneficial to grasp the underlying law of land resource utilization in the process of socio-economic development in Gansu Province.Based on the inter-regional input-output table of 3 provinces(city,autonomous region)in China in 2012,this paper comprehensively analyzes the mutual occupation of ecological footprints of different industries and the ecological footprints of Gansu Province between Gansu Province and the national economic zones.The results showed that:the ecological footprint of Gansu Province is mainly occupied by coastal areas,northwest,central and regional areas,among which the indirect industrial footprint is the main cause of the difference between the economic areas of the ecological footprint.The ecological footprint of Gansu Province is highest in the central region and the coastal region,mainly directly occupying the agriculture of Gansu Province.The per capita ecological footprint of Gansu Province is as high as 30.1 hm 2,17.8 times of the land area of Gansu Province,and the ecological carrying capacity is worrying.Among the 8 departments of Gansu Province,the per capita ecological footprint of wholesale,retail and accommodation and catering industry is relatively low,which is 0.17 hm 2and 0.07 hm 2 respectively,and the per capita ecological footprint of ten thousand yuan GDP is relatively low,and the land use efficiency is higher.
