论文选取我国1987—2013年土地利用、温室气体排放和用水量数据,运用投入产出法计算足迹家族中的土地足迹、碳足迹和水足迹,采用纵横向拉开档次法进行足迹整合,将整合得到的足迹综合指数与足迹家族各项指标取对数后进行环境库兹涅茨曲线分析。计算结果表明:足迹综合指数从1987年的2.274 2增长到2013年的3.816 9,与人均GDP呈平缓型曲线协同增长关系,说明生态占用持续增加,呈现资源利用的不可持续性;土地足迹、碳足迹与水足迹的环境库兹涅茨曲线分别呈∽型、协同增长型以及平稳型,说明我国城镇化正在进入转型期,碳排放仍处于上升阶段,水资源可持续性不乐观,指标的选取影响环境库兹涅茨曲线形态。
This paper chooses the data of land use, greenhouse gas emission and water use in our country from 1987 to 2013, calculates the land footprint, carbon footprint and water footprint in the footprint family by using the input-output method, adopts the vertical and horizontal pull-out grade method to integrate the footprint, The resulting footprint composite index and the footprint family of indicators take log Kuznets curve analysis. The calculation results show that the comprehensive index of footprints increased from 2.274 2 in 1987 to 3.816 9 in 2013, showing a moderate curve synergistic increase with GDP per capita, indicating that ecological occupancy continues to increase, showing the unsustainability of resource utilization. Land footprint, carbon The environmental Kuznets curves of footprint and water footprint show the pattern of ∽ type, synergistic growth type and steady type, respectively. This indicates that China’s urbanization is entering a transitional period, its carbon emissions are still on the rise, the sustainability of water resources is not optimistic, and the selection of indicators Environmental Kuznets Curve Morphology.
