摘　　要：测算了2003—2019年黄河流域地级市的生态足迹及赤字水平,从多个维度分析时空分异特征并考察环境库兹涅茨曲线的空间效应。结果表明:(1)总体而言,黄河流域生态足迹高于生态承载力,大部分地区处于赤字状态。赤字主要来源于化石燃料用地以及耕地,林地和建筑用地已从赤字转为盈余状态,流域生态治理初见成效。(2)分区域看,生态足迹与赤字在西北和东部存在两个高集聚区;分流域来看,上游生态足迹及赤字增长趋势明显,中游保持稳定,下游处于下降通道,上游和中下游生态赤字分别由能源账户和生物账户推动。(3)整体上经济发展会提升黄河流域生态足迹,处于环境库兹涅茨曲线左端;分流域来看,下游已经越过环境库兹涅茨曲线拐点,上游没有明显的空间效应,中游和下游分别表现为“虹吸”和“扩散”效应。This paper measures the ecological footprint and deficit levels of prefecture-level cities in the Yellow River Basin from 2003 to 2019,and analyzes the spatio-temporal differentiation characteristics from multiple dimensions and investigating the spatial effects of the environmental Kuznets curve.The findings are as follows:(1)Generally,the ecological footprint in the Yellow River Basin exceeds the ecological carrying capacity,placing most areas in a deficit state.Fossil fuel land and cultivated land which has mainly contribute to this deficit,and forest land and building land have shifted from deficit to surplus,indicating that the basin's ecological governance has yielded initial results.(2)Regionally,two high concentrations of ecological footprint and deficit appear in the northwest and the east.The upstream ecological footprint and deficit have significantly increased at the river basin level,the middle reaches have remained stable,and the downstream shows a declining trend.Energy accounts and biological accounts drive the ecological deficits in the upstream and middle downstream,respectively.(3)Overall economic development increases the ecological footprint of the Yellow River Basin,positioning it at the left end of the environmental Kuznets curve.Concerning the watershed,the downstream area has moved past the inflection point of the environmental Kuznets curve,with no apparent spatial effect in the upstream area.In contrast,the middle and downstream areas exhibit"siphon"and"diffusion"effects,respectively.
