摘　　要：基于生态足迹模型,将中原城市群及其所涵盖的30个地级市作为研究对象,对2005-2018年生态足迹、生态承载力等相关指标进行了测算与时空变化分析,旨在从生态供需的角度对研究区的可持续发展状态做出定量评价。得出以下结论:2005-2018年,中原城市群的人均生态足迹先上升后下降,整体呈倒“U”型的变化趋势;人均生态承载力不断下降;在研究时间段内,中原城市群始终处于“求远大于供”,生态赤字的状态,且赤字先扩大后缩小。空间上,中原城市群人均生态足迹的空间差异显著,总体呈“西北高,东南低”的分布格局;人均生态承载力的空间差异较小,且呈“四周高,中间低”的空间分布格局;人均生态赤字的空间分布格局和人均生态足迹的空间分布格局相一致。Based on the ecological footprint model,the ecological footprint and ecological carrying capacity of 30 prefecture-level cities in the central plains urban agglomeration were measured and analyzed from 2005 to 2018,aiming to quantitatively evaluate the sustainable development status of the study area from the perspective of ecological supply and demand.The conclusions are as follows:from 2005 to 2018,the per capita ecological footprint of central plains urban agglomerations increased first and then decreased,presenting an inverted u-shaped trend as a whole.Percapita ecological carrying capacity continues to decline;During the research period,the central plains urban agglomeration is always in the state of“demand far exceeds supply”and ecological deficit,and the deficit first expands and then shrinks.In terms of spatial distribution,the per capita ecological footprint of central plains urban agglomerations was significantly different,with a distribution pattern of“high in the northwest and low in the southeast”.The spatial difference of per capita ecological carrying capacity was small,and the spatial distribution pattern was“high around,low in the middle”.The spatial distribution pattern of per capita ecological deficit was consistent with that of per capita ecological footprint.
