摘　　要：为促进河南省农业经济与生态协调发展,首先考虑农业生产对水资源及气候的影响,分别测算河南省2000—2020年灰水足迹与碳排放;其次从农业生产对经济与环境的影响角度,对比农业产值增长率与灰水足迹和碳排放的平均增长率,综合评价河南省农业生态经济发展状态;最后从投入产出角度,运用超效率SBM模型,将灰水足迹与碳排放作为环境指标纳入生态效率评价体系,测算2000—2020年河南省农业生态效率,并作出评价。结果表明,灰水足迹主要呈现三阶段“上升-下降”的倒“√”形特征,碳排放呈现两阶段“上升-下降”的倒“√”形特征;除个别年份外,农业经济影响均大于环境影响,且近年来环境污染明显改善;2000—2004年,河南省GWCAEE处于有效状态,2005-2014年,河南省GWCAEE呈波动下降趋势,持续处于无效状态,2015-2020年,河南省GWCAEE逐步提高,并在2019年达到有效值。In order to promote the coordinated development of the agricultural economy and ecology in Henan Province,firstly,con⁃sidering the impact of agricultural production on water resources and climate,the grey water footprint and carbon emission of Henan Province from 2000 to 2020 were calculated respectively.Secondly,from the perspective of the impact of agricultural production on the economy and environment,the growth rate of agricultural output value was compared with the average growth rate of the grey water footprint and carbon emission,and the agricultural ecological development status of Henan Province was comprehensively evaluated.Finally,from the perspective of input and output,using super SBM model,the grey water footprint and carbon emission were taken as environmental indicators into the ecological efficiency evaluation system,and the agricultural ecological efficiency of Henan Province from 2000 to 2020 was measured and evaluated.The results showed that the grey water footprint was mainly inverted“√”in three stag⁃es,and the carbon emission was inverted“√”in two stages.Except for a few years,the economic impact of agriculture was greater than the environmental impact,and the environmental pollution had improved obviously in recent years.From 2000 to 2004,the GW⁃CAEE in Henan Province was in an effective state,from 2005 to 2014,the GWCAEE in Henan Province showed a fluctuating down⁃ward trend and remained in an inefficient state,and from 2015 to 2020,the GWCAEE in Henan Province gradually increased and reached an effective value in 2019.
