Based on Landsat and socio-economic data in the Northeast region from 1990 to 2023, this paper analyses the spatio-temporal characteristics of arable land ecological security using ecological footprint and ecological carrying capacity indexes, and explores the influence mechanism using geographic weighting model. The result show that: The per capita arable land ecological footprint increased from 0.135hm² per person to 0.145hm² per person, the per capita arable land ecological capacity decreased from 0.115hm² per person to 0.095hm² per person, and the per capita arable land ecological deficit increased from 0.16hm² per person to 0.058hm² per person. Farmland yield indicators show a decreasing trend, while indicators of ecosystem pressure on arable land show an increasing trend, and overall ecological security tends to improve. The impacts of natural resource on arable land ecological security shows a decreasing trend, while geographical location, socio-economic and regional policies show an increasing trend. This study is of reference value for the rational use of arable land resources and the sustainable development of ecological security.

以1990~2023年东北地区Landsat和社会经济数据为基础，综合运用生态足迹、生态承载力等指数及地理加权模型，分析耕地生态安全时空特征并探讨其影响机制．结果表明：人均耕地生态足迹从0.135hm²/人提升至0.145hm²/人，人均耕地生态承载力从0.115hm²/人降至0.095hm²/人，人均耕地生态赤字从0.16hm²/人增加到0.058hm²/人；农田产量指标呈现出减少态势，耕地生态系统压力指标则呈现增长趋势，整体生态安全性则趋于提升；自然资源条件的影响呈现出递减态势，而地理区位条件、社会经济指标以及区域政策等要素则显示出增强的趋势．本研究对于耕地资源的合理利用及生态安全可持续发展具有参考价值．
