摘　　要：研究目的:探究东北粮食主产区2010—2020年耕地利用绿色转型的时空格局演变特征和驱动因素,为实现农业高质量发展、耕地保护战略目标提供科学参考。研究方法:熵权法、空间自相关分析和地理探测器。研究结果:(1)2010—2020年研究区耕地利用绿色转型处于中等水平,呈上升趋势,且存在显著的空间异质性,由西北向东南递减;研究期内耕地利用绿色转型指数极差持续扩大;(2)2010—2020年研究区耕地利用绿色转型全局莫兰指数均为正值,空间依赖性及空间溢出效应显著;(3)社会因素、环境因素、农业现代化因素对东北粮食主产区耕地利用绿色转型有显著影响,农业产业发展程度是研究区耕地利用绿色转型的核心驱动因素。研究结论:东北粮食主产区耕地利用绿色转型水平区域差异显著,需制定差异化东北粮食主产区耕地利用绿色转型发展策略。The purpose of this study is to explore the characteristics and drivers of the evolution of the spatial-temporal patterns of green transformation of cultivated land use between 2010 and 2020 in the main grain-producing areas of Northeastern China,to provide scientific references for achieving the strategic goals of high-quality agricultural development and cultivated land conservation.The research methods include entropy power method,spatial autocorrelation model and GeoDetector.The results show that:1)the level of green transformation of cultivated land use in the study area from 2010 to 2020 is at a medium level,and shows an upward trend.There is significant spatial heterogeneity in the green transformation of cultivated land use in the study area,the level of green transformation of cultivated land use decreases from northwest to southeast,and the range of green transformation index of cultivat ed land use between 2010 and 2020 increases.2)The global Moran index of green transformation of cultivated land use from 2010 to 2020 is positive,with significant spatial dependence and spatial spillover effects.3)Social factors environment factors and agricultural modernization factors have significant effects on green transformation of cultivated land use in the main grain-producing areas of northeast China,among which the degree of agricultural industry development is the core driver of green transformation of cultivated land use in the study area.It concludes that there are significant regional differences in the level of green transformation of cultivated land use in the main grain-producing regions of Northeastern China,and it is necessary to promote differentiated development strategies of green transformation of cultivated land use in the main grain-producing areas of Northeastern China.
