基于广东省土地利用监测与统计数据，采用单一指标测算、ESTDA等方法对广东省县域单元耕地“非粮化”的时空演变与整治路径进行了系统研究。结果表明：(1)2010—2021年广东省耕地“非粮化”率由47.89%升至54.57%，呈显著空间集聚特征，珠三角地区较高而东西两翼较低；(2)珠三角地区LISA时间路径相对长度显著大于其他地区，说明珠三角地区的“非粮化”具有较高的时空稳定性，而弯曲度与其呈相反特征，表现出一定的惰性与活性；(3)广东省耕地“非粮化”整治需按照“组织—结构—模式—机制”的逻辑路线序贯推进。研究结果可为指导广东省耕地保护“双平衡”政策的调整、制定与落实提供科学参考，并对落实国家耕地保护由“小占补”向“大占补”转变具有理论与现实指导意义。

Based on land-use monitoring and statistical data of Guangdong Province, we used the single index measurement, ESTDA and other methods to systematically study the spatio-temporal evolution and management pathway of cultivated land“non-grain”at the county-level units.The results show that(1)the rate of cultivated land“non-grain”in Guangdong Province increased from 47.89% to 54.57% from 2010 to 2021,exhibiting significant spatial clustering characteristics, with higher levels in the Pearl River Delta region and lower levels in the eastern and western wings.(2)The relative length of LISA temporal path in the Pearl River Delta region is significantly greater than that in other areas,indicating that“non-grain”in the Pearl River Delta region shows high spatio-temporal stability, while the curvature has the opposite characteristic,showing certain inertia and activity.(3)The management of cultivated land“non-grain”in Guangdong Province must be carried out sequentially according to the logical route of“organization-structure-mode-mechanism”. This study can provide scientific reference for guiding the adjustment,formulation and implementation of the“dual balance”policy for cultivated land protection in Guangdong Province and has significant theoretical and practical guidance for the transition of national cultivated land protection from“ small compensation ”to“ large compensation”.
