Exploring the spatio-temporal variations of farmland landscape patterns in a tradi-tional agricultural region can provide scientific support for decision-making on sustainable rural land use and rural vitalization development.This study established a comprehensive evaluation index for farmland fragmentation with multiple aspects(dominance,integrity,ag-gregation,regularity,and connectivity)at the county scale.The goal was to identify the evo-lution of farmland fragmentation in the traditional agricultural region of the Huang-Huai-Hai Plain during 2000-2015 and investigate underlying drivers using panel data of 359 counties.Results showed an accelerating but fluctuating fragmentation pattern of the farmland land-scape.The indexes of dominance,integrity,and aggregation of farmland decreased most sharply,while the index of connectivity increased.Furthermore,the evolution of the farmland fragmentation pattern showed significant spatio-temporal heterogeneity,which is similar to the trajectory of urbanization and land use transition.Farmland fragmentation in municipal districts also emerged earlier and was more severe than in county-level cities and counties.Factors influenced by advancing urbanization include the proportion of artificial land,popula-tion density,and proportion of primary industry;these factors drove the evolution of farmland fragmentation.In contrast,the increase in income of rural residents and production efficiency of farmland were the key factors contributing to the improvement in farmland connectivity.
