Farmland Use Transition in a Typical Farming Area: The Case of Sihong County in the Huang-Huai-Hai Plain of China

An in-depth exploration of the dynamics and existing problems in farmland morphology is crucial to formulate targeted protection policies. In this study, we constructed a morphological evaluation index system identify characteristics use transition Sihong County Huang-Huai-Hai Plain, China. The dominant terms area landscape pattern recessive focusing on function were considered work. Based information, driving factors quantitatively analyzed via mixed regression model. following major findings determined: (1) showed U-shaped change trend during 2009–2018. patch density (PD) an upward trend, mean size (MPS) downward indicating that degree fragmentation increased. implementation land consolidation projects increased aggregation farmland, while urbanization road construction occupied divided leading reduction increase fragmentation. (2) crop production, living security, eco-environmental first decreasing then increasing. Urbanization demand for agricultural products large-scale production had positive impact farmland. Our research highlights increasing should be addressed farming area. Therefore, government efficient policies curb occupation urban traffic utilization.
