Abstract：Thedynamic monitoring of farmland protectionutilizes satelite remote sensing technology to evaluate the spatiotemporal changes of farmland resources，and uses multi-source image analysis to identify degradation，nonagricultural use，and illgalutilization，providingscientific basis forfarmland protectionandresourceoptimization.Based onsatelite remote sensing technology，this paper proposes amulti-source data acquisition methodfor dynamic monitoring offarmland protection，establishesadynamic change monitoringand farmlandqualityinversionmodel，developsadata integrationand earlywarning mechanism，and takes Qingdao cityas theresearch area todeeply analyze the inflow and outflowoffrmland，thedistributionofsuspectedillgalspots，ndtheeffctivenessofrehabilitation，anddemonstratesthe applicationvalueofremotesensing technologyinidentifyingillgallanduse，evaluating farmland protection，anddynamic monitoring systems，thus laying a foundation for land resource management and policy formulation.
