Taking the cultivated land in Hanjiang District,Yangzhou City as the research object,based on the analysis of the current situation of cultivated land quantity and quality,the land use dynamic change analysis method was used to analyze the spatial-temporal changes of culti-vated land quantity and quality,and the grey correlation method was used to analyze the driving factors of cultivated land quantity changes.The results showed that during the research period,the area of cultivated land had been reduced,and dynamic degree was small.Affected by the rapid development of urban and the adjustment of agricultural structure,the reduced cultivated land was mainly converted into construction land and forest.New cultivation land mainly came from projects such as increasing or decreased urban and rural land,replenishment of cultivat-ed land,comprehensive land remediation,etc,quality of cultivated land was higher.Urbanization rate,total population,second and tertiary in-dustries occupy regional GDP,GDP,total grain output and sowing area of grain crops were the main driving factors affecting changes in the number of arable land.
