Abstract By the qualitative and quantitative analysis method, we analyze the driving forces of arable land resource change in Jieshou City and find that the arable land resource change in Jieshou City arises mainly from social and economic driving forces. Based on the social and economic indicator data about arable land resource in Jieshou City, we use principal component analysis to establish evaluation index system, and analyze the driving forces of dynamic arable land resource change in Jieshou City during 2006 -2015. It is concluded that Jieshou's arable land change is mainly affected by economic and social factors.
