Abstract：On the basis of man -grain relationship,using the land carrying capacity (LCC)and land carrying capacity index (LCCI)models,from 3 spatial scales,province,region and county,the spatial -tem-poral variation of land carrying capacity was quantitatively evaluated in Shanxi from 2003 to 2012.The results showed that:(1)The provincial land carrying capacity showed an increasing trend from 2003 to 2012.Since 2009,the LCCI decreased.However,the increasing population resulted in lacking of grain.(2)The land car-rying capacity was in the order of Jinnan >Jinbei >Jinzhong.Jinnan kept balance between population and grain,and had great development potential.But Jinzhong had been seriously overloaded.The LCC improved in these regions in 10 years,and the increase range was Jinnan >Jinzhong >Jinbei.(3)The overloading coun-ties mainly located in Jinzhong.The food surplus counties mainly distributed in the north and southeast of Shanxi.The number of man -grain balancing county increased by 18 from 2003 ~2007 to 2008 ~2012, which indicated that the man -grain relationship was improved.
