Abstract:: The changing trend of land resources and food security in the past 25 years was studied by using land relative ratio and sensitivity degree analysis model, based on statistical data of land, population and grain production of Linfen City in Shanxi Province. The results showed that the area of land in this area had an increasing trend while acreage per capita takes on decreasing. The special change of cultivated land resources was significant. The relative bigger change mainly occurred in the east and west of this area where there were hilly region. On the contrary, the alluvial plain regions in the middle of this area showed the smaller relative change. The sensitivity of grain output changes to arable land was enhanced in east and west hilly region than that in alluvial plains. With the increasing of population and the total output of grain, the grain output per capita decreased. Labor resources played an important role in grain production and the area of cultivated land. Food security mainly depends on the protection of basic farmland, improvement of the quality of land, and increasing in the level of agricultural science and technology.
