We calculates the coordination degree between cultivated land quantity, total grain production, per-capita grain production and urbanization level of Wuhu city from 1980 to 2010 based on the coordinated index model between economy and environment. The results indicated that: the coordination degree between cultivated land quantity and urbanization level is lowest, The average coordination degree is0.202, most of the time, the uncoordinated state happened; the coordination degree between total grain production and urbanization level and the coordination degree between per-capita grain production and urbanization level are more idea, the state over harmonic happened most; The average coordination degree is more than 0.45. The research conclusion: most of the time, the quantity of cultivated land is difficult to maintain in the bearing threshold value, and there is a decrease in the overall trend; the change of total grain production and per-capita grain production maintain in the bearing threshold value; the decrease of cultivated land quantity in the urbanization process is greatly weakened the resource base of grain security. Therefore, to maintain the high coordination degree between the urbanization level,food safety and cultivated land protection, we should take into account the cultivated land quantity, cultivated land use pattern and population growth. To assess the pressure on food safety and cultivated land protection reasonably in the process of urbanization.
