The dynamic change of cultivated lands in Meizhou City is analyzed. It is found that the main driving forces of the change are social-economic factors. With the method of principal component analysis, 13 social-economic factors that affect the change of the land are summarized into three groups, which are the growth of population, the development of economy and the yield of agriculture. The total population of the region, the gross value of agricultural output and the agricultural yield are very closely related to the change of cultivated land. Some suggestions are put forward to protect cultivated land in the light of different driving forces: building up scientific thought of development and protection; strengthening the restrictive effect of planning, improving administrative and supervising systems of cultivated land; strengthening basic cultivated land protection and construction; intensifying the rigorous consciousness of protecting cultivated land.
