Abstract: In this paper, the authors analyzed the dynamic changes of cultivated land resource in Henan Province during 2002 to 2012 and used the GM(1,1) model to predict the changes of the land pressure indexes in the next 10 years. The results show that in the past few years, the pressure indexes of cultivated land are declining, although a certain amount of cultivated land is occupied with the economic growth of the central China. The main reasons are: the grain productivity is improving and the management efforts of cultivated land are effective with land reclamation techniques. In the next decade, the cultivated land pressure indexes will be reduced and the food supply is greater than demand, which can achieve food security.
