摘  要:
Starting from the new perspective of the dynamic equilibrium of total cultivated land and based on an analysis of the general trend of change in and composition of the arable land resources of the municipality,this article studies the dynamic change of cultivated land and food production of Chongqing from 1997 to 2006,using the statistical data of that period,and analyzes the dynamic equilibrium of total cultivated land according to the subsystems of arable land,population and food.In view of the continuing decline of arable land and steady growth of population,this article offers some countermeasures to tackle these problems.
