Ours is a big agricultural country with such a large population, but limited land resources and the conflict between the two has been growing more and more prominent. How to exploit the land resources in a reasonable, effective and sustainable way is extremely important in tackling with the problem. Since 1949, a great many scholars have been doing profound research on land resources in China, The study on quantitative change in cultivated land is an important aspect of the recent research on land resources. This paper reviews and summarizes main progresses in the study on quantitative change in cultivated land and points out some problems still existing in the study and possible solutions.
