By analyzing the cultivated land data from different sources in different phases after 1949,the paper considers the statistics with more errors happens during 1960-1985.According to the systematic data on land use gathered in the 1996 survey,based on reverse deduction of the cultivated land area from 1986 to 1996,and deduction of the cultivated land area from 1960 to 1985 by stages by employing yield of grain,this paper redescribed the actual changing trend and character of Chinese cultivated land and analyzed the driving force of the policy relative to cultivated land to cultivated land area change.

针对该问题，论文对1949～2003年不同时期不同来源的耕地数据系列进行分析，认为统计数据存在问题较多的时期为1960～1985年，并采用粮食产量对耕地面积进行了分时期的反演，对于1986～1996年间的耕地数量则按照全国土地利用详查统一到1996年的结果再进行反推，由此重新刻画建国以来中国耕地资源数量变化的趋势和特征，并结合不同时段耕地相关政策对耕地数量变化的驱动作用进行分析。

结果表明，1949年以来中国耕地资源数量呈现波动性变化，但在1979年之前总体上是增加的，自20世纪80年代起呈现缓慢下滑，1999年后由于生态退耕等原因引起耕地数量迅速减少，由此导致的中国粮食安全问题与耕地安全问题值得关注。
