The quantity of cultivated land in Hunan province from 1949 to 2008 is analyzed by Tian.
Yang studied the law of spatial-temporal characteristics on cultivated land resources in Hebei province from 1995 to 2005.Principal component analysis (PCA) and linear regression model have been done to explore the relation between the change of cultivated land and the socioeconomic driving factors [4].
