Abstract

The protection of cultivated land resources is critically important for maintaining food production capacity, economic development, and social stability in China. This study analyzed the spatiotemporal characteristics of cultivated land variation in Jilin Province from 1980 to 2015 by taking Jilin Province as the study area, employing the remote sensing images captured in 1980, 1990, 1995, 2000, 2005, 2010, and 2015 and the statistical data from 1980 to 2015 as the basic data, and using a transfer matrix and the cultivated land pressure index model. The results revealed that on the temporal scale from 1980 to 2015, the area of cultivated land increased from 701.88×104 ha to 762.82×104 ha, the area of cultivated land per capita increased from 0.1524 ha to 0.1707 ha, and the cultivated land pressure index rose from 0.7922 to 0.7953. On the spatial scale, the cultivated land pressure in Jilin Province was mainly concentrated in the southern section in both 1980 and 1990, the southern and eastern sections in 1995, the southwestern and eastern sections in 2000, the southern and southeastern sections in 2005, and the southern, southeastern, and central sections in both 2010 and 2015. The change in the direction of the cultivated land pressure force in Jilin Province during the study period was mainly from northwest to southeast.
