摘　　要：耕地资源保护利用对于保障中国粮食安全、生态可持续发展和社会稳定至关重要。本文以吉林省为研究区,以1980、1990、1995、2000、2005、2010、2015年遥感影像及统计数据为数据源,采用转移矩阵模型和耕地压力指数模型,对研究区耕地利用变化的时间特征、空间特征及耕地压力指数进行测算。研究结果表明:在时间尺度上,1980−2015年间耕地数量从701.88×10^(4)ha增加到762.82×10^(4)ha,人均耕地面积从0.1524 ha增加到0.1707 ha,耕地压力指数从0.7922增加到0.7953;在空间尺度上,1980年及1990年吉林省耕地压力主要集中在南部地区,1995年集中在南部和东部地区,2000年集中在西南和东部地区,2005年集中在南部和东南地区,2010年和2015年集中在南部、东南部及中心地区。耕地压力变化的方向主要从吉林省的西北部向东南部转移。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 701.88×10^(4)ha to 762.82×10^(4)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.
