| 摘 要： | 以河北省康保县为研究对象在对1993、2001、2008年3期遥感影像解译分析的基础上,得到了3个时期的9种土地利用类型的面积、转移矩阵及时空格局变化情况。结果表明,16年来康保县旱耕地为最大的转出源,草地、林地为最大的转入源,水浇地面积增幅大;2001年以前退耕还林还草集中在北部低山和东部缓坡丘陵区,2001年以后集中在南部波状平原和东部缓坡丘陵区。虽然该县退耕还林还草效果较显著,但距离形成以牧为主、牧农林相结合的土地利用结构,恢复以草原生态系统为主的植被覆被景观仍有大量工作要做。

| Abstract: | With a case study of Kangbao County in Hebei Province,on the basis of the analysis of three remote sensing image interpretation,the area,transfer matrix and temporal pattern changes of nine kinds of land use types were obtained.The results showed that the area of farmland was the largest to be transferred,while that of grassland and woodland was the largest to be transferred into,the irrigated area increased significantly,the return of farmland to woodland and grassland mainly concentrated in north and east hilly regions before 2001,while in south wave plains and east hilly regions thereafter.Although the policy of returning farmland to grassland and woodland has achieved remarkable effects,there are still a lot of work to do to form the animal husbandry-based land use structure combining forestry and agriculture together,and restore the grassland landscape. |
