摘　　要：基于Landsat MSS和TM影像数据,应用RS、GIS软件和景观生态学方法,以拜泉县为例分析了1979～1990年、1990～2001年两个时段土地利用及景观格局的动态变化情况。结果表明,拜泉县以农田和建设用地为主,林地大幅度增加,各土地利用类型相互转移,从1979年到2001年,农田面积减少了15.53%,林地、水体、草地、建设用地面积分别增加了710.71%、66.44%、13.73%和133.69%,土地利用率逐渐提高。运用分维数、优势度指数、破碎度指数、多样性指数等景观指数分析了拜泉县景观格局变化过程,斑块数总体呈增加趋势,表明景观整体上破碎化程度增加,这是因为人类对生态环境的干扰越来越大。Based on Landsat MSS and TM images, dynamic changes of the land use and the landscape between 1979-1990 and 1990-2001 were analyzed by applying RS and GIS softwares and the method of land- scape pattern. The results indicated that the land use types transfered from one to another, between 1979-2001, the farm land area reduced 15.53%, the areas of wood land, water body, grass and construction land were relatively increased 710.71%, 66.44%, 13.73%, 133.69%, land use ratio gradually increased. The process of the landscape change of Baiquan county were analyzed by applying fractal dimension, dominance index, fragmenta- tion index and diversity index. The patch number trend was increasing, which indicated that the fragmentation degree of landscape was increased due to the disturb from human action to the eco-environment.
