摘要： 根据内蒙古多伦县2000年TM影像和2008年SPOT5影像及地面调查资料,在ArcGIS和ERDAS等软件支持下,获得多伦县2期景观类型数据,并运用景观生态学原理与方法,分析了多伦县2000-2008年景观格局动态变化,以期为多伦县土地资源的合理规划与利用提供决策依据,也为荒漠化治理提供理论依据。结果表明:林地面积增长最快,增长了12.09倍,年变化率为1.51%,优势度指数增加明显,破碎度指数和分维数减小;沙地面积减小最为明显,减小了16107 hm2,占2000年沙地总面积的85.1%,年变化率为0.11%,随着斑块数量的增加破碎度指数呈增加趋势,沙地景观类型重心向西北方向转移21.13 km。草地斑块数呈减少趋势,但是斑块面积增加了36150 hm2,占2000年草地总面积的16.4%。综上所述,表明多伦县生态环境趋于良性发展。

Abstract: The spatial information of landscape pattern from Duolun in 2000 and 2008 are explained and extracted by the ArcGIS and ERDAS software.To support the theoretical basis of utilizing land resources in Duolun,the spatial-temporal dynamic changes of the landscape pattern from 2000 to 2008 are analyzed by applying the basic theory and method of landscape ecology.Results show that the area of forest land increased most rapidly,about 12.09 times than before.The change rate is 1.51% per year.Dominant index increased significantly,whereas fragmentation index and the fractal dimension decreased;the area of sand land decreased about 16107 hm2(accounted for 85.1% of the total sand land area in 2000).The change rate per year is 0.11%.The number of grassland patches was proportional to the fragmentation index.The focus of sand landscape was moving over 21.13 km to the northwest(accounted for 16.4% of the total grassland area in 2004).

Key words: "3S" Technology, Landscape pattern, Dynamic change
