摘　　要：利用1987年、2000年、2005年和2010年4期多伦县TM影像,结合RS与GIS技术手段,运用综合土地利用动态度、单一土地利用类型动态度、马尔科夫转移矩阵和景观指数等方法,分析了内蒙古多伦县近23年来土地利用景观格局变化.结果表明:1987～2010年,多伦县除了未利用地面积大幅度减少外,耕地、林地、草地、居民点、水域面积均有所增加,多伦县土地利用动态度在2005～2010年最大,2000～2005年次之,1987～2000年最小;多伦县景观基质为草地景观,各土地利用类型及景观格局指数均发生了重要变化,林地明显增加,未利用地呈明显减少;除了人居景观受人类活动的影响呈增强趋势外,其他各类土地利用景观受人类活动的影响均呈下降趋势;景观异质性上升,景观破碎化程度增加;在整个研究期间,各土地利用类型向同类型分散、不同类型间邻近、各类型间彼此混杂的方向发展.The purpose of this study was to analyze the country in the past 23 years＇ land utilization and landscape pattern changes based on the 1987,2000,2005 and 2010 four period TM images of Duolun area,combined with RS and GIS technology,used the comprehensive dynamic degree of land utilization,and the single land utilization type dynamic degree,Markov transition matrix and landscape spatial pattern research methods.The results showed that from 1987 to 2010,the farmland,forest land,meadow,residential areas,water area are increased besides the unused land is greatly reduced of Duolun County.The maximum rate of land utilization annual dynamic change of Duolun County is during 2005～2010;2000～2005 period comes second cycle;the rate of land utilization during 1987～2000 was reached the minimum;the landscape matrix of Duolun county was grassland landscape,and all types of land utilization and landscape pattern index were changed,woodland increased significantly,unused land was markedly reduced;besides human habitat landscape influenced by human activity was increased,other types of land utilization landscape influenced by human activities was declined;the landscape heterogeneity on the rise and the degree of landscape fragmentation is increasing;during the whole study period,the land utilization types tend to disperse to the same type and different types between adjacent,various types of mixed each other between the direction of development.
