摘　　要：以1998年和2007年2个时相的Landsat TM影像为数据源,利用面向对象的分类软件eCognition对影像进行分类,得到两时相的土地利用图,之后做出土地利用转移矩阵,分析该区各类土地的转移情况。结果表明,1998～2007年该区土地利用变化较大,主要表现为:建设用地、林草地和其他用地呈增加趋势,其中建设用地增加最快,年增长率达8.47%;耕地、煤矿用地和水域面积不断减少,其中耕地面积减少最多,减少面积达7090.71hm2。造成该区建设用地不断增加的主要原因是人口的增长、经济的发展以及政策法规的推动等。另外,煤矿开发与复垦也是造成该区土地利用变化的重要原因。Based on two temporal TM images of Fuxin mining area for both 1998 and 2007, the study area was classified by object-orlented classification in eCognition. According to the results of land use, the changes were quantified by the way of making conversion matrix of land use. The results showed that the area of the construction land, forest-grass land, and others increased, on the contrary, the area of farmland, mining area and water body decreased. The increased speed of the construction area was the fastest, and the value reached 8.47%. The decrease area of farmland was the largest, and the value reached 7 090.71 hm^2. The main reasons of the change were the growth of the population, the development of the economic, the force of the policies and so on. In addition, the exploitation of the mining area and the reclaim of the subsided land made the mining area converted into farmland.
