| 摘 要： | 利用兰州市 1 980、1 995、2 0 0 0年三期TM遥感数据 ,将土地利用分成 6种类型 :城乡工矿和居民地、荒地、林地、水域、耕地和草地。利用GIS空间分析技术的空间叠加方法得到兰州市 1 980 - 1 995年和 1 995 - 2 0 0 0年土地利用变化情况以及土地利用转移矩阵。结果显示 :城乡工矿以及居民地面积在 1 980 ,1 995 ,2 0 0 0年的概率分别是 9.75 % ,9.5 5 % ,1 0 .1 8% ,总体上是增加的 ;林地面积在 1 980 ,1 995 ,2 0 0 0年的概率分别是 8.5 3% ,8.44% ,8.5 9% ,有增加趋势 ;草地面积在 1 980 ,1 995 ,2 0 0 0年的概率分别是 5 3.5 9% ,5 4 % ,5 3.35 % ,总体上是在减少 ;耕地面积、水域面积也有明显的减少。

| Abstract: | The landuse was classified into six types:urban-land ,bareland, forest, water-body, crop-land and meadow according to the remote sense(RS) data from the TM imageries of 1980,1995 and 2000. The convertion matrix for land use change and land use of lanzhouwere obtained by using "overlaying"of GIS specialanalytic techniques. The area probability of the urban-land type in the 1980,1995 and 2000 were separately 9.75%,9.55%,10.18%.As a whole, urban-land areas were increasing. The area probability of the forest type in 1980,1995 and 2000 were separately 8.53%,8.44%,8.59% and the forest areas shwoed increasing trend. The area probability of the meadow type in 1980,1995 and 2000 were separately53.59%,54%,53.35%and meadow area decreased; crop-land and water-body types decreased markedly. |
