摘要
根据1986年和2000年的TM影像数据,利用GIS技术和景观结构分析软件FRAGSTATS,分别从类型和景观两个水平上对比研究了石羊河流域中游武威绿洲和下游民勤绿洲的景观格局及其动态演变,并利用转移矩阵对中下游绿洲土地利用格局的空间转化趋势进行了比较分析。
Based on the TM image of Wuwei and Minqin oases in middle and lower reaches of Shiyang rivver in
1986 and 2000. Using GIS technique and landscape structure analysis program FRAGSTATES. It calculated and
analyzed the landscape metrics and their changes of studying regiong at class metrics level and landscape metrics
level respectively. And also the changes of land use patterns in two oases were compared by caculatin transforma-
tion matrixes of landscape mosaics.
