以阜康市为例,在遥感和地理信息系统技术的支持下,利用土地利用类型结构的分形模型,计算了阜康市各土地利用类型斑块的分维数和稳定性指数.结果表明:阜康市各土地利用类型斑块的面积-周长双对数关系显著,即阜康市土地利用类型空间分形结构客观存在;各土地利用类型图斑的分维数存在差异,分维数最大的是城乡工矿居民用地,为1.409 6,最小的是耕地,为1.098 6;在各土地利用类型的稳定性指数中,耕地的稳定性指数最高,为0.401 4,城乡工矿居民用地的稳定性指数最低,为0.090 4;各土地利用类型的平均分维数为1.240 3,偏离随机运动值较大,说明土地利用类型总的趋势是比较稳定的.

Taking Fukang City as an example, with the support of GS and GIS, the fractal dimension and stability indices of land use patches were calculated by adopting fractal model of structure of land use types. Results showed that the double logarithm relationships between the area and perimeter of patches of land use types were significant, that is to say, spatial fractal structure of land use types in Fukang City was existed objectively. Fractal dimensions in different types of land use patches were different. The land for urban-rural industry, mining and residents had the largest fractal dimension (1.409 6), and the cultivated land had the smallest (1.098 6). The stability index of cultivated land was the largest (0.401 4), and the stability index of the land for urban-rural industry, mining and residents was the smallest (0.090 4). The average fractal dimension was 1.240 3, which deviated from the random motion value greatly. It showed that the general trend of land use types was relatively stable.
