| 摘 要： | 利用SPOT遥感影像得到的榆中县土地数据，应用景观生态学原理和方法，分析了榆中县土地利用的景观格局。结果表明：榆中县20个乡（镇）土地利用的多样化指数相差较大，其中以兰州市区附近乡镇的多样化指数较大，即土地类型较多；土地利用形状指数小，乡（镇）之间相差较大；各乡镇之间分维数差异不明显。土地利用集中化程度和土地利用类型数量组合数据显示，榆中县土地利用类型以未利用地和耕地为主。

| Abstract: | By using land-use data from SPOT remote image of Yuzhong county,and the methods and principle of landscape.This paper analyzed the landscape pattern of land-use of Yuzhong county.The results showed that between the diversity index and shape index of land-use 20 small towns are very different in Yuzhong.The bigger diversity index of small town is near the Lanzhou city than the others.The shape index between those villages are different too,and its small.The fractal dimension are not obvious different among those villages.The result also showed that the majors land use type of Yuzhong are unused land and cropland from the land-use centralize degree and combination of land-use types. |
