Abstract The land use structure in Gansu province was studied from aspects of "patch-corridor-matrix" pattern and landscape ecology index. The result showed as follows: ①There are four types of land use regionalized by base pattern: a. cropland type-including Tianshui, Dingxi, Pingliang, Linxia; b. woodland type-including Longnan; c. grassland type-including Lanzhou, Baiyin, Zhangye, Qingyang, Gannan; d. unused land type-including Jiayuguan, Jinchang, Jiuquan, Wuwei. ②The land use structure types have obvious in the spatial distribution under the control of the naturally geographic differentiation. ③The heterogeneity of land use structure of Lanzhou, Jiayuguan, Jinchang, Jiuquan, Zhangye, Gannan is homogeneous heterogeneity, and that of Baiyin, Tianshui, Wuwei, Pingliang, Qingyang, Linxia belongs to heterogeneous heterogeneity, but the change tendency is generally not obvious. ④The maximum patch did not change obviously in time, although change remarkably in space. ⑤The patch of the land use structure were garden plot in all cities, and they all increased less except that of Pingliang and Tianshui have obvious increasing trend. ⑥Woodland is the main patch with the greatest change in space-time, followed by cropland then grassland.
