Abstract: In order to promote the ecological restoration and the more reasonable designing of landscapes in Subaohe catchment, based on the technology of RS and GIS, the ecology principle of landscape was applied to the preliminary analysis of landscape pattern and fragmentation in Subaohe catchment from the angle of patch characteristics of landscape elements there. The results showed that: coniferous forest, broad-leaved forest, shrub, grass and farmland were five main components in Subaohe catchment. The total area and perimeter proportion of the five landscapes accounted for 84.51% and 73.98% of the total in the district, respectively. Of all the different kinds of landscapes, the order of the area was consistent with the perimeter order, while the distribution of the area and the perimeter elements were very uneven in each landscape especially in broad-leaved forest, road and channel. The fragmentation of the landscape which suffered from natural disasters or human disturbance was higher than that covered with vegetation. Different landscapes have different shape, as road and channel were irregular mostly while back scarp was close to square.
