%X With the forest type map(1:50000) of Linkou Forestry Bureau as the basic information,and by using ArcView 3.3 and Fragstats,this paper analyzed the landscape patterns in this Bureau from the aspects of overall landscape properties,landscape fragmentation index,landscape shape index,perimeter-area fractal dimension,and mean nearest neighbor distance.The results showed that the overall landscape was dominated by forests(56.74%),and residence and farmland also had a high proportion of area.Swamps,shrubs,wastelands,rivers,harvested(and burned) areas,and bare lands were distributed sparsely.Artificial coniferous forest(40.47%) and natural Mongolian oak forests(20.96%) dominated the forest landscapes,with relatively lower fragmentation,comparatively complicated patch shapes,higher perimeter complexity,and comparatively centralized patch distribution.The area of plantation landscapes was nearly equal to that of natural forests,but the plantation landscapes had a higher degree of fragmentation,simpler patch shape,and relatively concentrated patch distribution.Softwood forest patches and hardwood forest patches occupied 11.89% and 7.38%,respectively.The forest landscape in this Bureau was heavily disturbed by anthropogenic activities,and stand structure was unreasonable.Patch structures should be adjusted to meet the need of sustainable forest management.
