Accurate and rapid monitoring of vegetation cover conditions is a key factor in land cover remote sensing monitoring in mountain areas of Beijing. Based on TMimagery data, the mapping technology of FCDmapping model was applied to Mentougou district of Beijing. The results show that the approach of remote sensing mapping is of good practical value. The accuracy of vegetation coverage estimated by FCDmapping model is some 95%, suggesting that the method is suitable to mountain areas. Moreover, the results computed from a landscape pattern analytical program FRAGSTATSby analyzing patch-sizes, number of patches, fractal dimensions and cohesion indices indicate that vegetation covers are main components of the present land cover in Mentougou of Beijing. Analyses of all these indices demonstrate that the ecological-environmental system in Mentougou mountain area is stable. The spatial structure analysis can help to identify the spatial distribution and structure stability of the vegetation coverage, and hence it is another important factor in the ecological system evaluation of Beijing mountain areas.
