Abstract: In order to research the characteristics of scenic forest landscape patterns and further study the correlations between the ecosystem processes, such as the landscape pattern, and the factitious jamming, this paper took the Beijing Xishan Mountains Experimental Tree Farm as the research area, divided the scenic forest landscape patterns into three levels, and then took quantitative analysis on each level.The results were as the followings:1) the panorama landscape of the three levels were all granule structural landscape.2) The mixed forest patches on the second level and the Fraxinus chinensis patches on the third level both had good connectedness and integrated types.This is beneficial to maintain the biodiversity of the scenic forests as a whole.3) The factors having the biggest effects on the characteristics of the patch shapes in three levels were nature closeness of patterns, using characteristics of victors to the scenic forests and natural attributes of stand.4) The panorama fragmentation degree of each level in the research areas was low.At the second level, the underage-forestland and assistant woodland had the highest fragmentation degree, and the conifer was the lowest.The patches of Prunus armeniaca and Acer truncatum had the highest fragmentation degree at the third level, and Platycladus orientalis was the lowest at this level.5) Some patch types (such as the conifer patch at the second landscape level, along with Pinus tabulaeformis, Platycladus orientalis and Robinia pseudoacacia at the third landscape level) had a large acreage and concentrated distribution.All patch types had a low uniformity.6) The shrubbery in the ecological vulnerable region was reserved.
