Abstract The paper takes the experimental forest Farm of Beijing West Mountain as an example to study the scenic forest landscape patch type and pattern.Firstly,the scenic forest landscape patches were classified by three levels using the stock map and information of forest resource survey.Then the pattern of each landscape patch type was analyzed based on the application of GIS.The following conclusions were made based on the analysis: 1) The fractal dimension was influenced by three factors from three levels separately.The factors are nature closeness of patterns,using characteristics of victors to the scenic forest,natural attribute of stand.And they are main driving forces for the landscape pattern too.2) The whole landscape pattern was over confined by some patch types,which results in low landscape diversity.3) The continuous decreasing of shrubbery makes it difficult to keep scene diversity and the stability of ecology system.Finally,the main methods to solve the problems were proposed based on these conclusions.1) According to the characteristics of the driving forces for the landscape pattern,the corresponding measures in its management should be taken.2) To those patches with high proportion of Pinus tabulaeformis、Platycladus orientalis and robinia pseudoacacia,it should be regulated their mix proportion,and chosen proper mixed trees,thus its allotment of patch patterns adjusted.3) Reserving the shrubbery patches,especially those have leanness site condition,it is advantageous to raising the scenic diversity and biodiversity.
