Landscape pattern is a main content of landscape ecology which plays an important role in biodiversity conservation. In this paper,the landscape diversity,mean patch fractal dimension and landscape evenness were calculated to analyze the spatial structure and dynamic character of landscape pattern in Qingxiushan mountain area in Nanning city. The result indicated that human activities were the determining factors of landscape pattern. Through comparing natural features and features of human activity with the landscape indices,we found that the determining factors in different of landscape districts are not the same. Landscape diversity and evenness of Qingxiushan Mountain increased with time. The phenomenon which one of the landscape type occupied a dominant position has not been found. Except the Conifer and Broadleaf mixture forest,the number of patch of each landscape increased with time. The shape of patch was more complex in 1985,since then,it became more regular with time. So the forest in Qingxiushan mountain was disturbed intensively by human activities.
