The thesis was made of a systematic analysis to the vegetation landscape elements and patches. With help of ArcView3.2, the vegetation map was processed and the data of the six vegetation landscape elements were obtained.The diversity of landscape elements in this area is rather low while the dominance rather high. It is the key reason for the low diversity that the difference in the area of elements is rather great and only a few elements are dominant.The degree of dissociation index along with the mottling density the tendency which increases has increases; But the broken index increases along with the mottling density has reduced the tendency.The shape index tends to increase with growth of the patch area. The shape indices of the shrub landscape,the farm landscape and ground of fodder grass landscape are in under two. The shapes of them are close to rotundity. The fractal dimension of lawn landscape elements in Zhaosu is rather low, which show that the lawn landscape is interfered quite little by human activities.Summarily, we can conclude that the rather big difference between the areas of each landscape elements in Zhaosu ,the quit low diversity, the rather high degree of dominance as well as the influence of human activities are all the problems to be solved in the future management of the Zhaosu.
