The study of landscape pattern is the main content of landscape ecology. The landscape metrics method is an important method to study landscape pattern and is widely used landscape ecology. In the process of its calculation, landscape patches are regarded as planar existence. However, the actual landscape and its patches are all three-dimensional, and the calculation using only the plane will ignore some features of the landscape, so that the calculation results may be biased. Therefore, in order to restore the three-dimensional characteristics of the landscape, this paper tries to introduce the method of calculating the specific surface area of the landscape in order to add a new, more accurate method for the study of landscape pattern. The results show that the specific surface area of farmland is the largest and its effect on the ecosystem is the most significant. At the same time, if the height of patch type (such as buildings) changes, the specific surface area value will change accordingly, and the importance of each plaque will also change. However, the results calculated by the landscape index method cannot reflect the corresponding changes.
