| Abstract: | At the study area of Xigu District in Lanzhou City, using RS & GIS as tools we apply Diversity, Dominance, Fragmentation,
Isolation and so on to study the quantitative, fractal and spatial characters of landscapes structures in the four sub-regions
divided by the morphological features. Using the Fractal Theory to establish the fractal structure models, we analyze the
complexity and stability of various landscapes distribution with fractal dimension value. The spatial distribution characteristics
of landscape mosaic structure are also expounded. At the end of the paper we discuss the relevant problems on the main factors
which control and effect on the spatial pattern of landscapes as well as on landscape optimization and management.
