The land-use pattern is one of the key study areas of the utilization of land resource、landscape ecology and the sustainable development, which has important implications for other areas such as the ecological environment, land-use, and isolation. Based on the second national land survey data, the applicat ion of landscape ecology theory and mathematical statistics, selecting the diversity index, evenness index, dominance index, fragmentation such as separation, we have studied the quantit ative characteristics of the land-use structure in the suburbs. We have created a kind of distribution in the fractal structure model by using the fractal theory and have analyzed the complxity and stability of the types of land distribution, based on fractal dimension and stability indexes. The results showed that: the diversity and evenness index is smaller, the dominance index is larger, so that the land-use structure is uneven and the advantage land-use is cultivated land. The order of the separation is contrary to the fragmentation. The cultivated land is the most broken and the most concentrated land-use as well as the water area is the least broken and the most scatter land-use. Fractal dimension and stability index shows that the land-use distribution form is more irregular and less stable. The study conducted an analysis of the land-use structure of the urban in the underdeveloped cities, providing a reference for the ecological environmental protection, the rationalization of land-use.
