以西部典型的工业欠发达城市四川省南充市为例，基于全国第二次土地调查数据，运用景观生态学理论和数理统计方法，选取多样性指数、均匀度、优势度、破碎度、分离度等景观格局指标，研究其郊区土地利用结构的数量特征；运用分形理论建立地类分布形态的分形结构模型，以分维数和稳定性指数为依据分析各地类分布形态的复杂性与稳定性。结果表明：嘉陵区主要地类多样性及均匀度指数较小，优势度较大，土地利用结构较不均匀，优势地类为耕地；各地类破碎度与分离度排序相反，耕地最破碎且最集中，水域破碎度最小且分布最分散；分维数和稳定性指数表明地类分布形态较不规则且较不稳定。

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 application of landscape ecology theory and mathematical statistics,selecting the diversity index,evenness index,dominance index,fragmentation such as separation,we studied the quantitative characteristics of the land-use structure in the suburbs. We 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 and the dominance index is larger. 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,while the water area is the least broken and the most scatter land-use. Fractal dimension and stability index show that the land-use distribution form is more irregular and less stable.
