中文摘要	在GIS/RS的支持下, 运用分形理论和景观生态学原理, 对阜康绿洲土地利用类型图斑的周长、斑块边缘密度和斑块形状指数的标度-频度关系进行了定量分析. 结果表明: ① 阜康绿洲土地利用类型斑块周长、斑块边缘密度和斑块形状指数的标度-频度双对数关系显著, 相关系数均超过0.9, 呈高度负相关分布; ② 阜康绿洲土地利用类型斑块周长、斑块边缘密度和斑块形状指数存在标度-频度的分形关系, 不受所选统计标度的影响, 这为进一步分析土地利用类型周长-面积的分维数, 研究斑块的复杂性与稳定性打下基础; ③ 以上分析可以增加对分形理论的理解与应用, 同时也为区域可持续开发利用土地及土地管理与设计提供参考依据.
英文摘要	Under the support of RS and GIS means, in this paper the scale-frequency relations between the patch perimeters, patch edge densities and patch shape indexes of all the land use types in Fukang City, Xinjiang are quantitatively analyzed using the fractal theory and some basic theories in landscape ecology. The results show that there is a significant log-log relationship among them, all the correlation coefficients are higher than 0.9, and there is a significant negative correlation between the scale and frequency. The fractal relationships between patch perimeters, and patch edge densities and patch shape indexes of all the land use types in Fukang City are not affected by the selected statistical scales, which provide a base for further analyzing the perimeter-area fractal dimensions of all the land use types and studying the complexity and stability of patches. The number of the patches of the land use types is abundant, and the maximum patch perimeter is longer than 400 km. The results reveal that there are only a few dominant land use types in Fukang City. Both patch shape index and patch edge density are high, and the land use types are relatively complex due to human activities. All these analyses above promote the application and comprehension of fractal theory, and provide the references for region sustainable land exploitation and utilization and land management design.
