摘　　要：根据广东省韶关市第二次全国土地利用调查数据,利用分形理论,分析了韶关市3个辖区土地利用类型的空间镶嵌结构复杂程度和稳定性,并揭示出各土地利用类型的空间分异。结果表明,林地的斑块空间镶嵌结构复杂程度最小,稳定性最强;城镇村居民点的空间镶嵌结构复杂程度较小,稳定性较强;耕地、园地、草地和未利用地空间镶嵌结构复杂程度较大,稳定性较差;采矿用地、交通用地和水域空间镶嵌结构复杂程度大,稳定性差。韶关市各土地利用类型空间镶嵌结构复杂程度和稳定性的空间分异明显,空间差异最大的是交通用地,其次是耕地、水域、草地、未利用地、林地、城镇村居民点和园地、采矿用地空间分异最小。According to the second national land use investigation data in Shaoguan City, Guangdong Province, based on fractal theory, this paper analyzed spatial structure of land use and calculated fractal dimension and stability in Shaoguan. And then the paper revealed the various types of land use spatial differentiation. The results showed that the mosaic structure of forest patches space complexity of the smallest, strongest stability. Mosaic structure of urban space is small village settlements complexity, strong stability. Large arable land, gardens, meadows and unused land, the degree of spatial mosaic structure is complex, less stable, mining land, traffic land and waters to a large extent the structure of the complex mosaic of space, poor stability. Space for each land use type space mosaic structure and stability of the complexity of the obvious differences, the biggest difference is the space transportation land, followed by farmland, water, grassland, unused land, forest, urban village settlements and garden, mining and land space differentiation minimum.
