| 摘 要： | 综合应用RS和GIS技术，以泸定县泸桥镇为研究区，根据国家二级地类分类标准解译遥感图像，然后在此基础上，借助分形理论对泸桥镇土地利用类型进行分形分析与研究。结果表明：耕地、园地和住宅用地的斑块形态较为简单，处于稳定状态；未利用土地分维值最大，斑块形状较为复杂，处于不稳定状态。

| Abstract: | Taking Luqiao town in Luding county as the research region by using RS and GIS comprehensively. According to the country＇s secondary category classification standard interpretation. The thesis makes a statistical analysis and study on land use types in Luqiao town with fractal theory on the basis of the Luqiao Town land use chart. The results indicate that the structures of plantation, garden plot and residential area are simpler and at relatively stable state, the fractal dimensions of unused land are the largest and its stability are lower than others. |
