摘要: 以Mandelbrot的分形理论为基础,较详细地推算了图形面积与周长的分数维公式,并以农牧交错带典型沙漠化区内蒙古奈曼旗尧勒甸子村沙区土壤图为例,对沙漠化的现状及发展趋势进行了分数维分析,得到了较好的效果,认为该理论在沙漠化定量研究中具有很大的应用潜力。

关键词: 沙漠化, 分数维, 定量研究, 应用前景

Abstract: The application equation and the result of desertification quantitative research were gave in this paper, based on the graphic fractionation of Mandelbrot, with the soil map in the region of farming and grazing edge zone , Yaoledianzi village , Naiman county as an example. For the good result, this theory will be used widely in the future in desertification quantitative research.

Key words: Desertification, Fractionation, Quantitative research
