| 摘 要： | 通过对2000年2月的研究区ETM＋遥感影像光谱特征进行分析，利用修正的归一化差异水体指数（MNDWI）与谱间关系法提取研究区面状水体形态信息，使用小岛法计算面状水体的分形维数，得到巢湖流域全区面状水体的总体分维D0=1．2776，及以主要河流所划分的各子区的分维值：南区D1=1．2800，西区D2=1．3032，北区D3=1．2376。反映了研究区各子区地理环境与人类活动的差异。

| Abstract: | On the Base of analyziing spectroscopic characterization of Landsat ETM+ remote sensing data on February 29 in 2000, combined with information extraction of the surface-water body by using relationship between bands and correction of MNDWI, this paper calculated fractal dimension of the surface-water about the whole basin and its sub-region by using small island means. The result showed that the whole basin's fractal dimension of the surface-water is 1.2776 (D0=1.2776); values in the southern part of this a... |
