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。

关 键 词:遥感  面状水体  分维  面积-周长法(小岛法)  巢湖

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...
Keywords:remote sensing   surface-water fractal dimension   Area-Perimeter Method (small island means)   Chaohu
