摘　　要：分形是局部和整体以某种方式相似的形。不同的土地类型作为一种地学特征反映在遥感图像上,其像元亮度—面积模式亦符合一定的分形理论。可以利用分形理论的求和法进行不同土地利用类型的划分,并且此方法可以在一定程度上弥补监督分类中地物样本量选取量影响分类结果的不足。以广州番禺区2003和2009年的土地利用类型划分为例,利用ETM/TM数据基于分形的方法将林地从植被背景中分离,将坑塘等从水体背景中分离,将未利用土地类型从整体背景中分离,分类精度分别达到94.6685%(2003年)、91.1384%(2009年),并探讨了该地区土地利用变化的相关问题。Fractal is locally similar to the whole in some way.Different types of land as a feature of goesciences is reflected by the remote sensing images,brightness—area of the pixel mode is also in line with the fractal theory.The paper via the sum method of fractal theory distinguish different land use types,and this method can make good of classification results for ground samples quantity selected in supervised classification in a certain extent select.Taking land use classification in 2003 and 2009of Panyu Guangzhou as an example,the paper separated from the background of forest vegetation in the pond,and the water be separated from the background,the unused land type was isolated from the whole background using ETM/TM data based on fractal method.Finally,respectively total classification accuracy of different types of land are 94.6685%（2003）,91.1384%（2009）,and probes into some problems related to land use change in this area.
