摘要: 通过闽江流域水系分形和太湖地区癌症分形研究,阐述了河流、水系和社会经济现象具有分形特征,说明分维定量描述地理现象的优点.并且在遥感图像处理上应用分形特征,达到信息压缩,重构图像精度高的目标.种种试验表明分形概念十分有助于地理研究.

Abstract: The study on the fractal of the Minjiang River system and the cancer fractal of Tai-hu Lake reveals that rivers,water systems and social economic phenomena have fractal features,showing the merits of fractal dimension and quantitatively describing geograph-ic phenomena. And the application of fractal features to remote sensing image processing can reach the goal of information compressing and reconstituting image accuracy. These experiments show that fractal theory is very useful to geographic research.
