流域地貌的分形研究

THE FRACTAL STUDY OF THE DRAINAGE GEOMORPHOLOGY

非线性科学中的分形理论已广泛应用于各个学科。在地貌学研究中,数学—物理方法首先被引入到流域地貌的形成、演化的研究中。分形理论的运用则突破了传统方法的局限,开辟了一条新思路。尽管其运用在流域地貌中才刚刚开始,但人们已感觉到它强大的生命力。本文分析了流域地貌的分形特征,着重介绍了目前国内外已建的各种模型及其最新进展。

The fractal theory, which is one of the nonlinar sciences, has been applied to many kinds of fields. In the field of Geomorphology , mathematical methods are first poured into drainage geomorphology for the study of its forming and evolving. The utilization of fractal theory ,however ,breaks up the limit of these traditional means and creats a new way. Although.it is a beginning to apply it in the drainage geomorphology, its strong vitality has been displayed. This article analyses the fractal characters of the drainage geomorphology and intensingly introduces all kinds of fractal models in the drainage geomorphology all over the world and its latest development.
