摘要: 把分形理论和熵有机地结合起来,系统地研究喀斯特流域和非喀斯特流域的干谷水系、常流水系和地下水系的分形结构及其熵的地貌意义,初步揭示了流域水系的形成与地貌发育演化之间的关系,认为仅利用水系的分维值来分析地貌演化是不够的,还应考虑流域水系的熵值变化.

Abstract: Fractal theory has been extensively applied to research the stuctural charater of drainage basin, but it seldom combines with entropy studies karst drainage. This paper studies systematically the fractal character and geomorphological significance of entropy in karst dry valley system, fluvial river system and undergound drainage, and compare with non-karst drainage basin. We think that fractal and entropy are important parameters in hydrogeomorphologic system and could be used to analyse structrual charater of karst drainage and evolution of karst hydrogomorphology.
