岩溶形态系统的分形特征及其机理探讨

运用分形理论，系统研究了构成岩溶形态系统的岩溶地貌、水文网和洞穴系统的分形特征，并计算了分维值，以鄂西岩溶区的地貌小区为例，建立了地表峰体的分维与控制岩溶系统发育的岩性，外源水等因素的联系，揭示了分维的岩溶学含义，进而从岩溶系统介质场结构及岩溶作用过程的非线性动力特征分析探讨了岩溶形态系统的分形机理。

Study on Fractal Characteristics of Karst Morphology System and Its Mechanism

The fractal characteristics of the karst geomorphology, river networks and cave systems are sys-tematically studied for karst morphology system by using fractal geometry, and their fractal dimen-sions are calculated. With examples from several small areas in Western Hubei karst region, a connec-tion between the fractal dimensions of peak features and the control factors (lithology and allogenic water) is established, which discloses the karstological meaning of fractal dimensions. Furthermore, the fractal mechanism of karst system is discussed from the perspectives of medium field structure of karst system and nonlinear kinetic behaviour of harst process.
