摘要
以扇形沉积体的分形研究为例，针对分形理论在地学应用领域中存在的一系列值得注意和深入探讨的问题，如分形的层次、尺度及线性无标度区、分维数测定方法的选择、分形动力学与分形重构、构造分形Ｄｓ与结构分形Ｄｔ的关系、分形模拟和预测等，进行了分析和讨论，并强调指出，在地学领域中基于非线性动力学理论和非线性数学方法基础之上的分形动力学模拟具有重要的理论和实际意义。
Fractal theory is widely and deeply applied in geological field,but there are some factors affecting the real application.These problems are:layers,scale,and linear non mark district of fractal,choose of methods determining fractal dimension,fractal dynamics and fractal restructure,the relation of structural fractal and textural fractal,fractal simulation and its prediction etc.The paper discuss and analyses these factors,and point out that the fractal dynamics modeling is significant in theory and application based on non linear dynamics theory and non linear mathematics methods in geology field.
