摘要: 从自组织系统思想出发,提出了人地关系的基本特性(非决定性、不对称性和非线性),通过逻辑斯蒂方程的数学变换,分析了人地非线性相关作用的混沌特征,进而讨论了人地关系的分形(多分维)性质。基于混沌过程与分形结构的因果关系,指出:地球表层系统中的人文分形景观乃是人地非线性关系的混沌作用所致。

Abstract: The studies on man-land relationship will not only contribute to unifying geographical theory by getting rid of dualism,but also are great practical value to solving problems on environment,resources,population,and so on.Being based upon the idea of systematic self-organization,the papar advances a new point of view of man-land relationship with non-determinity.The non-linear interaction between man and land is analysed dynamically by means of logistic map which can reflect relationship between a system and its environment.After discussing the chaotic course in the interaction,the authors point out the multifractal nature of man-land relationship.The conclusion is that fractal structure is a good structure of nautre,and chaotic course often leads to this kind of structure.The chaotic course is the very cause which results in human fractal landscape on the surface of the earth.
