摘要
论述了河流水系分形特征，即部分河段在某种程度上包含了整体水系的特征。同时，它具有统计上的自相似性也符合分形几何的概念。另以黄河水系为例所提出的河段分形模型为码尺法模型、盒计数法模型、周长—面积法模型。水系的分形模型为Ｄ＝ｌｎ３／ｌｎ（２ｃｏｓπβ／２），且得到盒维数Ｄ＝１．７３，相关系数为０．９５．
Fractal character of river system is discussed.A part of a river composes chcracters of whole river system on the certain degree,and there is statistical self-similarity.These are in keeping with definition of factal geometry.The yellow River is taken as an example to tllustrate that,the fractal model of river system is D=ln 3/ln (2cos πβ/2),box dimension D=1.73 and the correlation coefficient is 0.95.
