摘要
本文应用遥感技术,结合野外调查,研究了曹渡河流域水系的分形分维,初步建立起岩溶区流域水系的计算机扫描程序。首次推算出岩溶地貌斜坡带曹渡河流域的分数维值为1.54。通过与拉平河、平河两条小流域的对比研究,初步总结出不同地貌类型、不同地貌形态、不同地质构造和水文地质条件与水系分数维的关系。
This paper probes into the drainage fractal and fractal dimensions deeply. And the computer scanning programme of valley has been preliminarily built up in the karst region by means of the remoting sensing technology and combing with the field invcstigation. The drainage fractal dimension value is estimated as 1.54 for the first time in the zone of karst geomorphologic slope——the Caodu River. The author summarizes the feature of fractal demensions in the varying geomorphologic types liminarily, and the varying geomorphologic shapes as well as the different geological structure and hydrogeological environment by study of contrasting the Laping River and the Pingli River, (the two small valleys)the Caodu River.
