| 摘 要： | 沟谷水系具有自相似性的分布特征,可以用分形理论进行描述和研究。该文应用分形理论对巴东斜坡区的沟谷水系特征进行研究,分析水系的发育程度及其所处的地貌侵蚀发育阶段。研究表明,分维值较好地反映了沟谷水系的复杂程度以及水系的切割深度和受构造活动性影响的强弱;巴东斜坡区水系所处流域地貌处于侵蚀发育的幼年期,水系尚未充分发育,河网密度小,河流深切侵蚀剧烈,河谷呈“V”字型。

| Abstract: | The distribution of water system in gullies and valleies has self-similarity,and it can be described and researched by using fractal theory.The water system of Badong slope area is researched by using fractal theory in this paper;the development degree of water system and its development degree of landform erosion are analyzed.The research indicates that the complicated degrees of water system,the cutting depth and the influence of structure activities can be better reflected by fractal dimension value,the erosion development stage of drainage area landform of water system in Badong slope area is in young stage,the water system is not yet developed enough,the drainage density is small, the deep cutting erosion of river is intense and the shape of river valley shows "V" form. |
