摘要
本文对矩形流域的斯特拉勒积分值S、信息熵值H及河谷纵剖面形态指标N进行了对比研究,把N作为矩形流域地貌发育阶段的指标。同时还利用滇西北三江(金沙江、澜沧江和怒江)流域的资料,对以上各指标进行了验证;得出在侵蚀循环中所处发育阶段的信息和侵蚀流域稳定性的信息。
This paper compares and studies the strahler integral value S, theinformation entropy valuq H and the shape index N of river gully longi-tudinal section in rectangle basin,considers N as the index of therectanglebasin geomorphy developing stage. At the same time, this paper utilizesthe information of the three rivers (Jinsha River, Lancangjiang Riverand Lujiang River) basin in the northwest of Yunnan, demonstrates theindexes above all,at last draws the information of the developing stagein the cause of eroding circle and the information of the stability inerosional basin.
