【Abstract】 Hydrology and geomorphology in karst drainage area interact with each other and form an organic system, as is the special case in small karst drainage. This paper, by using a mathematical method of tendency surface analysis, is to reveal the evolutional rgeularity of geomorphology and the alteration of river system in this area, and points out that the constant down cutting of Boyu Mugong river, which results in a lowering of baselevel, has a sighificant effect on the evolution of geomorphology and river system.更多还原
