三十年来我国河流地貌的研究主要为河谷地貌、河床演变和河口三角洲。其中,河谷地貌研究提出了长江三峡在白垩纪末已经形成,其后从鄂西期夷平面下切于石灰岩层内而形成一系列峡谷。发现金沙江上游在邓柯附近曾向东南流入雅砻江。论证了雅鲁藏布江横贯喜马拉雅山脉的为先成河,并非由于河流袭夺的结果。河床演变的研究提出了游荡指标>5为游荡,<2为非游荡。以C_v和ρ_o/ρ_p两值作为河型稳定和转化的指标。对三门峡、丹江口等水库上下游的河床演变进行了观测和模拟试验。研究了长江、黄河和珠江等三角洲的形成演变,提出了新的见解。经过实地考察发现长江的正源为沱沱河,发源于各拉丹冬雪山;黄河的正源为卡日曲,发源于巴颜喀拉山脉的各式各雅山。
In the past three decades, the study of river landscape in China mainly includes river valley landforms, river bed evolution and estuarine delta. Among them, the study of valley landscape proposed that the Three Gorges of the Yangtze River had been formed at the end of Cretaceous, and then cut into a series of canyons under limestone from the plane of western Hubei during the Cretaceous period. The upper reaches of the Jinsha River were found to have flowed into the Yalong River to the southeast near Dengko. Arranging the Yarlung Zangbo River across the Himalayas as a precedent, it is not the result of the rivers being captured. The study of river bed evolution has proposed that wandering index> 5 is wandering, <2 is non-wandering. C_v and ρ_o / ρ_p two values as river stability and conversion indicators. The evolution and evolution of the upper and lower reaches of the Sanmenxia and Danjiangkou reservoirs were observed and simulated. Studied the formation and evolution of the delta such as the Yangtze River, the Yellow River and the Pearl River, and put forward new ideas. After field investigation found that the positive source of the Yangtze River is Tuotuohe, originated in the Mount Hudan winter snow; the positive source of the Yellow River kariga, originated in the various valleys of the Bayan Kara mountains.
