Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were...

Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were formed as early as at the end of the Cretaceous, and then the Yangtze valley was sharply cut down from the uplifting Exi planation surface, and took shape of a series of deep gorges into limestone strata. Investigations have also found that the upper reach of Jinsha River near Dengke once flowed southeastward into Yalong River. Recently the study of river valley geomorphology of the Xizang Plateau reveals that Yaluzangbu River is an antecedent river and that the Daguaiwan gorge in the east of it is neither an elbow ot capture nor a tributary flowing westward to join the Indus as were formerly taken to be. Research into channel geomorphology developed somewhat later, but has made rapid progress. A grade separation system has been put forward for the classification of channel patterns, and attentions given to the dynamic characteristics of the formation and evolution of channel patterns by using C_v(variation factor of the peak discharge) and ρo/ρp(the ratio of incoming sediment concentration to the sediment carrying capacity in a channel) as indexes to indicate the stabilities of different channel patterns and the mutual transformations among them. By analyzing many rivers with heavy sediment concentration, a wandering index has been derived. Rivers having the value of greater than 5 are called shifting and less than 2 unshifting. In the middle and lower Changjiang, the latest research of meanders and relatively stable channel patterns has had some results. Observations and simulation experiments con the fluvial processes of the channels above and below reservoirs reveal that the channel of Huanghe below Sanmenxia Reservoir, after baving been washed by clear water, still remains shifting for a long time, and the headward silting end of Weihe channel above the reservoir stretches out or draws back within a certain limit. The investigations of deltas point out that since the Quaternary the mouth of Changjiang has been extending southeastward and that there exist imbricate fossil deltas under the water. As for the Huanghe delta, it is evident that since the diversion of the river course in 1855, a new delta with an area of 5,450 km~2 has been built up. Penetrating research has also been made on the geomorphological features and processes of the evolution of Qiantang River. Field survey discovers that the main source of Changjiang is Tuotuo River rising in Geladandong snowberg, and that of Huanghe is Kariqiu River originating in Geshigeya Mountain of the Bayankala Mountains.

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。

Dujiangyan Irrigation Project was built on the main course of the Minjiang River at Guanxian County in the Sichuan Province 2200 years ago. This ancient project is still being in service at present. The total irrigated area has been increased from 130,000 hectares before liberation to more than 570,000 hectares nowadays. In order to meet the increasing demand of water development of the area, it is necessary to reconstruct the Dujiangyan headwork. The disposal of the pebble-gravel bed load is the key problem...

Dujiangyan Irrigation Project was built on the main course of the Minjiang River at Guanxian County in the Sichuan Province 2200 years ago. This ancient project is still being in service at present. The total irrigated area has been increased from 130,000 hectares before liberation to more than 570,000 hectares nowadays. In order to meet the increasing demand of water development of the area, it is necessary to reconstruct the Dujiangyan headwork. The disposal of the pebble-gravel bed load is the key problem in the reconstruction of the project. The function of the Dujiangyan Diversion Works(without diversion dam) for preventing sand and gravel entering the intake has been analysed. Based on model study and analysis of operation experience of the headwork, some engineering measures have been recommanded as to build a diversion dam to deal with the disposal of gravel bed load. Experiences dealing with bed load problem of water conservancy and hydroelectric power projects in southwestern China have also been summarized. By considering merely a part of the gravels of the bed is movable, a modified formula of gravel bed load transport is presented.

都江堰是我国古代劳动人民创建的一项大型水利工程,沿用至今。为扩大灌溉及综合利用效益,需要改建都江堰工程。由于推移质泥沙的处理问题使都江堰工程改建几经周折。本文分析岷江及都江堰工程特点,分析讨论建闸及都江堰改建问题,及探讨卵石推移质输沙率的计算方法。

In this paper,diversion works built in the ancient time are briefly described and sediment problems encountered are pointed out. Discussions are emphasized on the layout of structure, the engineering measure of sediment control and the effect of diversion and desilting of different types of low-head diversion works built in different areas in the recent thirty years. Experimental studies in this field are also given in the paper.

本文简要地引述了我国早期的引水灌溉工程,指出了仔在的主要问题(泥沙问题).着重论述了近三十年来各地修建的各类低水头引水枢纽的布置形式、防沙措施和引水防沙效果,以及目前试验研究的现状.
