As a lofty mountain Nanshan stretches along the southern border of Kansu Corridor. In past two decades a few discussions had been given by some sdholars about its landforms and its quaternary glaciations. Based upon my field works and recent reports, we know that there are some close Connections existed between tectonic movements, geomorphic cycles and correlative deposits; and, Consequently, they may be mutually explained. according to the analysis of the facies and distribution of Cenozoic sediments, We Know that there a peneplanation developed on the older rocks of Nanshan till pper pliocene, and the red deposits which extended over the Nansban and its adjacent regions Were laden down in the same time. Probably laterly, a crusalt movement, which included mul iple uplifts, initiated. The present geomorphic features of Nanshan are possibly resulted from them. as the dissected summit-levels, the remnants of old peneplains Can be found on many mountain tops today. As regards quaternary glaciations of Nanshan, a more important sign ification should be ascribed to the uplifts of this mountain. Perhaps boh because of the uplifts and the Climatic changs, in Nanshan two glacio pluvial periods had occured in quaternary. When the glaciers expanded all of the mountain peaks and valleys. Later on, the glacio fluvial waters were Carrying much debris and forming sedimentary units, which have been called inland molasse formation, into piedmont plain. a distinct interval, which indicat a true interglacial stage, have been found in that formation. The following table shows the main geological changes of Cenozoic of Nanshan.

河西走廊之南延伸着雄伟的祁连山,在过去20年中一些学者曾对该山的地貌和其第四纪冰期作过一些探讨。根据本人的野外工作及最近的文献资料,我们看到,在构造运动、地貌循环和相关沉积三者之间有着紧密的联系,因而,它们可以相互解释。分析岩相和新生代沉积的分布,我们得知直到上上新世,祁连山进行着准平原化的过程,同时并沉积下红色沉积,它遍及祁连山内外。后来,地壳运动开始,它包括多次上升。现代的祁连山的面貌即是多次上升的产物。古准平原的遗跡,目前可在许多山顶发现。祁连山的第四纪冰期的发生,山地上升占有重要地位,可能正是由于上升和气候变化的同时作用,祁连山发生两次冰期——多雨时期。当时冰川遍及山峰和谷地,稍后,冰融水携带大量碎屑物质带入山足平原形成内陆磨拉石建造的沉积。在该沉积岩系中发现有一清楚的间断,这代表一次真正的间冰期。祁连山新生代的主要地质事件见84页附表。

The Hanjiang storage area of the Danjiangkou Reservoir is situated in the lower reach of the upper Hanjiang River. Naturally, the river flows in mountain gorges in this reach, and the reservoir is consequently of river-type.The Danjiangkou reservoir had been impounded to its normal high level in 1973. During the six-year period of 1973-1980, the inflow discharge was low, the storage level varied in a wide range, and the reservoir had been operated in a low level for a long period of time. Besides, there was the valley geomorphic effect. All of the factors mentioned above exerted a deep influence on the channel changes in the variable backwater zone.According to the analysis of the data collected from the field survey and measurement, the following characteristics of the channel change in the variable backwater zone have been obtained,1.The main factor controlling the change of channel in the variable backwater zone is the reservoir operation, which determines the forms of the deposition and the distribution of the sedimentation, and affects the process of its erosion and deposition.2. The change of channel depends on the process of deposition. The sediment deposited on the river bed at the beginning, and now the cross section is reforming very slowly.3. The fining of bed material composition and the segregation of the sediment size along the stream course are very noticeable.4. The geomorphic conditions, bending, narrow valley and longitudinal sawtoothed profile along the thalweg give a considerable effect on the channel changing.5. The changes of channel intensely affect the flow pattern. Along the stream course, the water level is raised in different degree and the surface slope is reduced. The bars and reefs are submerged and then many local deflecting current, rapids and whirl flow are moderated or even disappeared. As a whole, the flow trends gentle. Some new local flow patterns appear due to the formation of new sand wave movements.6. Every year, the variable backwater zone is subjected to one deposition stage during the flood season and two erosion stages during the level falling period in low flow season and filling the reservoir at the beginning of the flood period respectively. Since Hanjiang storage area is situated in narrow valley with sufficient runoff, steep flood peak and low sediment concentration, the function of the two erosion stages will help to achieve "the long-term operation of the reservoir" , and to erode the pre-stage deposits and thus to reduce the harm from the backwater deposits extending upstream.Finally, this paper discusses some problems of sedimentation in the backwater zone of the Sanxia Reservoir in future.

本文在概述了(1)汉江回水变动区河谷地貌特点及对河道形态的影响,(2)典型的山区河流来水来沙特性,(3)在蓄水后水库调度及淤积分布等三个问题的基础上,分析了建库后汉江干流回水变动区纵横剖面变化,再造床过程中河道形态的演变、年内的冲淤变化及河床地貌等四个方面的问题。由此初步归结出河床演变的几个特点:1.坝前水位的调度是回水变动区河床演变的控制性因素;2.堆积过程是河床演变的主导;3.河床显著细化,泥沙沿程分选强烈;4.库区弯曲狭窄、纵泓剧烈起伏的地质地貌条件对河床变形的影响显著;5.河床变形对水流的影响强烈,同时出现一些新的流态,6.回水变动区每年都经历“汛期淤积、枯季消落冲刷和汛初充水冲刷”的“一淤二冲”的变形过程。最后,简要地讨论了三峡水库库尾泥沙淤积的几个问题。

The carbonate breccias exist widely in the Nanpan river area during the Permian and Triassic periods. According to their petrological chara cteristics and relations with surrounding rocks, we can regard them as deep water carbonate rocks of the debris flow and turbidity current sediments. In this area Dong Wu movement resulted in a lot of faulttrough basins controlled by faults in different directions and obvious difference in lithofacies and topography between the fault-trough and the platform, which was very...

The carbonate breccias exist widely in the Nanpan river area during the Permian and Triassic periods. According to their petrological chara cteristics and relations with surrounding rocks, we can regard them as deep water carbonate rocks of the debris flow and turbidity current sediments. In this area Dong Wu movement resulted in a lot of faulttrough basins controlled by faults in different directions and obvious difference in lithofacies and topography between the fault-trough and the platform, which was very helpful for gravity flow. carbonate to form. The patterns of the carbonate breccias can reflect the paleotectonic geomorphic environment at that time.

南盘江地区二、三迭纪碳酸盐角砾岩分布广泛。据角砾灰岩的岩石学特征及其与围岩地层的组合关系,该角砾岩主要属岩屑流和浊流沉积的深水碳酸盐岩。东吴运动形成了本区多方向断裂控制的断陷盆地,台地和断槽区的岩相和地貌分异十分明显,为碳酸盐重力流发育创造了地质条件。碳酸盐角砾岩的沉积模式是当时古构造地貌环境的具体反映。
