As the surface altitude increases, the water level and the imbedded water level decrease, and is lowest in Betula ovilifolia－Carex schmidtii－Sphagnum palustre community, which may be firstly caused by the distribution of the hummocks of Sphagnum palustre, which is powerful in holding water, and this has cushion function on the change of water level; On the other hand, it may be caused by it's position near the hill, the runoff from the hill may supply the district, so that the change extent of water level at a certain extent minishes.

随着地表相对高程的增加，水位变化幅度逐渐变小，在油桦－臌囊苔草群落中最小，这一方面可能与泥炭藓丘的分布有关，泥炭藓具有较强的饱水和持水能力，对水位的变化具有一定的缓冲作用；另一方面是由于该区靠近山地，山坡上形成的坡面径流可能对该区域有所补给，这也在一定程度上减小了水位的变化幅度。

A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。

Mount Muztag holds a near-round shape, is covered byperennial snow, with a snow line of about 5200 meters high. Northwest of the Mount is a glacial lake, Karakol, walled up by ancient moraines at a height of 3652 meters, with Chinese-Pakistani Road passing by its western side.

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.
