The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

After operating the method of storing clear water and discharging muddy water in Sanmenxia Reservoir, the main reason for erosion and deposit in riverway is the change of running water level in flood season .

三门峡水库蓄清排浑运行以来，决定潼关以下库区河道冲淤主要是水库运行水位的高低，汛期水库运行水位的高低对潼关高程的升降起着主要的作用，因此汛期潼关高程的变化主要由水库运行水位决定的。

At the same time of changing watershed intrinsic natural relation, people destroyed its crude system. Watershed is faced with more and more serious crisis in water environment and water lack, which result in water quality worsened, more sandiness, reservoir silted.

人类改变流域原有的自然联系的同时，也破坏了流域天然系统，使流域面临着愈演愈烈的水生态环境危机和严重的水资源短缺问题，从而导致流域上游水质恶化，河流含沙量加大，中下游水库淤积严重。

According to the new comprehension of ecological theory and sustainable development, several suggestions, aimed at developing economic and protecting ecosystem, are put forward, such as designing fine ecological structure, installing the monitoring points in the reservoir to get changing data of water, developing taintless industries to protect water with water, playing government role in the ecological protection and so on.
