The AVS-SEM distribution in the sediments of Guanting Reservoir and Yongding River was studied and the metal concentration in the water above the sediments and the pore water was measured. Based on the results, the reaction between the sediments and metal ions were discussed and the heavy metal pollution of the sediments in Guanting Reservoir and Yongding River was evaluated preliminarily.

官厅水库沉积物，由于处于缺氧性环境，沉积物中的酸可挥发性硫化物控制着大多数金属离子在沉积物和孔隙水两相间的分配，本文通过现场采样，分析了官厅水库和永定河沉积物中的AVS—SEM的分布，同时测定了沉积物上覆水以及部分样点的孔隙水中的重金属浓度，探讨了沉积物与重金属离子的作用；并根据采样分析结果对官厅水库及永定河沉积物中的重金属污染做了初步评价。

Finally, we discuss the effect of water quality by fauna and food webs composition,and it is suggested to remove of the fish like Oreochromis sp and Cyprinus carpio carpio can further improve the water quality.

最后本文亦探讨水库中各种生物相所组成的食物链对於水库水质的影响，对於水库水质没有帮助反而易造成水质更加恶化的生物，像是吴郭鱼、鲤鱼，我们建议移除之。

In the qualitative and quantitative analyses, four kinds of methods such as cause analysis, vector statistics, fuzzy analysis and systematic cluster were synthesized and the applicability of them analyzed. Finally, in combination with the hydrometeorological characteristic of the north slope climatic zone of Tian Mountain and the operation of the reservoir, the flood season range are divided: 10 July 30 July flood season as main flood season and 1 August 15 August as later flood season. The result?

针对高山冰川作用下流域水库汛期分期的实际问题，以玛纳斯河流域夹河子水库为研究对象，识别汛期划分的主要影响因素，选择汛期划分依据，采用定性和定量分析相结合的方式，综合成因数理统计、矢量统计、模糊分析、系统聚类4种汛期分期方法，分析各种方法适用性，提取合理成分，结合天山北坡气候带的水文气象特征和水库控制运用特点，确定汛期范围：7月10日至7月30日为前汛期， 8月1日至8月15日为后汛期。

The phenomena of overproof of iron and manganese content in the reservoir water after heavy rainstorm in south areas is analyze d by taking one reservoir as a case based on studying the external pollution sources,groundwater,soil and sludge.

以福建省某水库为例，对南方地区暴雨后水库中铁锰超标现象从外污染源、地下水、土壤、底质多方面进行了分析，找出了该类型水库中铁、锰超标的原因，并提出建议。

It conducts thorough analysis on testing results of open sluicing of the reservoir during flood season in last three years and points out the fact that after scouring by a certain discharge, the reservoir will be difficult to be scoured even if bigger discharge comes.

对近三年来三门峡水库汛期敞泄排沙的试验结果进行了较为深入的分析，指出三门峡水库经过一定流量冲刷后，即令再来大流量也难以冲刷的事实，充分说明了水库冲刷与淤积并不是完全可逆的。

In order to calibrate the model, data of six typhoons such as the flood peak and the peak time are collected to compare with the result of the simulations. The result shows that the difference of the inflow hydrograph between them is very close. The average error of the flood peak is 5.21%. Furthermore, the error of the peak time is less than one hour but Wenny Typhoon is an exception by more than two hours. Therefore, the model could be applied to simulate the rainfall event at Shih-men watershed.

为验设模式模拟精确性，本研究以具代表性之六场台风降雨模拟，针对石门水库入流历线之观测流量与模拟值比较，结果显示模拟之水库入流历线与观测值差异不大，其尖峰流量误差绝对个平均为5.21%；另在预测洪峰到达时间方面，除温妮台风迟迟2小时外，其余均在1小时内，显示本分析模式可应用於石门水库上游集水区暴雨事件模拟。
