In this paper,dynamic changes of lacustrine water in the Sihu area were analyzed by using remote sensing.

采用遥感方法分析了四湖地区的湖泊水域的动态变化，分析结果表明：该地区 50年代至 80年代初由于大规模围湖造田，致使湖泊水域萎缩相当严重，80年代以后，湖泊水面急剧减少的趋势得到遏制，而 90年代以后，湖泊水面基本处于无显著变化状态。

The objective of research is to analyze the advantage and disadvantage of training environment in the Sun Moon Lake and Dong-Shan River rowing training center. The achievements of research are as the followings: 1. The weather condition: a. The area of Dong-Shan River is easy affected by seasonally northeaster and the influence of seawater tides that increase resistance for contestants when training. Nevertheless, the area of Sun Moon Lake doesn't affect at all.

本研究旨分析日月潭和冬山河水上划船训练中心训练环境的优劣，针对气候、潮汐、温度、雨量、水质等进行分析，所得的研究结果如下：一、气候方面：冬山河水域易受到东北季风及海水潮汐的影响，增加选手在训练时的阻力；日月潭水域并无此影响。

Wide oceans contain abundant resources. With increasing worldwide demand for oil and gas, exploitation of ocean oil and gas switch to deep water and ultra-deep water fields with water depth of 450~1500 meters and more than 1500 meters respectively.

辽阔的海洋蕴藏着丰富的资源，随着世界油气需求的增加，海底油气的开采向水深450~1500米的深水域和水深1500米以上的超深水域发展。

Wetland refers to natural or artificial, permanent or temporary marshes, peat bog and waters (motionless or flowing, fresh water or salt water) including coastal seawater areas no deep than 6m in low tide.

湿地指天然或人工，长久或暂时性的沼泽地，泥炭地或水域地带和水域（一动不动或流动，淡水或海水）包括沿海海水地区没有超过6米深低潮。

在坚持大水域人工投放粗养的同时，大小水域并举，发展了库湾养鱼，围拦养鱼，流

The principal point of this research is to understand the managerial items of ecological engineering of the river ecological engineering through the proprietor's a point of view.

本研究主要针对河川水域生态工程，以管者角探究河川水域生态工程生命周期由规划、设计、施工至维护等阶段之管项目。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. 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。
