水库湖泊水面蒸发的分析计算

Analysis and calculation of free water surface evaporation from reservoir and lake

水库、湖泊水面蒸发量不能直接观测，需用一些方法计算，有器测法、水量平衡法及由能量平衡和动力学方法得到的经验模型法。

Water surface evaporation capacity of reservoir or lake can 't be directly observed and should be computed with such methods as instrument-measurement method , water balance method , as well as experience model set up from energy balance and dynamics method .

城市景观湖泊中漂在水面上的浮泥不仅影响水体景观，而且还阻碍空气中的氧向水中传输，影响水质。

The floating sludge over landscaping lake in city not only affects water sight , but blocks oxygen transferring from air to water .

在人类活动的强度干扰下，湖泊数量锐减、水面萎缩、被不同程度地污染已经成为城市湖泊演变的普遍现象，严重影响了湖泊的生态服务功能。

Unfortunately , there exist quite universal problems that the number of urban lakes reduced , area of lakes shrinks , and lakes are polluted in different degrees under the historical and present intensive interference of human activities , which limit seriously the ecological service function of urban lakes .
