摘要
黄河是一条多泥沙河流。以往在计算黄河河道和水库水面蒸发时,都是根据陆地蒸发器观测的清水静水水面蒸发来计算的,这样计算是否会产生较大的误差,一直是大家关心的问题,目前有关动水水面蒸发的研究还很少。我们于1995年7—10月在巴彦高勒蒸发实验站进行了清水、浑水动水蒸发实验。本次实验结果表明,清水、浑水动水水面蒸发均比清水静水水面蒸发量大,这一结论对准确计算河道水面蒸发和水库水面蒸发及水资源研究等方面具有重要的意义。
The Yellow River is a sediment loaded river.The calculation of water surface evaporation in the channel and reserviors in the past are according to the observation and measurement of clear and static water in evaporation pan over ground, and what is concerned about the calculation is if it leads to some big error. Up to now there are still little study on moving water evaporation. The experiments of clear and sedi-ment-loaded moving water evaporation had been conducted in Bayangaole Evaporation Experimental Station from July to October of 1995. The results show that the evaporation of clear and sediment-loaded moving water is larger than that of static water. The conclusion is of great importance to accurate calculation of evaporation in channels and reserviors, to water resource study, and so on.
