干旱区平原水库防蒸发技术研究现状及展望

Current Situation of Research and Expectation of Preventing Evaporation Technology in Plain Reservoir

西北干旱地区可利用水资源严重缺乏是制约地区经济发展的重要原因。干旱区平原水库水量蒸发损失十分严重,防蒸发技术是一种应用在平原水库上的高效节水技术。在介绍国内外防蒸发技术研究现状的基础上,提出了今后防蒸发技术的研究发展方向:(1)防蒸发装置最佳的设计方案;(2)准确计算水面蒸发量的方法;(3)防蒸发技术与光伏发电技术相结合的系统;(4)防蒸发技术的应用标准和技术规范等相关准则的制定。

It is an important factor that restricting the development of regional economy in arid areas of the northwest of China is severe shortage of available water resources. The water loss of evaporation in plain reservoir is very serious,so the anti-evaporation technology that applied to plain reservoir is high efficiency for water-saving. On the basis of introducing the research status of anti-evaporation technology at home and abroad,this paper put forward the research and development direction of anti-evaporation technology in the future： a） the optimum design of anti-evaporation device; b） the method of accurately calculating the evaporation capacity of water surface; c ） the system that com-bines anti-evaporation technology with photovoltaic power generation technology and; d） the formulation of standards and technical specifica-tions for the application of anti-evaporation technology.
