抑制干旱区平原水库无效蒸发技术分析

Analysis of Inhibiting Ineffective Evaporation of Plain Reservoirs in Arid Areas

针对西北干旱区水资源短缺限制社会经济可持续发展问题,分析了现有防蒸发技术研究现状,提出在对输水和用水过程节水控制的同时,还需加强对源头节水控制,降低平原水库无效蒸发是该地区节水技术发展的主要研究方向,主要通过化学试剂覆盖法、种植水生植物法、固体漂浮物覆盖法抑制水面无效蒸发,减少水分损失,为后续试验研究提供参考。

Aiming at the problem of water resources shortage in the arid area of Northwest China and restricting the sustainable development of society and economy,the current research status of anti-evaporation technology is analyzed,and it proposes that while controlling the water delivery and water saving process,it is necessary to strengthen the control of the source water saving.Reservoir invalid evaporation is the main research direction for the development of water-saving technology in this area.It mainly uses chemical reagent covering method,planting aquatic plant method,and solid floating object covering method to suppress ineffective evaporation on the water surface and reduce water loss,which provide reference for subsequent experimental research.
