干旱区平原水库防蒸发节水试验初探

Preliminary Experimental Study on Water Saving by Preventing Evaporation in Arid Area Plain Reservoirs

针对干旱区平原水库面积大、水深浅,无效蒸发损失严重这一特点,提出用聚苯乙烯泡沫塑料板覆盖部分库区水面以减少无效蒸发损失量,从而提高水库的有效利用率。以尉犁县塔里木二库为试验对象现场试验,初步探讨干旱区平原水库防蒸发节水的工程措施。

Based on large area,shallow water and a large amount of ineffective evaporation of plain resourvoirs in arid area,the authors put forward a suggestion that polystyrene foam plastics slabs shonld be floated on the surface to improve effective utilization of the resourvoirs.In this paper, the spot experiment is done in the No.2 Tarim reservoir of Yuli County. In order to prevent evaporation in arid area plain reservoirs, the engineering measure of saving water is preliminarily discussed.
