采用聚苯乙烯板、浮球覆盖水面，研究两种覆盖水面条件下的水面防蒸发效果。研究结果表明：旱区水库采用覆盖水面来抑制水面蒸发是可行的；水面蒸发抑制率与水面覆盖率不成正比；水面覆盖聚苯乙烯板后的水面覆盖率为81%，平均水面蒸发抑制率为49.4%；水面覆盖浮球后的水面覆盖率为约为90.8%，平均水面蒸发抑制率为61.2%；相同条件下采用浮球覆盖水面抑制水面蒸发效果较好。
採用聚苯乙烯闆、浮毬覆蓋水麵，研究兩種覆蓋水麵條件下的水麵防蒸髮效果。研究結果錶明：旱區水庫採用覆蓋水麵來抑製水麵蒸髮是可行的；水麵蒸髮抑製率與水麵覆蓋率不成正比；水麵覆蓋聚苯乙烯闆後的水麵覆蓋率為81%，平均水麵蒸髮抑製率為49.4%；水麵覆蓋浮毬後的水麵覆蓋率為約為90.8%，平均水麵蒸髮抑製率為61.2%；相同條件下採用浮毬覆蓋水麵抑製水麵蒸髮效果較好。

This paper studies the anti-evaporation efects of the two schemes:using polystyrene plates and floating bals cover the water surface.The results show that:using the method of covering the water surface to suppres evaporation is feasibil for arid regions reservoir;anti-evaporation rate is not proportional to the wate surface coverage rate;when using polystyrene plates cover the water surface,the coverage rate is 81% and the average anti-evaporation rate is 49.4%;when using floating bals cover the water surface,the coverage rate is 90.8% and the average anti-evaporation rate is 61.2%;the efect of using floating bals cover the water surface to supres evaporation is beter under the same conditions.
