中文摘要:

为进一步探究采用物理覆盖对干旱区平原水库静水水面蒸发的影响程度，本试验选用直径为100 mm黑色PE浮球作为覆盖材料，选用两个面积均为1 m²的正方形铁皮箱作为蒸发器（A蒸发器、B蒸发器）。A蒸发器内水面用浮球全覆盖（覆盖率为86%）、B蒸发器内水面不覆盖。通过A、B两蒸发器对比试验得出：浮球对蒸发器内水面平均蒸发抑制率为83.8%。在干旱区平原水库等大水体中大面积覆盖浮球时（覆盖率接近91%），浮球对其静水水面蒸发抑制率为89.6%。

英文摘要:

In order to further explore the influence of physical coverage on still water evaporation from water surface in arid zone plain reservoir, the experiment selected the black PE floating balls with a diameter of 100 mm as the cover material, and two 1m² area of the square tin trunk were selected as evaporator (A evaporator and B evaporator). The A evaporator is completely covered with floating balls from the water surface (the coverage rate is 86%), and B is not covered. Through the comparison test of A and B evaporators, the inhibition rate of the floating balls to the water surface of the evaporator is 83.8%. When the arid zone plain reservoir were largely covered by the floating balls (the coverage rate is close to 91%), the inhibition rate of the floating balls to the surface of the water can reach 89.6%.
