摘要: 根据器测法确定水面蒸发量,其精度决定于观测本身的精度与折算系数的正确性。折算系数与气象要素之间关系密切,有月间变化,但年际变化较小。通过蒸发池与各型蒸发器的对比观测确定我国不同气候区,各型水面蒸发器的折算系数。

Abstract: Evaporation data of nineteen evaporation experimental stations to be located in different climatic regions in China have been calculated and analysed, and pan coefficients of evaporation pans of water of four types (E601, ΓΓИ—3000, Φ80cm., Φ20cm.,)for different months and the average of years have been determined. The result shows that average annual pan coefficients for various pans and for various climatic regions are difference. The average annual pan coefficients of E601, ΓΓИ—3000, Φ80cm., Φ20cm. are 0.93, 0.88, 0.77 and 0.62 respectively. These coefficients for humid regions are slightly greater than above values and for arid regions are slightly smaller than above values. An experimental relation between average pan coefficients of the pan of E601 type and average relative humidities has been obtained, this may be for the unstudied region reference.
