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.
