| Abstract: | Based on the evaporation capacity data of Shangqiu weather station from 1961 to 2000, the variation tendency and impact factors of the evaporation capacity were analyzed. The results showed the annual, seasonal and monthly evaporation capacity variation had the obvious downtrend in recent 40 years. The main impact factors were the wind speed, the sunlight radiation, the relative humidity and the water vapor pressure. |
