摘要：Over the past few centuries, global warming has become an indisputable fact, while many researches found that the potential evapotranspiration throughout the world showed a consistently decreasing over the past 50 years, and called this phenomenon as "evaporation paradox". In this study, we validated that it did exist in coastal wetlands of northern China and tried to understand the mechanism. The conclusions include: (i) The temperature of in coastal wetlands of northern China shows a significantly decreased trend while potential evapotranspiration is significantly increased, and suggests "evaporation paradox" actually exists in study area; (ii) The sensitivities of climate factors were that a 10% increase in T, T-max, T-min, RH, W and S would result in a 2.169% (increase 2.169%), 2.440%, 0.640%, -4.310% (decrease 4.310%), 1.413% and 4.416% in potential evapotranspiration (Eo), respectively; (iii) among the 6 climatic factors, the contribution rate of the effects on potential evapotranspiration were sunshine duration (41.65%) > wind (25.23%) > air temperature (18.04%) > relative humidity (12.51%). And the phenomenon of evaporation paradox in coastal wetlands of northern China was caused by the decrease of wind speed and sunshine duration.
