摘要: Abstract Evaporation, influenced by water and energy conditions, reflected the combined effects of climate, vegetation soil in different basins. Trend analyses pan evaporation were conducted on 298 stations significant trends also explored Kendall τ Linear fitted model method during 1959-2000 China. The causes for changes discussed basins results presented that decreasing detected most China, which ranged from -0.02 to -30.48 mm a-2. spatial distribution negative mid-latitude regions followed basin south region, Northeast region southwest region. evaporation, changed China generally sunshine hours maximum air temperature important meteorological variables influence relative humidity, wind speed, average minimum whole country.
