| 摘 要： | Based on observation data from the mini-type automatic weather station,the evapotranspiration quantity of reference crops from artificial grassland in three river sources areas was estimated by the method of FAO Penman-Monteith.The actual evapotranspiration quantity of grassland was calculated according to the synthetic crop coefficients referenced by FAQ-56,and the change of the actual evapotranspiration quantity of artificial grassland in three river sources areas as well as the relationship between the evapotranspiration quantity and climatic factors were studied.The results suggested that the seasonal change of actual evapotranspiration quantity in grassland was expressed in a single peak curve with the peak in the middle August,and daily transpiration quantity in summer was significantly larger than that in winter.The evapotranspiration was significantly correlated with air temperature,solar radiation and relative humidity,but not significantly correlated with wind speed.Effects of climatic factors on the evapotranspiration quantity of artificial grassland were ordered as follow:air temperature(T)>solar radiation(Ra)>relative humidity(RH)>wind speed(u2).

| Abstract: | Based on observation data from the mini-type automatic weather station, the evapotranspiration quantity of reference crops from artificial grass-land in three fiver sources areas was estimated by the method of FAO Penman-Monteith. The actual evapotranspiration quantity of grassland was calculated according to the synthetic crop coefficients referenced by FAQ-56, and the change of the actual evapotranspiration quantity of artificial grassland in throe river sources areas as well as the relationship between the evapotranspiration quantity and climatic factors were studied. The results suggested that the sea-sonal change of actual evapotranspiration quantity in grassland was expressed in a single peak curve with the peak in the middle August, and daily transpi-ration quantity in summer was significantly larger than that in winter. The evapotranspiration was significantly correlated with air temperature, solar radia-tion and relative humidity, but not significantly correlated with wind speed. Effects of climatic factors on the evapotranspiration quantity of artificial grass-land were ordered as follow: air temperature (T) > solar radiation (Ra) > relative humidity (RH) > wind speed (u2). |
