Abstract:

Abstract:This paper analyzed the evapotranspiration and related Influential meteorological factors data of Vantage pro2 mini automatic meteorological station of Aksu zone in Xinjiang, it analyzed the impact of each meteorological factor to the evapotranspiration by the grey relational grade analysis method，the results indicated the arrangement of impact extent from strong to weak was the Energy of Solar Radiation,Average temperature, Highest temperature,Lowest temperature,Average wind speed, Average relative humidity.From these results,in the facility agriculture field，we can reduce the crop water requirement indirectly by controlling the main influential meteorological factors of evapotranspiration in order to achieve the goal of saving the water resources.
