Abstract: During May to July in 2013,environmental factors were observed in real-time including air temperature,air relative humidity,total radiation,net radiation,soil water content,wind speed on the lawn,and the canopy-air temperature difference of the tall fescue lawn conditions was calculated in continuous-time period.This paper studied the diurnal variation of canopy-air temperature difference under different irrigation and weather conditions and analyzed their data characteristics of environmental impact.The correlation equation between Tc-Ta and environmental factors show that canopy-air temperature difference has a good relationship with RHand VPD,which can reflect soil water status well and provide theoretical basis for the soil water content of the lawn’s diagnosis.
