- Abstract
Based on the canopy temperature and micrometeorological data of Quercus variabilis in its main growth season (from May to August) in hilly areas of North China in 2011, this paper analyzed the variations of canopy temperature (Tc) in Q. variabilis plantation and their relations with micrometeorological factors in typically clear days and cloudy days. From 9:00 to 17:00 in clear days, the boundary layer of canopy was unstable, and the mean Tc was 3. 55 °C higher than the mean air temperature (Ta). In cloudy days, the variations of Tc were gentler than those in clear days. The Tc was significantly correlated with Ta, net solar radiation (Rn), relative humidity, and wind speed, with a multiple correlation coefficient being 0. 825. The Ta and Rn were the dominant meteorological factors controlling Tc, and their affecting degree on Tc was associated with weather condition.
