摘要：基于2011年栓皮栎主要生长季(5—8月)的冠层温度数据及同步观测得到的冠层微气象资料,分析了典型晴天和阴天条件下华北低丘山地栓皮栎人工林冠层温度(Tc)的变化特征及其与微气象因子的关系.结果表明:晴天日9:00—16:00,栓皮栎人工林林冠边界层处于不稳定状态,Tc比空气温度(Ta)平均高3.55℃;阴天日Tc的变化较晴天条件下平缓;Tc与Ta、净辐射(Rn)、相对湿度、风速等冠层微气象要素的复相关达极显著水平,其复相关系数为0.825;影响Tc的主要气象因子是Ta和Rn,二者对Tc的影响程度与天气状况有关.
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 ℃ 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.
