长白山阔叶红松林显热和潜热通量测算的对比研究

COMPARISON OF THE MEASUREMENT AND ESTIMATE OF SENSIBLE AND LATENT FLUXES OVER BROADLEAVED KOREAN PINE FOREST IN CHANGBAI MOUNTAIN

为了探寻近地面层湍流运动规律 ,定量分析森林下垫面物质与能量垂直输送 ,本文利用常规气象梯度和开路涡动相关观测系统的数据 ,应用涡动相关法和空气动力学法对长白山阔叶红松林的显热和潜热通量进行了测算 ,并对两种方法得到的结果进行了对比。结果表明 ,两种方法得到的显热和潜热通量结果相差不大 ,而且随时间变化的曲线形状也极其相似。而且 ,二者得到结果的线性相关性显著。

In order to find out the rule of turbulence and to quantificationally analyze the vertical transport of energy and material over forest, the sensible heat flux and latent heat flux over broadleafed Korean Pine forest on Changbai Mountain are calculated, using the data measured by the Routine Meteorological Measurement System and Open-Path Eddy Covariance Measurement System, based on the eddy covariance and aerodynamic methods. Then the results mentioned above are compared.The results measured by these methods are very close in quantity and the change with time, and their linear correlations are significant.
