| 摘 要： | 为了更好地理解陆地表面水、热通量的空间差异，利用2009年和2010年1月黄土高原陆面过程观测试验（LOPEX）的陆面过程资料，对比分析了不同气候区主要地表水、热通量特征。结果表明：半干旱区的定西在近地层气象要素、土壤湿度、动量通量、地表能量及CO2通量等主要陆面特征物理量与半湿润区的平凉、庆阳差异明显;气候背景相接近的平凉、庆阳的主要陆面特征量比较接近。虽然地形、地势、海拔、下垫面影响因子也是影响陆面特征的重要因素，但是气候背景差异愈明显，陆面特征差异也愈大,即一个地区的气候背景是陆面过程特征的主要决定因子，对陆面特征产生综合影响，而地形、地貌只对一个或几个陆面物理量有影响。

| Abstract: | In order to have a better understanding of the spatial variation about the water and heat flux, based on the observation data of LOPEX(Experimental Study of Land Surface Processes in Chinese Loess Plateau), the mainly characteristics of water and heat fluxes in different climate region are analyzed. The results showed that the mainly land surface physical quantities in semi-arid region such as soil moisture, momentum flux, energy flux and CO2 flux are obvious different with that in semi-humid region. The characteristics of land surface fluxes in similar climate background region are similar. The factors of the terrain, elevation above sea level, underlying surface are important factors to water and heat flux, but the climatic background almost impact on all of the quantities of land surface fluxes, which is the decisive factor. |
