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.

Key words:  Loess Plateau      water and heat characteristics      surface flux      semi-arid/semi-humid region
