Abstract By making use of integrated data of a variety of land surface physical parameters observed in Dingxi Synthetical Experimental Observatory of Land Surface Process in the Loess Plateau from November, 2004 to October, 2005, annual and daily variations characteristics of soil temperature, precipitation, land surface albedo, surface radiation components and energy balance components in the semi-arid region are systematically analyzed, as well as their influencing mechanism. Results show that the characteristics of land surface process over the Loess Plateau are different from in other regions. Downward transfer velocity of soil temperature is about 2.5~3.5 h/10cm. The land surface albedo decreases with soil moisture increasing, and their correlation coefficient is 0.5338; the land surface albedo increases with snowfall increasing, and the correlation coefficient is 0.6645. The maximum value of long-wave radiation appears later about 1 month than the total radiation. It takes one hour for solar radiation to heat the land surface and atmosphere. Latent heat flux in summer is five times more than in winter. There are two obvious peak values for sensible heat flux. The daily peak values of latent heat flux, sensible heat flux, and soil heat flux lag 30 minutes or long to one hour behind the net radiation.
