It is showed that the forest can not only increase net radiation but also decrease sensible and soilheat fluxes by decreasing surface reflectance and temperature.
这表明森林通过降低地表反射率和表面温度，不仅增加地表净辐射，而且减少其用于感热和土壤热通量的消耗。

The surface heat balance is discussed by involving the observational data of radiation and soilheat transfer, and the closed test of the surface heat balance equation is made.
The experiments identify that with the increasing of LAI , the ratio of soilheat flux to net radiation decreases from 0 13 in the jointing to 0 06 in the milking.
