| Abstract: | A climatological model to estimate plant canopy temperature was developed on the basis of Monteith's energy balance equation of plant canopy. The follows were discussed: (1) the relations of the sensible heat, the latent heat and the net radiation fluxes of plant canopy to meteorological data, (2) seasonally amending the humidity function in the empirical formula of effective radiation in the net radiation under clear sky condition when used in China, (3) estimating the heat flux into or out of the plant soil continuum and its error's impact, and (4) according to climatological data of meteorological stations and biology physiology character's parameters, a model to calculate plant canopy temperature was given out from the iteration method of Newton Raphson, (5) the simulation results. |
