Abstract
A model of plant vegetation condition and physiological index in land surface process model was proposed in this papero At the same time the simulation of the process model (SPAM) in this paper was compared with bolli a land surface process model (LSPM) and the Monteith model. The results showed that the error of transpiration of plant vegetation calculated in LSPM was obvious, and the simulating value in the Monteith model was bigger. The simUlating results in SPAM was reasonable especially under the condition of water stress by introducing the suitable parameters of vegetation and plant physiological condition. This will be a base far deeply studying the interaction among vegetation, soil and atmosphere in the future.
