Abstract: Deal with the processes which soil moisture and evapotranspiration affect the forage grass production, in order to a numerical model is developed for simulating the dry weight of the pasture increasing.Numerical simulation is carried out according to meteorological elements of high cold meadow in the northern part of Qinghai province, and the numerical results turn out in good agreement with the experimental data.The model is of practice value for predicting forage grass production in high cold meadow region.

Key words: High cold meadow, Yield model, Numerical simulation

摘要： 本文讨论了土壤含水量和蒸散量对牧草生长量的影响过程,提出牧草干物质增长模式,并根据青海海北高寒草甸地区的气象条件,对牧草生长量模式进行数值模拟,同时,与实测值进行比较,模拟结果与实测值趋向一致,可为牧草产草量预报提供一定实用价值和科学依据。
