Abstract: The principles of limiting factors are analysed and reviewed, and on this basis, the dynamic model of plant production is designed and simulated which can better reflect the effects of climate(temperature, water, light etc.), basic ground(physical geography, soil), investment and their interactions on plant production. The model has been applied to the prediction of wheat yields in the west district of the Yellow River in Gansu province and satisfactory results are obtained.
