摘要

There is a complex nonlinear relation between soil moisture and precipitation,irrigation, evapotranspiration, root zone lower bounds, etc. It causes the changing rule of soilmoisture very complex. Based on analyses of artificial neural network theories, this paper setup a BP model that describes soil moisture change of limited irrigation rice zone. Thepackets in the soil water forecast are compared with the packets in the observations.Research indicates the BP network can be used in the regional soil moisture forecast. Themethod has the characteristics of simplicity, feasibility and high accuracy.
