It is very important for winter wheat irrigation decisionmaking to monitor the regional soil moisture in Hebei Province because it is relatively dry during the development stage of winter wheat.Based on the Verdatile Soil Moisture Budget(VSMB) model for winter wheat at a single station,parameter modification is made according to the soil types and the developing stages of winter wheat from south to north in Hebei Province,and the Regional Soil Moisture Monitoring and Forecasting System(RSM-MFS) model for winter wheat in Hebei Province is established.The essential principles and functions of the system are described,and the effectiveness of application is analyzed.The results indicate that the relative monitoring error is about 10%,and the relative risk forecasting error is about 20%.
