| 摘 要： | 文章根据多年实际观测资料，在土壤水分平衡参数模拟方法的基础上，利用初始土壤有效水分贮存量、降水量和实际蒸散量3要素，建立了0～50 cm土层的土壤水分动态监测模式，确定了各项参数的计算方法。通过11个站点两年的检验和试用，对主要农作物春小麦和春玉米农田的水分状况监测准确率达80%以上。同时，对两个站点的土壤水分进行了预报，准确率平均为92%。

| Abstract: | Based on the simulation of soil water balance parameters, a dynamic model was developed to monitor soil moisture content in 0–50 cm soil layer using the observational data for many years. The model uses effective moisture storage of initial soil, precipitation and actual evapotranspiration as basic elements to determine the parameters of the model. Through the test and application of the model in 11 stations, the monitoring accuracy of moisture condition for spring wheat and corn was higher than 80%, and the mean forecast accuracy of soil moisture in 2 stations was 92%. |
