土壤墒情实时监测是开展作物实时灌溉预报的重要前提，而根区土壤含水率精确数值的获取对提高实时灌溉预报的精度具有重要意义。采用层次分析和变异系数法组合赋权的方法计算了冬小麦计划湿润层内各土层土壤含水率的权重，并应用在郑州地区不同水分处理的冬小麦实时灌溉模型中。结果表明：组合赋权计算的日土壤含水率和灌水总量更符合试验区冬小麦自身生长规律和节水灌溉要求。通过组合赋权计算的日土壤含水率具有较高的准确性，可为冬小麦实时灌溉预报提供良好的基础数据支持。

Soil moisture real-time monitoring is the important component of the real-time irrigation forecasting,and the precise values of root zone soil moisture have important significance of improving the precision of real-time irrigation forecasting. This paper used hierarchical analysis and coefficient of variation of empowerment method to calculate the wet winter wheat plan the weight of each soil layer in the layer of soil moisture content,and the weight was applied in different water treatment in Zhengzhou area in the real-time irrigation model of winter wheat. The results show that using this combination of empowerment,the soil moisture content and water conforms to the experimental zone law of winter wheat growth and water saving irrigation requirements. Therefore,the combination of empowerment calculation makes the soil moisture content have high accuracy,and it can provide foundation data support for winter wheat real-time irrigation forecasting.
