摘要： 本文根据黄淮海地区１９９３～１９９５年麦季实测土壤水分、农业气象资料和卫星监测资料,试验了区域性土壤水分模型,以便模拟区内土壤水分及其相关要素的动态变化过程,解决以往土壤水分遥感模型只确定土壤水分含量不能确定水量结构的缺点。试验取得比较满意的效果,成功地利用遥感数据作为模型的输入,达到土壤墒情监测、水文水利分析和农作物遥感估产的目的。模型在输出水量结构的同时还提供了人类活动对水环境影响的信息。

Abstract: According to the measured soil moisture,the agricultural meteologic data and the satellite monitoring data of the wheat season of the North China Plain in the years1993—1995,a regional soil moisture model is tested to simulate the process of the dynamic change of soil moisture and its related elements and to overcome the defect that former remote sensing model of soil moisture can only determine the soil moisture content but not the structure of water amount. This test has gained satisfactory effects. It successfully uses the remote sensing data as the input of the model and reaches the goals of monitoring the soil moisture conditions,analysing the hydrology and water conservancy and estimating the crop production based on remote sensing. At the time of exporting the structure of water amount,the model can also provide the information about the impacts of human activity on the water environment.

Key words: soil moisture, monitoring, water circulation, simulation model
