摘　　要：冉庄实验站在种植小麦、玉米情况下坚持实测土壤含水量,积累了大量实验资料,据此,对表层土壤水消退的时空变化规律进行了全面分析,揭示了土壤水由湿变干的完整变化过程以及消退系数K值的变化规律。The soil moisture and the capacity have been observed and a lot of experimental data has been accumulated in Ranzhuang experimental station in the conditions of growing wheat and corn.Hereby,the spatio-temporal transformation of the subsidizing orderliness of the soil moisture has been analyzed.It opens out a movement process of the soil moisture from wet to dry and the variation orderliness of K value-- - the subsidence coefficient.

关 键 词：土壤水 消退系数 时空变化 土壤含水量 降水 水面蒸发量
