| 摘 要： | 田间土壤水变化的概念性模型包括根区土体水量平衡、根区下界面水分通量和作物蒸发蒸腾量等模型。根据山西临汾灌溉试验站2009年与2010年冬小麦试验资料,采用田间试验与理论分析相结合的方法,利用作物蒸发蒸腾模型、根区下界面水分通量模型进行了麦田土壤水分动态模拟。结果表明:田间土壤水分变化概念性模型计算的麦田土壤储水量与实测值有较好的一致性,模拟计算值和实测值的相关系数为0.958 7,拟合精度和预测精度均较高,相对误差为4%～12%。

| Abstract: | Conceptual model of soil moisture changes includes the balance equation of soil water in root zone,the water flux under the interface of root zone and the model of cropevapotranspiration.We used the data of winter wheat between 2009 and 2010 from Irrigation Experiment Station in Linfen of Shanxi,adopted analytical way combining theoretic analysis with field trial,simulated soil moisture dynamics in the wheat field through the model of the water flux under the interface of root zone and crop evapotranspirati... |
