    摘要:

    基于土壤水分運(yùn)動(dòng)的動(dòng)力學(xué)方程,，建立了蓄水坑灌單坑土壤水分運(yùn)動(dòng)的數(shù)學(xué)模型及邊界條件，利用有限體積法對(duì)模型進(jìn)行了求解。為了驗(yàn)證所建模型的準(zhǔn)確性,，在室內(nèi)進(jìn)行了蓄水單坑水分入滲試驗(yàn),。模擬結(jié)果和試驗(yàn)結(jié)果的對(duì)比表明,，土壤濕潤(rùn)鋒和含水率的模擬值與實(shí)測(cè)值吻合較好,，說(shuō)明所建立的蓄水單坑二維土壤水分運(yùn)動(dòng)模型是正確的,，采用有限體積法求解是可行的。該模型可作為預(yù)測(cè)蓄水坑灌條件下單坑土壤水分運(yùn)動(dòng)的有效工具,。

    Abstract:

    Based on the theory of soil water dynamic, a simulating model and boundary conditions for the soil water of water storage single pit irrigation were established, and the model was numerically solved by finite volume method. The results showed that good agreement was obtained between simulated and measured wetting front and soil moisture content. It indicated that the mathematic model was correct and the model solving with finite volume method was feasible. It is concluded that the model could be used to implement water transport in soil under the water storage single pit. 
