用对流弥散方程确定脱盐系数

Determination of desalinization index by convective diffuse model

应用土壤溶质运移的对流弥散模型,提出确定脱盐系数的新方法。应用本文提出的方法,计算了秦王川灌区不同土壤类型的冲洗定额,对于治理秦王川灌区盐渍地有现实意义。

A new method for determinig desalinization index was provided by convective diffuse model of soil solute motion. The physical concept is clear, the need index is fewer and the calculated result is reasonable. It is a better methed to determine desalinization index. Using the method in this paper, washing quota of different soil type in Qing Wang Chuan irrigated area was calculated, which had realistic significance for harness salinized soil there.
