| Abstract: | 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. |
| Keywords: | desalinization index convective diffuse model saline harness |
