| 摘 要： | 通过对地下水盐均衡和包气带的盐通量及积盐率计算，用土壤盐碱化预报模型，对吉林西部洮儿河流域不同地貌单元进行了土壤盐碱化预报研究，流域内土壤盐碱化发展的总体趋势加重，但不同地貌单元的发育程度有很大的差别，从流域的上游到下游，土壤盐碱化人无到有，由轻到重。传统上用发展速率的方法预测盐碱化是不严谨的。

| Abstract: | The balance of salt in the groundw after and salt flux and rate of salt accumulation in vadose and forecasted soil salinization of different landforms in Taoer river basin of Jilin province is calculated with soil salinization forecast model. The generalt rend of soil salinizaton will be aggravated in the river basin, but there is much difference in diverse landforms. Soil salinization become more aggravating from the upper reach to the lower of the river basin. The traditional method of forecasting soil salinization with developing rate is not precise. |

| Keywords: | salinization forecasting salt balance in groundwater vadose salt flux salt accumulation rate |
