中文摘要	结合对西北干旱区土壤盐渍化的影响因子研究,基于因子分析、物理量纲分析和Pi定理,建立了土壤盐渍化遥感信息模型.通过公式推导,得到了典型区域遥感信息模型的一般表达式,研究了多种因素组合对盐渍化形成和演化的作用.将模型应用于疏勒河流域双塔盆地,对该区域未来50 a的土壤盐渍化发展变化情况进行了预测.结果表明,双塔盆地土壤总体盐渍化面积基本不变,现状非盐渍土类型略有增加,同时轻盐土面积明显减少,特重盐土减弱为中、重盐土类型.土壤盐渍化遥感信息模型在一定程度上反映了区域盐渍化的情况,能够定量评价盐渍化的影响.
英文摘要	Combined with the researches on factors for the soil salinization in northwestern arid area of China, a remote sensing information model of soil salinization was established based on the physical factors analysis, the dimensional analysis and the Ⅱ theorem. The general expression of the remote sensing information model in typical study area was deduced. The influences of combination of various factors on the formation and development of soil salinization were studied. The model was applied in Shuangta Basin in Shule River watershed, and the trend of soil salinization in this area in future 50 years was predicted. The results show that the total area of salinized soil in Shuangta Basin almost have little change, the non-salinization soil has a slight increase, the lightly-salinized soil obviously decreases and the extremely-salinized soil changes to the mid-salinized soil or heavily-salinized soil. The remote sensing information model can reflect the regional situation of soil salinization to some extent and can be employed to quantitatively evaluate the influences of soil salinization.
