根据宁夏银北灌区5次土壤盐渍化调查结果，总结得出其土壤盐化程度主要经历了增长、明显减缓、增长3个历史时段和两个转折点，并对不同阶段土壤盐渍化的主要特征及成因进行分析。在此基础上总结得出宁夏银北灌区土壤盐化以轻度、中度盐化为主，呈紧邻黄河，多临排水渠，以湖泊、洼地周围见多的空间分布特征。根据土壤盐化时空分布特征，提出盐渍化分区治理重点及相应治理措施，建议以科技创新推动治理技术集成应用，建立技术集成平台，发展盐渍化治理新模式，来治理银北灌区盐渍化问题。

According to the 5 investigation results of soil salinization in northern Yinchuan plain of Ningxia,the soil salinization mainly experienced three historical periods and two turning points of growth,significant reduction and growth. The characteristics of each period were analyzed. The saline regions were mainly close to the Yellow River,near drainage canals and around lakes. The most of them were mild and moderate salinization. Accord-ing to the characteristics of spatial distribution and temporal changes,the corresponding control measures of each saline region were put forward in this paper. It suggested that the control of salinization should be based on the integrated application of technologies. A technical integration platform should be established to create a new governance model of salinization to solve the salinization problem in northern Yinchuan plain of Ningxia.
