摘要：

滨海土壤盐渍化问题是海岸带区域典型灾害之一，近30年来海水入侵加剧了灾害的发展。为了研究海水入侵对土壤盐渍化的影响过程和程度，选取莱州湾南岸昌邑市北部滨海区域为研究对象，通过对地下水和土壤样品的采集、整理和化学分析，通过Excel和SPSS相关模块的相关性分析和聚类分析，研究微地貌、海水入侵、土地利用方式等9个主要影响因子对滨海土壤盐渍化的影响过程，并对各因素进行聚类分析。结果表明，地下水矿化度（TDS）与土壤全盐量相关系数达0.87，海水入侵与土壤盐渍化具有典型相关关系；海水入侵是引起滨海土壤盐渍化的主要因素；最后，遵循生态保护和可持续发展的策略，提出了3方面的防治盐渍化生态修复措施。

Abstract:

Coastal soil salinization problem is one of the typical disasters in coastal regions, where seawater intrusion has exacerbated disasters in the past 30 years of development. In order to study the effects of seawater invasion on soil salinization process and extent, the northern coastal region of Changyi City had been chosen to be studied on the soil salinization as the typical seawater intrusion area in Laizhou Bay. Firstly, groundwater and soil samples had been collected and analyzed. Then, the influence processing of micro relief, seawater intrusion and land use to the soil salinization had been studied. The results showed that correlation coefficient between TDS and soil salt content was 0.87, seawater intrusion and soil salinization had the typical relationship. Seawater intrusion was the main factor that influenced the soil salinization in coastal region. At last, three ecological restoration measures had been proposed to control soil salinization.
