黄河三角洲及渤海莱州湾滨海区土壤资源以土壤含盐量高和肥力低为其突出特点。干旱的气候、黄河尾阎河道的摆动、咸水的侵染、风暴潮的侵袭等自然条件和人类活动决定着土壤发生与发展的总趋势。生物与工程措施相结合综合洽理早、涝、盐、咸、瘦，农、林、牧、渔、盐综合发展，是合理开发利用土壤资源、维护生态平衡的可行途径。 Soil resources in the Yellow River Delta and Laizhou Bay coastal areas of the Bohai Sea are characterized by high salinity and low fertility. The general trend of soil occurrence and development is determined by the natural conditions and human activities such as the arid climate, the swing of the Yellow River, the flood of salt water, the storm surge and so on. Comprehensive combination of biological and engineering measures Comprehensive development of early, waterlogging, salt, salt, lean, agriculture, forestry, animal husbandry, fishery and salt is a feasible way to rationally develop and utilize soil resources and maintain ecological balance.
