摘　　要：对江苏连云港赣榆沙质海岸土壤理化性质,即土壤质地、体积质量、孔隙度以及有机质、全氮、全磷、速效氮、磷和含盐量、pH进行了分析研究。结果表明,该沙质海岸土壤偏碱性,土壤孔隙度平均值为36.21%,含盐量在0.19%～0.41%之间,属于中度盐渍化土,有机质含量为4.5～18.6 g/kg、全氮0.17～1 g/kg、全磷0.26～0.45 g/kg,各项指标含量普遍偏低。研究结果将对沙质海岸防护林体系建设提供科学依据和技术支撑。The soil physical and chemical properties, including soil bulk density, soil porosity, soil texture, organic matter, pH, total nitrogen, total phosphorus, available nitrogen, phosphorus and salt content, in the shelter-forests in the sandy coastal areas were investigated in Ganyu County, Jiangsu Province. The results showed that the soil in the sandy coast was alkaline. The average soil porosity was 36.21%. The salt content in soils was between 0.19 % and 0.41%, which was moderate salinization. The content of soil organic matter, the total nitrogen and the total phosphorus was 4.5-18.6 g/kg, 0.17-1.00 g/kg and 0.26-0.45 g/kg, respectively. The results would play an important role in the species choice for the sandy coastal protection forest.
