摘　　要：通过对相思树种更新木麻黄防护林对沿海沙地土壤化学性质的分析,结果表明:与木麻黄林分相比,在沿海沙地后沿应用相思树种造林使沙地土壤中水溶性C l-和Na+含量降低,而使表层土壤中的水溶性Ca2+含量升高;相思树种能明显地改善沙地土壤中有效养分的供给,然而,对不同的相思树种来说,其改善程度有所差异;相思树种明显地增加了沿海沙地土壤中全氮和全碳的含量,且增加的量以沙地土壤的表层最为显著。Through the analysis of the effect of Casuarina equisetifolia protection forest regeneratd by Acacia tree species on chemical properties of soil , the results showed that compared with stand of Casuarina equisetifolia the water-soluble Cl^- and Na^＋ in sandy land were reduced by using Acacia tree species, the content of the water-soluble Ca^2＋ in topsoil was increased. Acacia tree species could improve significantly the supplying of available nutrient in the soil of sandy land . The improving degree had differences to different Acacia tree species. Acacia tree species increased significantly the content of total N and total C and the increment of topsoil of sandy land was significant.
