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.
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。

Being short of coastal sandy land forestation species, bad system stability, faint resistance, seriousplant diseases, we proposed to cultivate Acacia tree species which had extensive adaptability and strongresistance to typhoon and arid site.
针对沿海沙地上造林树种缺乏，原有木麻黄防护林树种单一、系统稳定性差、抗逆性弱、病虫害时常发生的实际情况，提出栽培适应性广、抗大风、台风和抗干旱的相思树种并应用于海岸带防护林体系的建设中，对丰富沿海沙地上的造林树种资源，解决因木麻黄连栽造成的生产力下降和地力衰退，改善防护林的树种结构及林分空间结构，提高防护林的抗逆性和防护效能具有重要意义。
