摘　　要：通过对平潭岛岩质海岸带裸露山体采取多种方式进行植被恢复试验,结果表明:各树种的保存率均较高,除迎风坡台湾相思和夹竹桃的保存率为85%和88.33%外,其他树种的保存率均达到了94%以上。主要乔木树种侧风坡的生长量均显著大于迎风坡;除迎风坡及风障外的木麻黄和台湾相思受风沙危害,有部分长势较差,出现基干干枯之外,其他树种60%以上均长势优良;肯氏南洋杉受风害影响最小,其次为台湾相思、木麻黄和夹竹桃。风障对造林树种的生长起到了很好的保护效果,风障内的木麻黄保存率、地径和树高生长均显著高于风障外。Experiments of vegetation restoration were conducted on bared mountains by adopting many methods.Result shows that the preservation rate of different tree species are all higher,except that the preservation rate of Acacia mangai and Nerium indicum is 85% ＆amp; 88.33% respectively.The preservation rate of other tree species reached more than 94%,the growth rate of the main tree species is significantly higher than that of the windward slope.Casuarina equisetifolia and Taiwan Acacia were affected by sandstorm;the growth of parts of them are poor,with dry trunk outside.More than 60% of other tree species are growing well.Araucaria cunninghamii were minimally damaged by the wind,followed by Acacia confusa,Casuarina equisetifolia and Nerium indicum.Sand barrier played a very good protective effect on the growth of species.Survival rate,ground diameter and height growth of Casuarina equisetifolia within the sand barrier are all significantly higher than that outside the sand barrier.
