Abstract: There are abundant plant resources of psammophilous vegetation on the coast of Xiamen Guanyinshan, including 135 species of vascular plants belonging to 42 families and 113 genera. Compared with the historical investigation data twenty-three years ago, the pioneer plants like Spinifex littoreus, Sporobolus virginicus and others are nearly extinct. In order to change the secondary vegetation status on the coast, the remnant forest and shrub should be protected strengtheningly. And the coastal protection forest system should be constructed on the basis of coastal psammophilous vegetation, thus to improve the environment condition and effectiveness against natural disasters.

Key words: sandy coast, psammophilous vegetation, Xiamen Guanyinshan

摘要： 厦门观音山海岸沙生植被资源丰富，有维管束植物135种，分属于42科113属。但是比较23年前的历史调查数据，鬣刺（Spinifex littoreus）、盐地鼠尾粟（Sporobolus virginicus）等沙滩防风浪固沙护岸先锋植物近乎绝迹。为了改变当地仅存的次生植被现状，应当对残存风水林与灌草丛加强保护，利用海岸沙生植被营造沿海防护林体系，充分发挥其生态效益，达到改善环境条件、有效抗御自然灾害的目的。
