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
