台湾海峡两岸高等植物有116种，其中东岸有99种，西岸92种，海峡两岸物种相似性为78.5%。据海岸基质类型的不同，可分为砂生、盐生、基岩及海岸林和广生境4个生态类群。热带海岸植物水榄、海漆、露兜树等的分布北缘在厦门以南；台湾海峡两岸植物与日本、印度较相似；各种热带、亚热带成分占优势，温带成分较少，分别占总尾数的89.9%和10.1%；台湾海峡两岸植物区系中，热带及亚热带成分从南到北呈递减趋势。There are 116 species of coastal higher plants along either sides of Taiwan Strait, 99species in the east coast and 92 species in the west coast, of which the similarity coeffient accounting for 78.5 %.On the basis of the varous coast substrata four ecologlcal groups maybe divided: sand plant, saline plant, rock and coastal forest plant, and eurylope plant.Thenorthest distribution line of tropical coastal plants such as Brugulera gymnorhiza,Excoecaria agallocha, Pandanus tectorius may be on the south of Xiamen.The flora ofcoastal plants in the Taiwan Stralt are closely relative to that in Japan and India.The tropical and subtropical floral elements are dominanting, the temperate floral element comparatively less, accounting for 89.9% and 10.1 % of the total number of genera.The tropical andsubtropical floral elements in the Taiwan Strait decrease gradually from south to north
