摘要
探讨了世界红树林植物区系的种类组成及其特点。确认全世界共有红树植物 16科 2 4属 84种 (含 12变种 ) ,其中真红树为 11科 16属 70种 (含 12变种 ) ,半红树为 5科 8属 14种。东方类群有 14科 18属 74种 (含 12变种 ) ,以Aegiceras,Osbornia ,Aegialitis,Bruguiera ,Ceriops,Kandelia ,Scyphiphora和Nypa等属为特征 ;西方类群有 5科 6属 10种 ,具有单种特有科皮利西科Pelliceraceae以及Laguncularia属。中国红树植物区系有 12科 15属 2 6种(含 1变种 ) ,其中特有种 4种。海南的红树植物种类最为丰富 ,占全国的 96 .2 % ;广东次之 ,占 4 2 .3%。台湾记载的红茄苳 (Rhizophoramucronata)其实为红树榄R .stylose之误。
The species composition and characteristics of mangrove flora in the world were reviewed and discussed. The results suggested that the world's mangrove plants have 84 species (including 12 varieties) in 24 genera and 16 families. Of which, true mangrove plants have 70 species (including 12 varieties) in 16 genera and 11 families, and semi-mangrove plants 14 species in eight genera and five families. The Eastern Group has 74 species (including 12 varieties) in 18 genera and 14 families, characterized by the genera Aegiceras, Osbornia, Aegialitis, Bruguiera, Ceriops, Kandelia, Scyphiphora and Nypa etc. The Western Group has only 10 species in six genera and five families, characterized by the endemic one-species family, Pelliceraceae, and the genus Laguncularia. The mangrove flora of China is composed of 26 species (including one variety) in 15 genera and 12 families, four of which are endemic. Hainan is most rich in mangrove species, making up about 96.2% of the Chinese total; Guangdong ranks second, making up about 42.3%. It has been demonstrated that Rhizophora stylosa was mistaken for R. mucronata in Taiwan by previous authors.
