东江虎门入海口红树林的群落特征及生态恢复

Community Characteristics and Ecological Restoration of Mangrove at Estuary of Dongjiang River in Humen

以广东省东江虎门入海口处的红树林植物为研究对象,采取样线和样方相结合的方法调查群落,初步分析了东江虎门入海口处红树林植物的群落特征。结果表明:东江虎门入海口红树林有15种维管束植物,隶属于11科3属。所有的红树林植物可归为3个群落类型:桐花树群落、老鼠簕群落、秋茄+桐花树+老鼠簕群落。并对该地红树林的生态恢复提出了相应的建议。

The results showed that：in the mangrove at the estuary of the Dongjiang river,there were 15 species of vascular plants,belonging to 11 families and 3 genera. According to community physiognomy and dominant species,all mangrove plants could be divided into the following three community types：Aegiceras corniculatum community,Acanthus ilicifolius community,and Kandelia candel ＋ Aegiceras corniculatum ＋ Acanthus ilicifolius community.
