摘　　要：以广东大亚湾水产资源省级自然保护区红树林资源为研究对象,调查了区内红树林群落资源的起源、空间分布、群落特征等,分析植物种类组成及多样性、现状及成因,发现区内真红树植物有9种,半红树植物8种;在多样性方面,范和港的无瓣海桑和蜡烛果群落的Simpson指数和Pielou指数最高,分别为0.79和0.64。研究表明受温度、盐度、基质等生境条件影响,无瓣海桑自身更新困难,乡土红树植物种类已逐渐在保护区内的无瓣海桑群落内部定居;红树林在造林时需注重生境多样性,充分利用不同的现状本底环境资源,满足不同乡土红树林种类回归定居,增加群落稳定性和物种多样性;提出了需长期开展对无瓣海桑群落的动态监测,以此来对区内红树林采取增、扩、造的模式进行修复和提升。The origin,spatial distribution and community characteristics of mangrove community resources in Daya Bay Aquatic Resources Provincial Nature Reserve of Guangdong Province were investigated. The composition,diversity,status and causes of plant species were analyzed. It was found that there were 9 true mangrove plants and 8 semi-mangrove plants. Simpson index and Pielou index of Sonneratia apetala and Aegiceras corniculatu communities were the highest in Fanhe Harbor,which were 0.79 and 0.64,respectively. It is concluded that due to the influence of temperature,salinity,substrate and other habitat conditions,it is difficult for Sonneratia apetala to renew itself,and native mangrove species have gradually settled in the community in the reserve. Mangrove afforestation should pay attention to habitat diversity,make full use of different current background environmental resources,meet the needs of different native mangrove species returning to be settled down,and increase community stability and species diversity;It is suggested that long-term dynamic monitoring of s. apetala community should be carried out,and mangroves in the area can be restored and upgraded by increasing,expanding and building models.
