摘要：为了解人工种植红树林的生态效应,对2001年种植于广州市南沙区的三种人工混交红树林进行了群落结构和土壤理化性状的调查分析。结果表明:由于红海榄的不耐荫导致样地3无法形成复层结构,但也不排除是红海榄化感作用的影响;无瓣海桑+木榄群落、无瓣海桑+秋茄群落的群落结构和对土壤中重金属的吸收效果优于无瓣海桑+红海榄群落,因此在该实验的立地条件下营造红树林混交林时可以考虑无瓣海桑与秋茄、木榄混交,不应将无瓣海桑与红海榄混交;随着演替的进行,该实验地在无重大干扰的情况下将向着近天然红树林生态系统演化。
In this paper, the community structure and physical and chemical properties of soil are surveyed and analyzed for their ecological effects in three mixed artificial mangroves planted in 2001 in Nansha district Guangzhou. The results show that： Rhizophora stylosa is a shade-intolerant species and its allelopathic effects may exist in site 3, so the forest can＇t change into multistratal forest. Sonneratia apetala ＋ Kandelia candel community and Sonneratia apetala ＋ Bruguiera gymnorrhiza community are superior to the Sonneratia apetala ＋ Rhizophora stylosa community for the former＇s community structure and effect of absorbing heavy metal are better than the latter＇s. Therefore, mangrove Sonneratia apetala mixed with Kandelia candel and Bruguiera gymnorrhiza can be adopted in the site of this experiment, while the scheme of Sonneratia apetala mixed with Rhizophora stylosa is not advocated. With the succession, the plots will be close to natural mangrove ecosystems in the absence of major disruptions.
