摘　　要：无瓣海桑Sonneratia apetala是引进的外来红树林植物,优良的速生红树林树种,1985年从孟加拉国引入我国,2002年广西钦州从湛江引进无瓣海桑并在沿海进行规模化造林。目前,无瓣海桑对生态的影响尚无定论。本文通过查阅文献资料和实地调查,从钦州自然环境条件、无瓣海桑在钦州的发展历程,及无瓣海桑自身的适应性分析,认为无瓣海桑在钦州能够实现自然更新,能够快速占领宜林地甚至入侵至原生红树林群落,在钦州沿海表现出了一定的入侵性,对沿海红树林生态系统造成了影响,需要采取措施进行防控。并针对目前防控困境提出了应对措施。Sonneratia apetala is a mangrove plant,also an excellent fast-growing tree,which was introduced into China from Bangladesh in 1985,And had been planted for large-scale afforestation in the coastal area of Qinzhou Since 2002.As an alien plant,the ecological effects of Sonneratia apetala is not determined.This paper,combining a lot of material and field survey,analysis the changes of natural environment condition and the adaptability of Sonneratia apetala,considers that Sonneratia apetala could successfully realize natural renewal,rapidly occupy the area suits to forestry even invade into primitive mangrove community.Sonneratia apetala has caused biological invasion and ecological risk in Qinzhou coastal beach,and it need to take prevention and control measures to restrict the population to extent quickly.The paper also propose countermeasures for the current prevention and control dilemma.
