摘要
由于外来红树植物无瓣海桑(Sonneratia apetala)和拉关木(Laguncularia racemosa)具有速生特性,因此被广泛应用于红树林生态恢复中,并卓有成效。但是,这两种红树植物是否具有生态入侵性已经成为近年来的研究热点。全面梳理、分析了无瓣海桑和拉关木的各种可能扩散行为的生物学过程,结果表明,在中国这两种红树植物尚不具有生态入侵危害,仍然可以作为中国红树林修复工作重要的树种资源。但是,引进任何外来的生物,都应该有风险防范的意识,加强跟踪监控,确保生态安全。目前,可以利用先进技术,提高对这两种外来红树植物的监控水平,在有把握控制的情况下,采取因地制宜、分区施策、分类指导的方法,在恢复红树林生境条件困难的地域,可以适当引种这两种红树植物并进行推广,以满足现阶段国家红树林生态建设的重大需求。
The exotic mangrove plants Sonneratia apetala and Laguncularia racemosa have been widely used in mangrove ecological restoration due to their quick growth.However,whether these two species have ecological invasion has become a major research hotspot in recent years.In this paper,the biological processes of various possible spreading behaviors of these two species were analyzed comprehensively.The results showed that these two mangrove plants did not have ecological invasion hazards in China,and could still be used as the important species for the mangrove restoration in China.However for any exotic organisms introduction work we need to have a sense of risk prevention.Tracking and monitoring to ensure ecological security must be strengthened.At present,advanced technology could be used to improve monitoring means,carrying out the introduction project properly in the mangrove difficult habitat conditions under the controllable circumstances.According to different conditions,we sould take different planting policy and classification guidance methods,so as to meet the great demand of ecological construction of mangrove in our country.
