摘要: 针对红树林湿地管理者和研究者中存在的对中国引入的外来红树植物拉关木(Laguncularia racemosa C. F. Gaertn.)是否具有入侵性的矛盾看法,对海南岛分布的拉关木进行了初步调查,并综述了已有的相关研究文献。拉关木在海南岛和华南地区的海岸湿地上生长良好,其植株生长旺盛,繁殖力强,并已自然扩散侵入海南乡土红树植物群落,具有潜在的生物入侵风险。提出对拉关木的潜在入侵性深入研究的几个重点问题,分别为拉关木与海南乡土红树植物的种间竞争机制,拉关木对乡土红树植物群落及其演替趋势的影响;拉关木繁殖体的自然扩散机制;拉关木种群遗传分化与环境适应机制,以期增进对拉关木潜在入侵性及其对海南乡土红树植物多样性潜在威胁的认识。

Abstract: Aim at the contradictory views on the invasiveness of Laguncularia racemosa, the introduced exotic mangrove species in China, in both the researchers and the administrators of mangrove wetlands, the primary survey on the distribution of Laguncularia racemosa in Hainan island was carried out, and the issue based on the related literature was explored. Plants of Laguncularia racemosa grow very well and have high fecundity on the coastal wetlands in Hainan and south China, and some of the individuals have invaded in Hainan native mangrove communities. It has the potential risk of biological invasion. Some important points on research were proposed: The mechanism of competition between Laguncularia racemosa and native mangrove species and the effects of Laguncularia racemosa on the native mangrove communities and its succession trend; the mechanisms of Laguncularia racemosa propagule disposal in natural way; The mechanisms of genetic differentiation of Laguncularia racemosa population and the environmental adaptation, in that to enhance understanding of the potential invasiveness and its potential threat on the biodiversity of native mangrove species.

Key words: exotic species, mangrove tree, Laguncularia racemosa C. F. Gaertn., invasiveness
