摘　　要：红树植物生长在热带、亚热带海岸滩涂上。健全的红树植物生态系统是人类持续利用红树林的必要条件。如何保护、维持红树林的生态系统及其遗传健全性已成为红树林生态学家最关心的问题。红树植物当前的地理分布格局及形成原因是生态学家和保护生态学家的研究重点。文中介绍了近些年来红树植物亲缘地理学研究概况,包括地理隔离对红树植物分布格局的影响、基因交流受阻隔以及引起红树群体遗传结构变化的原因等内容;阐述了地质历史引起地形地貌变化、地理隔离、繁殖体扩散及生境环境等因子影响红树群体遗传演化的机制;探讨了红树植物亲缘地理学未来研究的重点,以期为红树植物保护和相关研究提供参考。Mangroves grow on the tidal land at sub-tropical and tropical regions, and the sound mangrove ecosystem is the prerequisite for humans to utilize the mangroves in a sustainable way. How to protect and maintain mangrove ecosystem and its genetic soundness is the main concern of the mangrove ecologists. The present geographic distribution of mangroves and the research of ecologists and conservation ecologists. factors contributing to the distribution are the focus of This paper introduced the research progress in the mangroves phylogeography, including the impact of geographic division on mangrove distribution, the reasons for gene exchange blocking and genetic structure change of mangroves. Then it expounded the mechanisms for the influences of the combinations of factors, including geohistory, geographic division, propagule dispersal, biotope, etc. on the evolution of the mangroves. The future focus in the future mangrove phylogeopgraphy research was discussed, with the aim to provide the basis for mangroves conservation and related research.
