摘要:
我国红树植物种类约占全世界的1/3,在世界红树植物多样性保护中占有重要地位。但在我国近一半的红树植物呈现出不同程度的濒危状态,科学保护迫在眉睫。本文从濒危红树植物的濒危现状、濒危机制、保护性研究工作和恢复现状等方面对我国濒危红树植物进行了综述,对濒危红树植物的种群扩大和恢复提出了建议。本文认为我国濒危红树植物濒危特点为濒危物种多、濒危等级高、分布范围极为狭窄;我国濒危红树植物的保护性研究工作涉及濒危机制和种苗繁育各个方面,但仅局限于少数物种;引种工作缺乏物种致危因素的科技支撑,同时跟踪监测和人为管护不足。综合考虑濒危红树植物致危因素,将生境保护与人工繁育相结合以最终实现自然更新能力的恢复。

Abstract:
Mangrove species in China account for about 1/3 of the total in the world and they occupy an important position in the protection of mangrove diversity of the world. But at the same time,more than half of mangrove species in China are more and less endangered forming a great pressure on the scientific protection and restoration. In this paper researches on the endangered status and mechanism, and conservation of mangrove plants are reviewed. The endangered characteristics of the mangrove plants in China are more serious than those species in the world in view of high endangered level and highly centralized in extremely narrow zones. The conservation study for the plants in China involves many aspects of endangered mechanism and seedling breeding of a few limited species. Besides, it faces the lack of scientific knowledge for species indroduction and hands of monitoring and maintenances. Conside-ring comprehensively the endangered factors,it is necessary to combine the habitat protection with artificial breeding activities for the natural regeneration ability of endangered mangroves species.
Key words:  marine biology  endangered mangrove  endangered level  threatening factor  natural hybrid  protection strategy
