珍稀濒危植物濒危机理研究进展

Research progress on endangered mechanism of rare and endangered plants

植物是生态系统的重要组成部分,在生态系统循环中发挥了不可替代的作用,是一种重要的自然资源和战略资源。珍稀濒危植物,就是由于内在机理和外在机理的共同作用下,出现数量急剧下降甚至接近消亡的植物。如对其不采取及时的保护措施,将很快灭亡。基于国内外珍稀濒危植物研究现状,从内在和外在两个机理阐述珍稀濒危植物濒危机理的研究进展,提出了珍稀濒危植物濒危机理研究中存在的问题及今后的发展前景。

The plant is one of the most important parts of ecosystem, plays an irreplaceable role in the circulation of ecosystem, and it is an critical natural and strategic resources. Rare and endangered plants, are due to the joint function of intrinsic and external mechanisms, the number of them falls down dramatically, or they are even close to extinction. If there is no urgent protective measures, they will perish soon. Based on the research status of rare and endangered plants at home and abroad, the paper elaborated the research progress of endangered mechanism of rare and endangered plants from intrinsic and extrinsic mechanisms, put forward the problems and prospects of research on endangered mechanism of rare and endangered plants.
