红豆树研究现状及濒危保护建议

Research Status and Endangered Conservation Strategy of Ormosia hosiei

红豆树Ormosia hosiei为国家Ⅱ级重点保护野生植物,中国特有种。多生于低海拔常绿阔叶林中,对生存环境要求严格,种群分布狭窄。种子结实率低,结实年龄迟且不稳定,野外自然更新能力较差。由于该物种具有极高的经济价值和开发利用前景,人类干扰及盗伐现象严重,致其分布范围收缩且野外种群数量减少,是一个正在逐步衰亡的物种。文中从种群与生态位、材性、生理、种子萌发技术、育苗技术、混交林造林技术、濒危原因等方面的研究进行综述,并由此提出保护对策。

Ormosia hosiei（Papilionaceae） is a rare and endangered plant, and ranked in gradeⅡkey protected wildlife in China. The species is strict to habitat, distributed narrow range, and grows in low altitude around evergreen broad-leaved forest. Seed production of O. hosiei is low, the reproductive age of the species is late and unstable, and the wild natural regeneration ability is poor. The interference and unlawful phenomenon of human are more and more serious. The distribution range and population size of O. hosiei is believed to be declining and extinctive because of ongoing habitat loss and fragmentation, and the species is being decline. This paper summarized the main results of these studies from the aspects of the population and ecological niche, wood property, physiology, seed germination, seedling technique, mixed forest technology, endangered causes and conservation strategy, and put forward some suggestions for the further study on O. hosiei.
