摘　　要：博罗红豆属于国家二级重点保护植物,此前的野外记录表明其生存空间狭窄,且种群规模较小。该次在惠州境内再发现博罗红豆种群,对于揭示博罗红豆极小种群生境要求和进一步研究该物种提供了新的基础。该文采用野外勘查与样方调查相结合的方法,在博罗红豆的新分布点设置样方并进行调查分析。结果表明:新分布点内群落以乔木为优势层,红楠是群落中的优势树种,博罗红豆在群落内不占优势;龄级分析显示,该博罗红豆种群幼苗阶段的个体数量充足,具有较强的更新能力。建议加强管护措施,降低可能对种群产生的干扰。The Ormosia boluoensis is one of the second-class protected plants in China,previous field records indicate that its habitat is narrow,and the population size is small.The rediscovery of O.boluoensis population in Huizhou provides a new basis for further study of this species by revealing the habitat requirements of minimal population.In this paper,the method of field investigation and quadrat survey was used to set quadrat in the new distribution site of O.boluoensis.The results showed that in the new distribution site,trees were the dominant layer,Machilus thunbergii was the dominant species in the community,and O.boluoensis was not dominant in the community.Age-class analysis showed that the sufficient number of O.boluoensis individuals at the seedling stage of this population had strong renewal ability.It is recommended to strengthen management measures to reduce the possible interference to the population.
