国家保护植物厚叶木莲资源调查研究

基于对国家Ⅱ级重点保护野生植物厚叶木莲(Manglietia pachyphylla)部分产地的野外实地考察，并结合相关文献、数据库的分析考证，综述其分类学地位、产地与生境、标本记录、研究进展及致危因素。厚叶木莲自1961年发表以来，迄今已有50多年，其分布区范围从最初认为的广东特有，到与广西共有，其中广东新丰云髻山省级自然保护区的厚叶木莲种群因数量较多，分布较北及海拔较高而颇具特色。因广东省内的厚叶木莲种群多属于衰退种群，需加强就地保护、迁地保护、科学研究及宣传教育。

Resource Investigation of the Key National Protected Species Manglietia pachyphylla

Based on the field investigation of some natural distribution areas of national grade Ⅱ key protected wild plants Manglietia pachyphylla, combined with analysis of related literatures and databases, the taxonomical status, origin and habitat, specimen records, research progress and endangerous factors of this species were summarized.?Since the publication of M. pachyphylla in 1961, it has been more than 50 years. Its distribution area ranged from endemic to Guangdong to sharing with Guangxi. The M. pachyphylla population in Xinfeng Yunji Mountain Provincial Nature Reserve, Guangdong Province is lager, further north distribution and higher in elevation. Most populations of M. pachyphylla in Guangdong are declining populations, it is necessary to strengthen in situ and ex situ conservation, scientific research and education.
