通过标本查阅、野外调查和相关文献分析,得出溧阳深溪芥(119°30′56″E,31°10′26″N)可能是野生香果树在江苏境内残存的唯一分布地点。根据IUCN红色名录评估标准,江苏分布的香果树可列为“极危种”(CR)等级,并结合分布区自然环境条件和人为活动等分析发现,分布区香果树种群规模偏小,自然更新困难、毛竹入侵以及旅游活动等是该区分布的香果树受到威胁的主要原因。因此,建议在该区尽快建立自然保护小区,加强香果树的生境保护,并减少人为干扰。
Based on field survey, specimen examination, and related literature analysis, we find that Emmenopterys henryi only occurs in Shenxikan(119°30′56″E,31°10′26″N), Liyang at present. The species therein was evaluated in light of IU- CN Red List Category and Criteria, and could be classified into critically endangered species (CR). Small population size, difficult natural regeneration, invasion of Phyllostachys edulis, together with tourism activities, threatened this species to a great extent. Therefore, we suggest establishing natural conservation district of this species therein as soon as possible, to strengthen its habitat protection, and minimize anthropogenic interference.
