摘  要：
[目的]系统分析海南见血封喉古树资源现状。[方法]依托海南省第2次古树名木普查工作，采用结构分析方法，系统分析见血封喉古树资源分布、生长状况、树高及树龄等特征。[结果]见血封喉在海南分布较广，除三沙市外，均存有见血封喉古树；84.6%分布于100 m以下海拔，砖红壤土地区，且99.2%的呈散生分布于乡村。总体生长状况较好，高达89%个体处于健康状态；共702株古树，一级保护58株，二级保护644株，81.6%树龄在100～199年，最大树龄1 000年。见血封喉古树的树高和胸围呈正态分布，其中树高主要集中在12～26 m，平均树高20.35 m；胸围主要集中在200～400 cm，平均胸围379.0 cm。[结论]该研究可为科学地、有组织地开发见血封喉古树生态旅游提供数据基础，也可为其研究古植被古气候、古植物地理提供重要证据。

摘  要：
[Objective] The aim of this study was to systematically analyze the current situation of ancient tree resources of Antiaris toxicaria in Hainan. [Method] Based on the second survey of ancient and famous trees in Hainan province,the distribution,growth status,tree height and tree age of ancient trees of A. toxicaria were systematically analyzed by structural analysis method. [Result] The results showed that A. toxicaria was widely distributed in Hainan. Except for Sansha city,there were ancient trees of A. toxicaria. 84.6% of them were distributed below 100 m altitude,and 99.2% of them were scattered in rural areas. The overall growth status was good,up to 89% of the individuals were in a healthy state. A total of 702 ancient trees were collected,58trees were first-class protected and 644 trees were second-class protected. 81.6% of the trees were 100-199years old,with the maximum age of 1 000 years. The tree height and chest circumference of the ancient trees were normally distributed,and the tree height was mainly concentrated in 12-26 m,with an average height of20.35 m. The chest circumference was mainly concentrated in 200-400 cm,with an average of 379.0 cm.[Conclusion] This study can provide data basis for the scientific and organized development of the eco-tourism of the ancient trees,and also provide important evidence for the study of paleovegetation paleoclimate and paleovegetation geography.
