摘　　要：为了掌握海南岛母生种质资源的分布、数量和种群特征,为今后母生资源的保护利用提供参考,采用踏踩、线路调查等方法对海南岛18个市县(除三沙市外)进行了母生种质资源调查。结果表明:母生主要在海南岛南部及西南部分布,且较为密集,特别是低海拔的沿海区域。乐东县的母生储量为全岛最高,达45680棵。母生古树以在昌江县霸王岭保存为最好,古树树高主要分布在21~30 m,胸径集中在20~60 cm的范围,但存在人为砍伐的现象。母生优势种群总平均树高为21.76 m,总平均胸径为34.76 cm,总平均冠幅为4.36 m×4.42 m。In order to grasp the distribution,quantity,and population characteristics of Homalium hainanense in Hainan Island and provide reference for the protection and utilization of Homalium hainanense,a survey of Homalium hainanense resources in 18 cities and counties in Hainan Island(except Sansha city)is conducted.The results show that Homalium hainanense is mainly distributed in the southern and southwestern of Hainan Island,and it is dense,especially in low-altitude coastal areas.And the highest storage is in Hainan Ledong County with 45680 trees.The Homalium hainanense old trees are best preserved in the Bawangling Nature Reserve.The height of the old trees is mainly distributed in the range of 21~30 m,and the breast diameter is concentrated in the range of 20~60 cm,but there has a phenomenon that is man-made felling.About the Homalium hainanense dominant population,the total average tree height of Homalium hainanense dominant population is 21.76 m;the total average breast diameter is 34.76 cm,and the total average crown width is 4.36m×4.42m.
