海南岛热带森林木本植物功能类型的分类研究

The Research on Functional Type of Tropical Forest Woody Plants Classification on Hainan Island,China

通过对海南岛2 282个木本植物的5个功能性状的统计分析,表明:海南岛森林植物的生长型以乔木为主,其次是灌木和木质藤本;<5m、[5m,15m)和[15m,25m)高度级的物种数最多,分别为977种、767种和376种;传播方式主要以动物传播为主,其次为风传播,利用水传播的物种最少,分别为1 158种、91种和31种;有刺的物种数显著低于无刺,分别为165种和2 117种;浆果、核果和蒴果物种数显著高于其他果实类型。热带森林植物不同的功能性状特征体现了植物对不同生境的适应能力。

Statistical analysis of 5functional traits on 2 282 woody plant species on the Hainnan Island showed that the species richness of tree growth-form plays a predominant role,followed by the shrub and linas5m,[5 m,15 m）and [15 m,25 m）height classes in species richness accounted for the most and they are 977,767 and 376,respectively.Animal disperal mode played mainly important role in all the disperal modes,the second was the wind disperal mode,and water disperal mode were the fewest and they are 1 158,91 and 31,respectively.Species richness with no thorns were significantly greater than those of non-thorn and they are 165 and 2 117,respectively.Berries,capsule and nuts played dominant role in fruit types.The findings indicate that the dsitibutions of plants with different functional traits reflected that plants are able to adapt to different habitat conditions on the Hainan Island.
