| 摘要: |
| 应用样方调查法，对海南尖峰岭半落叶季雨林的物种组成结构及多样性特征进行研究。结 果表明，在总面积5 000 m2 的样方中，共记录到胸径≥ 1 cm 的植株2 565 株，除 3 个种未确定种名外， 其他分属26 科 42 属 46 种。以大戟科(Euphorbiaceae) 和桑科(Moraceae) 为优势科，以刺桑(Streblus ilicifolius)、布渣叶 (Microcos paniculata) 和鹊肾树 (Streblus asper) 为优势种。当取样面积达到 3 850 m2 或 取样植株数达到 1 800 株时，记录到的物种数有 47 种，占总物种数的 95.92%。样地内所有植株平均胸径 为 6.36 cm，径级分布呈倒“J”型。刺桑、赤才(Lepisanthes rubiginosa) 和粗糠柴(Mallotus philippensis) 的空间分布呈较强的聚集性，布渣叶和鹊肾树的分布较均匀。Shannon-Wiener 多样性指数和Simpson 多 样性指数较低，样地的物种种类较少，植株分布的不均匀。 |

| Abstract: |
| The characteristics of species composition, structure and species diversity of the semi-deciduous forest in Jianfengling, Hainan Island were studied by plot method. The results showed that, in the sample plot of 5 000 m2, a total of 2 565 individuals, with stem diameter at breast height (DBH) ≥ 1.0 cm, belonging to 26 families, 42 genera and 46 species were recorded, except of 3 unidenti?ed species. The dominant families were Euphorbiaceae and Moraceae. The dominant species were Streblus ilicifolius, Microcos paniculata and Streblus asper. When the sampling area was 3 850 m2 or the sampling individuals were 1 800, 47 species and up to 95.92% of all species were counted in the plot by species–area and species–individual curves. The average DBH of all stems was 6.36 cm and the DBH size class distribution showed a typical inverse-J distribution. The spatial distribution of Streblus ilicifolius, Lepisanthes rubiginosa and Mallotus philippensis were strongly clustered. The distribution of Microcos paniculata and Streblus asper were more uniform. Both Shannon-Wiener diversity index and Simpson diversity index were relatively low. There were fewer species in the plot and species distribution was relatively uneven. |
