| 摘 要： | 采用样方法研究了清凉峰自然保护区境内的野牡丹科珍稀植物方枝野海棠(Bredia quadrangularis)群落分布的特征及其在不同群落中的生长状况,结果表明,方枝野海棠多生长于荫蔽、湿润的沟谷两旁,且在青冈林中的高和地径生长均显著高于杉木、马尾松林.方枝野海棠群落中共有植物214种,其中绝大部分为灌木和草本植物,分别为63种和115种.在水平分布上,方枝野海棠属于聚集分布,该群落的垂直结构性强,物种多样性高,且均匀度及丰富度均较高. |
| 关 键 词： | 方枝野海棠 生境 群落特征 |

| Abstract: | Distribution properties and growth of Bredia quadrangularis population under different forest structures was studied by quadrat in Qingliangfeng Nature Reserve, Zhejiang province. The results showed that B. quadrangularis mainly distributes in both sides of the shaded and wet valley. The diameter and height growth of the plant in Cyclobalanapsis glauca forest are significantly higher than that in Cunninghamia lanceolata forest and Pinus massoniana one. There are 214 species in B. quadrangularis community, most of them are shrubs(63 species) and herbs(115 species). The spatial distribution pattern of the community orB. quadrangularis is aggregation distribution, and it has strong vertical structure, high Simpson diversity, Pielou evenness and richness index. |
