| 摘 要： | 通过采用大小结构图和存活曲线分析种群动态,应用扩散系数、Lloyd的平均拥挤度、聚块性指数和Morisita指数等研究分布格局,采用Greig-Smith方法分析空间格局,对海南岛霸王岭国家级自然保护区内的南亚松(Pinus latteriMason)种群结构与分布格局进行了研究。结果表明,南亚松种群结构属于相对稳定种群,但幼苗、幼树较少;种群存活曲线趋向于DeeveyⅠ型,胸径小于2.5 cm的幼苗成活率较低,幼树存活率开始增大,中龄期种群存活率最高,成龄树期存活率开始下降,至老龄期死亡率达到最大;种群格局整体上呈聚集型;种群格局规模介于100~400 m2。

| Abstract: | Big and small structural picture and survival curve were chosen to research the population dynamics of Pinus latteri.With methods including diffusion coefficient,Lloyd's mean crowding,patchiness index and Morisita's index,the distribution pattern was studied.The space pattern was analysed with Greig-Smith method,population structure and distribution patteren of P.latteri in Bawangling National Nature Reserve,Hainan Island were studied.The results showed that the population structure of P.latteri was a relat... |
