缙云山马尾松种群的空间分布格局研究

Study on Spatial Distribution Pattern of Pinus massoniaha Lamb. in Mt. Jinyun

探索马尾松种群的分布格局及动态变化规律,从而指导人工马尾松林的合理经营管理和开发利用。运用扩散系数的t检验、Morisita指数的F检验以及一些种群聚集强度指数来研究缙云山马尾松种群的空间分布格局类型,结果表明缙云山马尾松以大中型个体为主,不同地段的马尾松空间格局分布有所差异,但整体表现不明显,总体表现为随机分布。文章同时指出为避免马尾松林的消失,应分批次种植马尾松幼苗,从而使马尾松种群保持一个平衡的状态。

To explore spatial distribution pattern and dynamic change rule of Pinus massoniaha Lamb.population with the purpose of guiding the rational management and exploitation of artificial pinus forest.The spatial distribution pattern of pinus was studied by applying the test of Dispersal index,F test of Morisita＇s index and some aggregation indexes.The population structure of Pinus massoniaha Lanb.was mainly of big or moderate type,and its spatial distribution pattern were different in different areas.But in general,Pinus massoniaha Lanb.exhibited a random distribution pattern with a relatively weak aggregation intensity,and at the same time,seedlings should be planted intermittently in several batches in order to avoid the disappearance of pinus forest and reach a certain equilibrium.
