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

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.
