Based on the method of contiguous grid quadrate,the Emmenopterys henryi seedlings field data were sampled,I studied the spatial distribution of them by using the tests of discrete distribution pattern,dispersal index,Morisita’s pattern index,aggregation intensity and Greig-Smiths’ mean variance method.The result showed that the distribution pattern of E.henryi seedlings was clustering.The aggregate intensity was affected greatly by group scale,and dropped with the scale increasing.The trend of the aggregate intensity also declined with the increase of altitude.It was displayed that E.henryi seedlings clumped in 8-16 m² and 50-64 m² from Greig-Smiths’ mean variance analysis.A large number of E.henryi seedlings were less than 40 cm tall,and most of them died before the height of 120 cm due to the strong environmental screening.The tree coverage,shrub coverage,intensity of illumination,atmosphere temperature and atmosphere humidity were the main factor affecting on the growth,survival and distribution of E.henryi seedlings by principal component analysis.In order to promote E.henryi seedlings development,native habitat should be protected and the natural regeneration should be strengthened through by thinning,cleaning up the moss,litter and others.
