Abstract:: A Pinus tabulaeformis forest which was established in Heilihe natural reserve with the area of 1.96hm² in Inner Mongolia was investigated by sampling methods.The objective of the study was to obtain a better understanding of the structure of Pinus Tabulaeformis Forest.Spatial patterns of main tree species were analyzed by uniform index analysis,point pattern analysis and angle index analysis.Pinus tabulaeformis was dominant species in arbor layer.The main concomitance species were Tilia mandshurca,Quercus mongolica,Acermono and Betul platyphylla.Main concomitance species showed a concentrated distribution in the forest.Pinus tabulaeformis showed an aggregated distribution at scale of 1～65m and random distribution at scale of 65～70m.The saplings and the small trees of Pinus tabulaeformis showed an aggregate distribution,but the big trees showed a random distribution.Every method has its own superiority.This study will supply theoretic foundation for the future research.
