Abstract: Based on the inventory of the Larix gmelinii forest sample plots in Greater Khingan Mountains,Inner Mongolia,the method of point pattern analysis was employed to study the impact of different cutting methods on the distribution pattern of community standing trees in Larix gmelinii forest,the Larix gmelinii tree species and the different age-class standing trees.The results showed that1)Different cutting methods have great impact on the distribution pattern of community standing trees in Larix gmelinii forest;In Larix gmelinii virgin forest,the distribution pattern of standing trees presented stochastic mode on 0-2m scale,it presented significant cluster mode on >2m scale;In successive cutting forest,the distribution pattern of standing tree presented cluster mode on 2-9m,it presented stochastic mode on other scale;In clear cutting forest,the distribution pattern of standing tree presented cluster mode on 0-19m scale,it presented stochastic mode on >19m scale;2)Successive cutting method have little impact on the distribution pattern of Larix gmelinii tree species,while the impact of clear cutting method is on the opposite;3)Different cutting methods have great impact on age-class1,successive cutting method has little impact on age-class2,while clear cutting is on the opposite and the successive cutting method has little impact on age-class3.
