Abstract

Abstract: Forest in the central region of Daxing'an mountains was one of the highest cutting intensity in Inner Mongolia.Through the self recovery of natural forest and implementation of the “natural forest protection project”,the forest quality is improved to a certain extent.With Wuchagou Forest Farm in Xingan league as the research object,the sample survey method was used,the sample plot of 8.8hm² set up in coniferous broad-leaved mixed forest,data were analyzed using Winkelmass 1.0,study on three of spatial structure parameter,named mingling intensity,neighborhood comparison and uniform angle index.Results show that:1.The regional species proportion from high to low order is Betula davurica(52)%,Larix gmelinii(17%),white birch(17%),Quercus mongolica fisch(14%),minly for deciduous broad-leaved forest.2.There was big difference in differentiation,dominant sociales is Larix gmelinii,but it is small in number and poor in mixed ability,the distribution is very concentrated.3.The spatial distribution is reasonable,close to random distribution.

Key words: coniferous broad-leaved mixed forest, mingling intensity, neighborhood comparison, uniform angle index
