Taking the secondary poplar-birch forest in the mountains of north Hebei as test objects,the reference tree and 4 closest neighboring trees as the spatial structure unit,the width of the tree ring is used for determining the diameter growth to study the relationship between neighborhood comparison and diameter growth.The results show that the most competitive time of the forest trees is 10~20a,which is the best time to manage the forest stand and readjust the density.The reason for formation of Betula platyphylla neighborhood comparison mainly depends on the conditions of the forest growth at its early stage and their competitive ability.Compared with the three neighborhood comparisons,the dominant trees grow better,the middle trees have no obvious growth advantage to the bad state trees.The lower the advantage of the trees is,the lower the relationship between diameter growth and external environment condition is.
