By taking Chinese fir plantations in Fushou Forest Farm as the study objects,their spatial structure characteristics were analyzed with three space structure parameters including mingling index,neighborhood comparison and uniform angle index.The results show that the average mingling degree of the stands was 0.138,belonging to the transitional type of zero degree and relatively weak degree mixed;the segregation of tree species was low,and the stability of the stands were not good;the average uniform angel indexes were 0.533,the distribution pattern of the stand was on aggregative distribution;...
