Growth characteristics of Chinese fir in pure and mixed forests

Abstract: An analysis on growth characteristics of Chinese fir in pure forest and mixed forest of Chinese fir and Fokienia hodginsii was made.The results showed that the increments of tree height , DBH and tree volume of Chinese fir pure forest were similar to mixed forest in the first 4 years , but those of pure forest rapid fell later on.Compared with pure forest , tree volume increased by 70.10 %when 16-yearold , peak growth appeared earlier , peak value bigger and sustainable time over the fast-growing period longer in mixed forest.
