Abstract:
Field data were sampled by the method of contiguous grid quadrate, and t-test of v/m ratio, negative binomial parameter, Green's index, Cassie's index, dispersion index, clumping index, mean crowding index and patchiness index were used to analyse the distribution pattern and its dynamics of Taxus chinensis var. mairei population. The result shows that the distribution pattern was clustering. From sapling to grown-up tree, the clustering degree was decreasing, while the big trees had a random distribution.
