Abstract: >

In this paper, the relative dominance of Populus tremula var. davidiana, Betula platyphylla and Picea wilsonii has been regarded as the measure of the niche overlap. Their final result of competition has been discussed with Lotka-Volterra equation of competition. The results are as follows:

1. The progressing succession of coniferous forest is a process of internal, directional and linear succession. The important power is the competition among dominant plant populations.

2. The result of competition among dominant plant populations has no relation to the inherent growing ability (r) of every population and the first state, and has relation to the competitive coefficient (α)between populations and the accommodeaed capacity (K) of every population.

3. The competition among dominant plant populations. may be regarded as a mathematical theory and a method studying succession of plant community.
