| Abstract: | This paper deals with Correlation between vertical distribution and vertical thermal index of Chinese fir and its mixed species by means of statistics of vertical frequency distribution of Kira's warmth index of the species from 241 samples in Fujian χ 2 test showed that six species obeyed normal distribution, And only two species nearly obeyed normal distribution Whole range of their vertical thermal distribution was 90 5～173 3℃·month And optimal range was 105 5～162 8℃·month by using the formula of peak width at half height |
