Abstract: In Mt. Jinyun three kinds of communities in which Gordonia acuminata population exists were investigated. Based on reproductive allocation and static life table of G. acuminata, the fecundity table and reproductive value table were drown up. Meanwhile we also analyzed each genital index and the important eomponents of reproductive strategy,. The results indicate that for G.acuminata population in cvergreen broadleaved forest, the genital life was the longest and the fitness is the largest. The reproductive value, present reproductive value, residual reproductive value, accumulative residual reproductive value and total value for whole life history of G. acuminata were functions of time, and were restricted by the environments. Those indexes synthetically reflected the pattern and level of influences of interaction between heredity characters and environment factors on reproductive ability of special age individual of G. acuminata population, they also reflected its regular pattern of reproductive dynamics. The negative correlation between the survivorship rate (lx) and the present reproductive value (bx), and the negative correlation between life expectancy (ex) and reproductive invest strategy (ORE) reflected that the larger reproductive investment is, the larger mortality probability is.
