Three typical Emmenopterys henryi communities were selected from Dawei Mountain and Bamian Mountain in Hunan Province. According to the analysis of the important values, species diversity, age structure, life table and survival curve of E. henryi populations, and the comparison of other three E. henryi communities in different regions, we discussed the effect of different latitude and site habitat to the age structure and succession dynamic of E. henryi populations. The results are as follows: (1) the dominant populations of the E. henryi community in Bamian Mountain upstream are Ulmus castaneifolia, E. henryi, Cyclocarya paliuru; and in Dawei Mountain downstream are Dalbergia hupeana, E. henryi, Camellia oleiferawy while the dominant populations of the E. henryi community in Bamian Mountain are Juglans cathayensis, E. henryi, Cyclobalanopsis myrsinifolia. (2) One hundred and eighteen species in 96 genera of 60 families compose the E. henryi community of Dawei Mountain upstream and the E. henryi community of Dawei Mountain contains 76 families 120 genera with 163 species. Their proportions of temperate genera of seed plants are higher than that of tropical genera, which shows the subtropical montane proportion of geographical elements. One hundred and eight species in 95 genera of 61 families compose the E. henryi community of Bamian Mountain. (3) According to the age frequency distribution and the survival analysis, the succession stages of E. henryi population are different in those communities, the E. henryi is a decaying population in the upstream of Dawei Mountain, while it is a stable population in the downstream of Dawei Mountain. It is representative of the growth population in the E. henryi community of Bamian Mountain. (4) Through the comparative analysis, latitude, bareness degree of rock, canopy density, growth conditions of dominant populations in the community, artificial destructiveness are the factors that affect the growth tendency of E. henryi population. In conclusion, we suggest that it should strengthen the further monitoring to the two E. henryi communities in Dawei Mountain. Through the reference to the growth conditions of E. henryi population in Bamian Mountain, proper human intervention and administration to the bareness degree of rock and canopy density are necessary for the two communities to guarantee healthy growth of E. henryi population.
