Abstract: Niche characteristics of the two natural secondary communities which were chosen in Wuling Mountain Nature Reserve were analyzed by taking community composition types as one-dimension resource states.Niche characteristics of natural secondary forest were used to reveal the phases and the direction of the populations in the succession process on the basis of the substitution of time with space.The results showed: 1) The plant Community typeⅠand typeⅡare in the different succession stages of the same succession sequence,and typeⅡ is the later stage of typeⅠ.2) The Betula platyphylla presented the type of niche declining population; the populations of Tilia mongolica and Quercus mongolica presented the type of niche invasive population; all the populations of Betula platyphylla,Betula,dahurica,Betula albo-sinensis and Acer truncatum presented the type of niche stable population; the Ulmus macrocarpa presented the type of niche sensitive population.3)TypeⅡhave higher interspecies niche overlap value and more extensive competition than typeⅠ.4)The populations of birch of typeⅡwould decline in the succession process,and the community would become the mixed forest of Linden and Oak.

Key words: Wuling Mountain, natural secondary forest, succession, niche breadth, niche overlap
