| Abstract: | Based on the ecostratigraphic method the composition of organisms, the diversity and relative abundance, the properties of the substrata and the distribution of the Yunnanella-Yunnanellina community of Xikuangshan stage, late Devonian in central Hunan are analysed. The life property, the distribution and relationship of some organisms with the environment are discussed according to their size-frequency histograms and survivorship curves. The life habits, trophic structure and environment of this community are also analysed in this paper. |
