The living fossil species Ginkgo biloba is the sole survivor of the once moderately diverse Gingoalean clade. The natural ecology traits of this species at population and community level are still largely unknown. Seven remnant stands of G. biloba on Mt. Daloushan located on the boundary of Guizhou Province and Chongqing Municipality were investigated and it's community structure characteristics including floristic composition, stratification structure, size structure of main species were analyzed, as were the regeneration characteristics of G. biloba. Eighty two vascular species were recorded in the woody layer; the number of conifers, evergreen broad-leaved trees and deciduous broad-leaved trees were 3, 37 and 42, respectively. Deciduous trees accounted for the vast majority of the relative dominance, and G. biloba was the top dominant species at all stands. The stratification structure of the woody layer at the stands could be distinguished into three layers with G. biloba as the main component of the canopy layer. The size frequency distribution of G. biloba was of the inverse-J type or sporadic type suggesting the possibility of good regeneration, while most of the other main species showed a unimodal pattern indicating weak regeneration. Sprouting traits varied among the G. biloba populations in differing micro-landforms. The ratio of the number of all sprouts to that of main stems was significantly higher in the valley habitat than in the other two areas, the lower side slope and the talus, the proportion of sprouting individuals being the main determination factor. The diameter of the main stem of each individual clone was independent of the total number of stems in that clone. The remnant G. biloba community is seen to be a specifically topographic climax community type developing on unstable micro-landforms which are well watered and well drained. Vegetative reproduction by means of sprouts may have contributed to the extraordinary persistence of G. biloba and the relative stability of the community. Community-level protective measures should be considered, for there are several other endangered species, such as Taxus chinensis, Toona ciliate and Phellodendron chinense living together with G. biloba.
