Species associations and community stability of a Tilia mongolica forest
摘要
Abstract
To reveal the dynamic changes of Tilia mongolica population in the community and the succession mechanism of warm temperate deciduous broad leaved forest,a fixed plot of 100 m×100 m was established in Beijing Sizuolou Nature Reserve with concentrated distribution of T.mongolica.The species diversity,species associations and correlations,and community stability of the T.mongolica forest were studied by calculation of α diversity indexes and variance ratio(RV),chi-square test,association coefficient(Ca)test,Pearson's correlation coefficient test,Spearman's rank correlation coefficient test,and M.Godron stability analysis.The results showed that the arbor layer and herb layer in the T.mongolica forest demonstrated obvious dominant species.The shrub layer had higher species diversity,and the arbor layer and shrub layer had more even species distribution.The overall association among 27 dominant species in the community was positive(P<0.05).The significantly positive associations and positive correlations of species pairs were more than significantly negative associations and negative correlations.However,the species associations were loose,and the correlations were weak.The whole community was in an unstable state(Euclidean distance of 20.06),and the stability of different layers in the community was the highest in the herb layer,moderate in the arbor layer,and the lowest in the shrub layer.In conclusion,the T.mongolica community in the Sizuolou Nature Reserve is in an unstable state,while it shows a tendency to develop towards a stable community adaptive to the environmental conditions in this area.关键词
