Abstract
To explore the association between dominant plant populations,the interspecific associations of dominant tree and shrub populations together with niche plants in an evergreen broadleaf forest of Shiyang Forestry Center,Zhejiang Province were studied based on a 2×2 contingency table using percentage of co-occurrence(C) and association coefficient(D).Results showed that in the tree layer Schima superba,Cyclobalanopsis glauca,Rhododendron ovatum,and Rhododendron latoucheae had higher associations with a majority of the other populations,whereas as Carpinus viminea,Symplocos stellaris,Choerospondias axillaris,Neolitsea aurata,Castanopsis tibetana,and other species had relatively weak associations.Nevertheless,the entire community was relatively stable.In the shrub layer 83.4% of the total 253 species pairs,had a co-occurrence of less than 10%,while 59.3% had association coefficients(D) less than-30%.Most of the shrub species pairs showed weak or no interspecific association.Also,greater intensities of association had larger niche overlap values,whereas weaker associations had smaller niche overlaps.
