Abstract:

Ma Kehe forest region is one of the core areas in San Jiangyuan National Nature Reserve. A large number of shrub species distribute in the cold temperate coniferous forest, which have important influence on the succession and restoration of the cold temperate coniferous forest. A series of techniques including relative tests and calculation of the percentage of co-occurrence were used to analyze the interspecific association among 20 dominant shrub species in 40 plots in Ma Kehe forest region of San Jiangyuan National Nature Reserve. The results showed that most of interspecific association of dominant shrub species was significantly negative. Only 69 species pairs were of positive correlation among 190 dominant shrub species pairs, 113 species pairs were of negative correlation, 8 species pairs were of absolute independent correlation. So, only a few dominant shrub species had positive interspecific association, most of them had little opportunity to use the same resources and occupy similar niche in the same community due to their competitions in Ma Kehe forest region.

Key words: San Jiangyuan Nature Reserve, Ma Kehe forest region, cold temperate coniferousforest, dominant shrub species, interspecific association
