An individual-based study framework was used to estimate the productivity-diversity relationships at both species and community levels. A homogeneous Thomas point process was used to evaluate the significance of productivity-diversity relationship deviating from the neutral.<br \/>\n<strong>Results<\/strong> At the species level, most of the studied species exhibit neutral productivity-diversity relationship in both forest plots. The percentage of species showing negative productivity-diversity relationship approaches linearly a peak value for very close neighborhoods (the secondary forest plot: r\u2009=\u20093 m, 38%; the old-growth forest plot: r\u2009=\u20094 m, 42%), and then decreases gradually with increasing spatial scale. Interestingly, only a few species displayed positive productivity-diversity relationship within their neighborhoods. Dominant species mainly exhibit negative productivity-diversity relationship while tree species with lower importance values exhibit neutral productivity-diversity relationship in both forests. At the community level, a consistent pattern of productivity-diversity relationship was observed in both forests, where tree productivity is significantly negatively associated with local species richness. Four biomass-dominant species (<em>Juglans mandshurica<\/em> Maxim., <em>Acer mono<\/em> Maxim.,<em>Ulmus macrocarpa<\/em> Hance and <em>Acer mandshuricum<\/em> Maxim.) determined a negative productivity-diversity relationship at the community level in the secondary forest plot, but only one species (<em>Juglans mandshurica<\/em>) in the old-growth forest plot.<br \/>\n<strong>Conclusion<\/strong> The productivity-diversity relationship is closely related to the dominance of individual species at the species level. Moreover, this analysis is the first to report the roles of biomass-dominant species in shaping the productivity-diversity relationship at the community level.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nProductivity-diversity relationship, Species dominance, Individual species, Homogeneous Thomas point process<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-018-0780-0'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nCheng, Y., Zhang, C., Zhao, X. et al.
