Species segregation function \( \hat{\varPsi}^{\prime }(r) \) and size segregation function \( \hat{Y}^{\prime }(r) \) for the four Chinese example research plots Daqingshan (plot a), Jiaohe (plot b), Jiulongshan (plot a) and Xiaolongshan (plot c), where \( \hat{Y}^{\prime }(r) \) was estimated from the mean allometric coefficient \( \overset{\sim }{m} \). RMSE is the root mean square error
