Huang (Reports, 5 October 2018, p. 80) report significant increases in forest productivity from monocultures to multispecies mixtures in subtropical China. However, their estimated productivity decrease due to a 10% tree species loss seems high. We propose that including species richness distribution of the study forests would provide more meaningful estimates of forest-scale responses.
Huang （报道，2018 年 10 月 5 日，第 80 页）报告称，在中国亚热带地区，从单一树种栽培到多种树种混合栽培，森林生产力显著提高。然而，他们估计由于树种损失 10%而导致的生产力下降似乎过高。我们认为，包括研究森林物种丰富度分布的情况，将为森林尺度的反应提供更有意义的估计。
