ABSTRACT

Introduction: Research on the effect of close-to-nature management (CTNM) on stand states and dynamics of forests is crucial for the evaluation of CTNM implemented and sustainable development of forestry.

Outcomes: We analyzed and compared the stand states and dynamics of Masson pine (Pinus massoniana) plantations in the young, middle-aged, and near-mature stages under CTNM eight years after selective cutting and unmanaged control. Both paired-sample T-tests and RDA ordination results demonstrated that the overall stand states with CTNM were superior to the control treatment in all three stages. The interaction of the CTNM and stand age significantly affected The Shannon-Wiener index of diameter class and regeneration density.

Discussion and Conclusion: CTNM and stand age jointly affected the stand state of forests and CTNM accelerated the forest development, which promoted an increase in the heterogeneity of stand parameters and shortened the formation time of a target stand. Greater tree size differentiation and adequate regeneration are particularly important aspects for improving the quality of Masson pineforests during the management processes.

摘要

简介：研究近自然管理（CTNM）对林分状态和森林动态的影响对于评估已实施的CTNM和林业的可持续发展至关重要。

结果：我们分析并比较了在选择性砍伐和不受控制的控制下使用CTNM八年后，在年轻，中年和近成熟阶段马尾松（Pinus massoniana）人工林的林分状态和动态。配对样本T检验和RDA排序结果均表明，在所有三个阶段中CTNM的总体林分状态均优于对照处理。CTNM与林分年龄的相互作用显着影响了香农-维纳直径等级和再生密度指数。

讨论与结论： CTNM和林分年龄共同影响森林的林分状态，CTNM加速了森林的发展，从而促进了林分参数异质性的增加，并缩短了目标林的形成时间。在管理过程中，更大的树木大小差异和适当的再生是提高马森松林质量的重要方面。
