摘要：人工?天然混交林是一种人工和天然混合更新形成的混交林。基于以往研究,本文深入分析了人工?天然混交林的发生背景、划分类型和形成过程,系统总结了林分特征和抚育管理方面的研究成果。人工?天然混交林根据林型起源通常被归类为人工林或天然林,缺乏分类和定量化的判定标准,且对该林型的研究不够深入,其培育利用价值亦没有得到充分的评估与重视。因此,本文针对人工?天然混交林存在的主要问题,对未来的研究及经营与利用提出了建议和展望:提出将林分中人工造林和天然更新树种的株数或断面积占比均高于20%作为判定人工?天然混交林的依据;建议加强发展演替过程和机理研究,健全不同类型人工?天然混交林的经营技术体系,结合林业生产实际需求采取针对性地经营管理;在减缓气候变化与实现我国“双碳”目标的时代背景下,应充分发掘和发挥人工?天然混交林的碳汇潜力。
Artificial-natural mixed forest is a kind of mixed forest formed by combining artificial and natural regeneration.Based on previous research,we analyzed the emergence,classification,and assembly process of artificial-natural mixed forests and systematically summarized their forest stand characteristics and management.Usually,artificial-natural mixed forests are classified into artificial or natural forests according to their original forest type and lack classifications and quantitative standards.Moreover,less research on artificial-natural mixed forests and their cultivation and utilization values have not been thoroughly evaluated and stressed.Therefore,given the main problems in artificial and natural mixed forests,we put forward perspectives of future research,management,and utilization.We suggested that the percentage of the number or basal area of both planted tree species and natural regeneration tree species should be more than 20%as the criterion to judge whether a forest stand belongs to an artificial-natural mixed forest.It is necessary to strengthen the study of their succession process and mechanism,improve the management technology system of different types of artificial-natural mixed forests,and adopt targeted management according to the actual demands of forestry production.We should fully excavate and exert its carbon sink potential to mitigate climate change and achieve China's“Carbon Peaking and Carbon Neutrality”goal.
