摘要

森林恢复正在全球范围内扩大，以提供关键的生态系统服务和碳(C)储存能力。然而，天然林恢复过程中土壤有机碳（SOC）的驱动机制和土壤团聚体稳定性动态机制尚不清楚。本研究选取20年（R20）、32年（R32）、47年（R47）和61年（R61）不同恢复时间的原生林（PF）和天然次生林序列。与R20相比，有机碳含量分别提高了24.78% （R32）、49.90% （R47）、66.42% （R61）和72.11% (PF)，颗粒有机碳（POC）含量分别提高了34.21% （R32）、98.81% （R47）、133.87% （R61）和153.96% （PF）。凋落物是POC的主要来源，一直是森林恢复过程中SOC的重要组成部分。矿物伴生有机碳（MAOC）也随森林恢复而增加，但其积累速率随有机碳水平的升高而减慢。>；随着时间的推移，1毫米的大聚集体逐渐增加。R32、R47、R61和PF的平均重径（MWD）比R20分别提高了35.64%、90.10%、109.90%和117.49%。细根性状和球小球素相关土壤蛋白（GRSP）是团聚体稳定性动态的关键驱动因素。在森林恢复过程中，有机碳的增加、团聚体稳定性的改善和大团聚体POC的积累是同步进行的。

Dynamics of soil organic carbon storage and aggregate stability during natural restoration after clear-cutting in temperate forests

Forest restoration is being scaled up globally to deliver critical ecosystem services and carbon(C) storage capacity. However, it is far less known about the driving mechanisms of soil organic C (SOC) and soil aggregate stability dynamics during natural forest restoration. In this study, an undisturbed primary forest (PF) and a sequence of natural secondary forest with different restoration time of 20 years (R20), 32 years (R32), 47 years (R47), and 61 years (R61) were selected. Compared to R20, the SOC content was increased by 24.78 % (R32), 49.90 % (R47), 66.42 % (R61), and 72.11 % (PF), respectively, and the particulate organic C (POC) content was increased by 34.21 % (R32), 98.81 % (R47), 133.87 % (R61) and 153.96 % (PF), respectively. Litter is the main source of POC, which has always been a major component of SOC during forest restoration. Mineral-associated organic carbon (MAOC) also increases with forest recovery, but its accumulation rate decelerates as SOC levels rise. The proportion of > 1 mm macroaggregates gradually increased over time. The mean weight diameter (MWD) of R32, R47, R61 and PF increased by 35.64 %, 90.10 %, 109.90 % and 117.49 % compared with R20, respectively. Fine root traits and glomalin-related soil protein (GRSP) are key drivers of aggregate stability dynamics. Moreover, the increase in SOC, improved aggregate stability, and POC accumulation in macroaggregates progress synchronously during forest restoration.

期刊介绍： Catena publishes papers describing original field and laboratory investigations and reviews on geoecology and landscape evolution with emphasis on interdisciplinary aspects of soil science, hydrology and geomorphology. It aims to disseminate new knowledge and foster better understanding of the physical environment, of evolutionary sequences that have resulted in past and current landscapes, and of the natural processes that are likely to determine the fate of our terrestrial environment. Papers within any one of the above topics are welcome provided they are of sufficiently wide interest and relevance.
