Abstract

Vegetation restoration has been implemented globally to prevent land degradation and improve soil structure and fertility. The promoting effect of vegetation restoration on soil nutrients has been widely studied; however, controversy remains regarding the responses of soil organic carbon (SOC) and its fractions to different types of vegetation restoration on a global scale. To address this gap, we conducted a meta-analysis of 657 paired observations from 78 papers published worldwide to investigate the effects of vegetation restoration on SOC and its fractions. Our results indicated that vegetation restoration had positive effects on SOC (32.62 %), particularly on large aggregate carbon and mineral-associated organic carbon, and conversion from cropland to forest was the most effective restoration strategy for enhancing SOC. The management patterns, climate factors and site conditions impacted the changes in SOC and its fractions during restoration. Initial soil conditions were the primary factors controlling the impacts of vegetation restoration on SOC and its fractions, followed by climate factors including mean annual precipitation and mean annual temperature (MAT). Compared with areas with a MAT ≥15 °C, regions with a MAT <15 °C were more favorable for SOC accumulation. Additionally, the duration of restoration was positively correlated with an increase in SOC, but the positive effects of vegetation restoration on SOC and its fractions decreased with increasing soil depth. Our findings provide a theoretical framework for understanding SOC and its fractions in the context of vegetation restoration.

植被恢复对土壤有机碳组分的影响：全球荟萃分析

为了防止土地退化，改善土壤结构和肥力，全球都在实施植被恢复。植被恢复对土壤养分的促进作用已被广泛研究；然而，在全球范围内，土壤有机碳（SOC）及其组分对不同类型植被恢复的响应仍存在争议。为了解决这一空白，我们对全球发表的78篇论文中的657对观测数据进行了荟萃分析，以研究植被恢复对土壤有机碳及其组分的影响。结果表明，植被恢复对土壤有机碳（32.62%）有积极影响，特别是对大团聚体碳和矿物相关有机碳，退耕还林是提高土壤有机碳最有效的恢复策略。在恢复过程中，管理模式、气候因子和立地条件影响土壤有机碳及其组分的变化。初始土壤条件是植被恢复对土壤有机碳及其组分影响的主要控制因子，其次是年平均降水量和年平均气温等气候因子。与最低气温≥15°C的地区相比，最低气温≤15°C的地区更有利于有机碳积累。植被恢复持续时间与土壤有机碳增加呈显著正相关，但植被恢复对土壤有机碳及其组分的正向影响随着土壤深度的增加而减弱。本研究结果为理解植被恢复过程中有机碳及其组分提供了理论框架。

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
