菌根呼吸（Mycorrhizal respiration，RMyc）是土壤呼吸的重要组成部分，显著影响陆地生态系统碳循环过程。然而，不同生态系统中RMyc的贡献潜力及主要影响因子尚不明确。本文整合分析了41篇文献中的105组数据，采用网格排除法区分土壤呼吸组分，量化了RMyc对土壤自养呼吸（RAuto）、土壤总呼吸（RT）的平均贡献，并比较丛枝菌根（Arbuscular Mycorrhizal，AM）呼吸和外生菌根（Ectomycorrhizal，ECM）呼吸贡献的差异及其影响因子。。研究发现：RMyc对RAuto、RT的平均贡献率分别为38.55%和16.87%。其中AM、ECM的平均贡献分别为16.78%（2.48%~32.00%）和16.73%（3.00%~54.47%）。RMyc速率与绝对经度、年降雨量、土壤总氮、土壤总磷显著负相关，与土壤pH值、细根生物量显著正相关。总体而言，RMyc是RAuto和RT的重要组成部分，受环境因子、土壤养分供给、共生关系的影响。本研究从全球尺度表明菌根呼吸对土壤碳通量的贡献，为完善土壤碳循环提供科学依据。

Abstract

Mycorrhizal respiration （R_Myc） significantly affects the carbon cycling in terrestrial ecosystems， yet its contribution potential and main influencing factors remain unclear. In this study， a meta-analysis was conducted by using 105 datasets from 41 publications. By employing a mesh exclusion method to distinguish soil respiration components， we quantified the average contribution of R_Myc to soil autotrophic respiration （R_Auto） and total soil respiration （R_T）， and compared the differences between arbuscular mycorrhizal （AM） and ectomycorrhizal （ECM） contributions. The results showed that the average contribution rates of R_Myc to R_Auto and R_T were 38.55% and 16.87%， respectively. Specifically， the average contributions of AM and ECM to R_T were 16.78% （ranging from 2.48% to 32.00%） and 16.73% （ranging from 3.00% to 54.47%）， respectively. Correlation analysis indicated that the R_Myc rate was significantly negatively correlated with absolute longitude， mean annual precipitation， soil total nitrogen， and soil total phosphorus， while it was significantly positively correlated with soil pH and fine root biomass. Over all， R_Myc is an important component of soil respiration， and is affected by environmental factors， soil nutrient supply， and symbiotic relationships. This study revealed the contribution of mycorrhizal respiration to soil carbon fluxes at a global scale， providing a scientific basis for improving soil carbon cycle models.
