<b>Symbiosis type in nitrogen fixing trees determines greenhouse gas emissions: a global meta-analysis</b>

N-fixing trees is widely spread for planting forest and agroforestry ecosystems due to their advantages for improving soil quality and carbon sequestration. However, the impact of N-fixing trees on N₂O, CH₄, and CO₂fluxes relative to non-fixing trees remains uncertain. We use meta-analysis to discover this important knowledge gap. Specific description for this study and related dataset and code were attached.固氮树木（N-fixing trees）凭借其改善土壤质量、提升碳固存能力的优势，被广泛应用于森林与农林业生态系统的营建。然而，相较于非固氮树木，固氮树木对一氧化二氮（N₂O）、甲烷（CH₄）与二氧化碳（CO₂）气体通量的影响仍尚不明确。针对这一重要的研究空白，本研究采用元分析（meta-analysis）方法开展探究。本研究的详细说明、相关数据集及配套代码已随附提供。
