    摘要:

    增温对微生物残体积累的影响对土壤碳库收支平衡具有重要意义。目前关于增温背景下微生物残体的响应规律和主要影响因素尚未明确。为此，以土壤氨基糖为微生物残体标识物，筛选国内外已发表的12篇文献，收集总氨基糖数据29组，氨基葡萄糖35组，胞壁酸39组，氨基半乳糖25组，利用Meta分析方法，探讨了增温对土壤微生物残体积累的影响及主控因素。结果表明：整体上，增温背景下微生物残体积累有所增加，但响应规律具有生态系统特异性，其中，农田生态系统中微生物残体对增温的响应更为敏感。增温对不同来源氨基糖的影响程度不同，表现为增温显著增加了土壤中氨基半乳糖和胞壁酸的含量，增幅分别为10.3%和5.0%。相应地，增温显著降低了氨基葡萄糖与胞壁酸的比值，说明增温有利于细菌残体的积累。增温背景下，细菌残体占土壤有机碳（SOC）比例显著增加，微生物残体和真菌残体对SOC的贡献比例无显著改变，暗示增温后真菌残体对有机碳库的贡献有所削弱。Meta分析发现，增温幅度是影响微生物残体积累的主要因子，增温幅度小于或等于2℃时，微生物残体的积累数量会增加，增加比例为2.7%～14.6%，而增温幅度大于2℃则会降低微生物残体在土壤中的积累，降低比例为8.0%～14.3%。此外，增温的时间尺度不同（短期、中期、长期）也会对微生物残体产生不同的影响效应。综上，增温会显著影响微生物残体在土壤中的积累动态及其对有机碳库的贡献比例，影响强度和方向又与生态系统类型和土壤深度有关，而增温幅度、增温时间和年均降水量是影响微生物残体积累的重要因素。

    Abstract:

    【Objective】The effect of warming on the accumulation dynamics of microbial necromass is of great significance to the balance of soil carbon(C)pool. However, the impact of climate warming on microbial necromass is poorly understood. Thus, the objective of this study was to evaluate the responses of microbial necromass to climate warming and the main factors controlling this feedback.【Method】In this study, a meta-analysis was conducted to reveal general patterns of climate warming on amino sugars (microbial necromass biomarkers) in soils under grasslands, forests, and croplands. Here, 12 published publications from international and domestic journals were collected and extracted independent observations that met our criteria (29 for total amino sugars, 35 for glucosamine, 39 for muramic acid, and 25 for galactosamine).【Result】The results showed that the overall effects of warming could promote the accumulation of microbial necromass. However, warming effect sizes on microbial necromass were not consistent across different ecosystems, with the most sensitive responses occurring in cropland. The response of fungal and bacterial necromass differed under climate warming. Specifically, warming significantly increased the content of galactosamine and muramic acid, with an increase of 10.3% and 5.0%, respectively. Together with the significant decline in the ratio of glucosamine to muramic acid, the results suggested that warming benefited the accumulation of bacterial necromass compared to fungi. Also warming significantly increased the proportion of bacterial necromass to soil organic carbon (SOC), while the contribution of fungal and total necromass to SOC did not change significantly, suggesting that the contribution of fungal-derived C to SOC was weakened under warming scenarios. Warming magnitude was a key factor affecting the accumulation of microbial necromass. For instance, the accumulation of microbial necromass increased by 2.7%-14.6%, when the warming magnitude was less than or equal to 2℃ relative to unwarmed control. However, when the warming amplitude was greater than 2℃, the accumulation of microbial necromass was decreased by 8.0%-14.3%. Interestingly, the duration of warming was an important factor affecting the accumulation of microbial necromass.【Conclusion】The results demonstrate that warming has significant effects on the accumulation dynamics of microbial necromass and their contribution SOC pool. The intensity and direction of the warming impact are largely dependent upon ecosystem type and soil depth, in which warming amplitude, warming duration, and mean annual precipitation are important factors controlling the sequestration of the microbial-derived C under global climate warming.
