摘要
山地云雾林是一种脆弱的生态系统，拥有丰富的生物多样性，是必不可少的碳调节器。然而，关于这些森林的碳储存潜力及其在整个保护梯度上的变化模式的信息很少。研究确定了不同碳库的碳储量潜力、碳库的贡献及其与森林和土壤保持程度的关系。结果各群落有机碳储量在145.9 ~ 279 Mg C ha−1之间。土壤是主要的碳库（68.08 ~ 198.1 Mg C ha−1），地上生物量次之（42.87 ~ 116.74 Mg C ha−1），凋落物和根系的贡献较小。由于这些群落中木材和薪材的开采水平，地上生物量对碳储量的贡献较低。土壤库具有较高的碳储存潜力，主要取决于O层的存在，O层厚度为8 ~ 10 cm，形成了mull型腐殖质和深层有机矿物表层层，其含碳量为10 g kg−1，腐殖质化程度不同。粘土-腐殖质复合体的形成维持了碳的稳定和深层地表层（深度在20至38厘米之间）的形成。结论MCF的固碳潜力与地表发育的有机层和高碳含量的深层A层有关。尽管有森林管理，但这些层的保存（反映在空中生物量上）表明，由于碳稳定，土壤具有恢复力，这归因于抗性有机化合物的组成和粘土-腐殖质复合体的形成，从而减少了侵蚀退化的影响。这表明MCF的条件仍然维持着支持碳固存的生态和生物地球化学过程，并受到墨西哥queremadaro的Sierra Gorda生物圈保护区保护政策的管制。
Carbon storage in mountain cloud forest communities, Jalpan de Serra, Querétaro, México
Background
Mountain cloud forests (MCF) are vulnerable ecosystems that harbor considerable biodiversity and are essential carbon regulators. However, information is scarce on the carbon storage potential and its patterns of variability across the conservation gradient in these forests. This study determined the carbon storage potential, the contribution of different pools, and their relationship with the degree of forest and soil conservation.
Results
The organic carbon storage of the communities ranged from 145.9 to 279 Mg C ha−1. Soil was the primary pool (68.08–198.1 Mg C ha−1), followed by above-ground biomass (42.87 – 116.74 Mg C ha−1), while the contribution of litter and roots was less. The contribution of above-ground biomass to the carbon stock was low due to the level of timber and fuelwood extraction present in these communities. The high carbon storage potential of the soil pool is determined by the presence of the O horizon, with a thickness of 8–10 cm, forming mull-type humus and a deep organo-mineral surface horizon with a high carbon content > 10 g kg−1, and with varying degrees of humification. The formation of clay-humus complexes maintains carbon stabilization and the formation of deep surface horizons (between 20 and 38 cm deep).
Conclusion
The results show that the carbon sequestration potential of the MCF is found in the soil associated with the organic horizons that develop at the surface and the presence of deep A horizons with high carbon content. The conservation of these layers, despite forest management, reflected in the aerial biomass, demonstrates the resilience of the soil due to carbon stabilization, attributed to the composition of resistant organic compounds and the formation of clay-humus complexes, which reduce the impact of degradation from erosion. This indicates that the conditions of the MCF still sustain the ecological and biogeochemical processes that support carbon sequestration and are regulated by the conservation policies of the Sierra Gorda Biosphere Reserve, Querétaro, Mexico.
期刊介绍：
Carbon Balance and Management is an open access, peer-reviewed online journal that encompasses all aspects of research aimed at developing a comprehensive policy relevant to the understanding of the global carbon cycle.
The global carbon cycle involves important couplings between climate, atmospheric CO2 and the terrestrial and oceanic biospheres. The current transformation of the carbon cycle due to changes in climate and atmospheric composition is widely recognized as potentially dangerous for the biosphere and for the well-being of humankind, and therefore monitoring, understanding and predicting the evolution of the carbon cycle in the context of the whole biosphere (both terrestrial and marine) is a challenge to the scientific community.
This demands interdisciplinary research and new approaches for studying geographical and temporal distributions of carbon pools and fluxes, control and feedback mechanisms of the carbon-climate system, points of intervention and windows of opportunity for managing the carbon-climate-human system.
Carbon Balance and Management is a medium for researchers in the field to convey the results of their research across disciplinary boundaries. Through this dissemination of research, the journal aims to support the work of the Intergovernmental Panel for Climate Change (IPCC) and to provide governmental and non-governmental organizations with instantaneous access to continually emerging knowledge, including paradigm shifts and consensual views.
