以往原位增温研究多采用地上开顶式增温和红外辐射增温，难以模拟对深层土壤（>30 cm）的增温效应。全生态系统增温对地上植被和土壤剖面同步升温，更贴近实际变暖情景。泥炭地是全球单位面积有机碳密度最高的陆地生态系统，但在气候变暖情景下其固碳功能如何变化仍没有明确结论。本研究以四川省红原县若尔盖高寒泥炭地为研究对象，设置对照（CK）、地上增温（AW）、土壤剖面增温（BW）和全生态系统增温（EW）四种处理，探讨不同增温方式对泥炭地生态系统碳通量的影响及其机制。结果表明，土壤温度升高与土壤剖面含水量下降均为调控生态系统碳通量的关键因子。BW和EW均显著促进生态系统呼吸，而AW无显著影响。EW显著降低土壤剖面含水量并促进土壤蒸发，显著降低净生态系统生产力。尽管EW促进植被生长并增加碳输入，但呼吸增强效应超过增温对光合作用的促进效应，导致生态系统固碳能力显著减弱。本研究为准确评估气候变暖背景下高寒泥炭地固碳功能提供了科学依据。

Previous in situ warming experiments have predominantly employed open-top chamber and infrared radiation for aboveground warming， which fail to adequately simulate the warming process in deeper soil （>30 cm）. In contrast， the whole-ecosystem warming， warming both aboveground vegetation and soil profile， represents the most realistic field-scale warming method. Peatland ecosystems are the terrestrial ecosystems with the highest organic carbon density per unit area globally. However， how their carbon sequestration function respond under climate warming remains inconclusive. This study focused on the Zoige alpine peatlands in Hongyuan County， Sichuan Province， China. A field experiment was established with four warming treatments， including control （CK）， above-ground warming （AW）， whole-soil profile warming （BW） and whole-ecosystem warming （EW）. This research analyzed the effects of different warming treatments on ecosystem carbon fluxes in the peatland ecosystem and the regulatory mechanisms. The results showed that elevating soil temperature and decreasing soil profile moisture content were key regulators of ecosystem carbon fluxes. BW and EW all promoted ecosystem respiration （ER）， while AW had no significant effect on ER. EW significantly reduced both soil profile water content and promoted soil evaporation， leading to a notable decrease in net ecosystem productivity （NEP）. Although EW stimulated plant growth and increased carbon inputs， the enhanced respiration effect outweighed the warming-induced stimulation of photosynthesis， resulting in a significant weakened carbon sink. This study provides a scientific basis for accurately assessing the carbon sequestration function of alpine peatlands under climate warming.
