解开受火灾影响的生态系统中土壤碳对变暖的响应。该项目旨在揭示澳大利亚受火灾影响的生态系统中土壤碳(C)对变暖的大陆响应模式，并揭示火灾背后的生物地球化学机制S在塑造土壤呼吸的温度敏感性方面所起的作用。S说，火灾已经改变了地球40%以上的地表，在全球变暖的情况下，野火的频率预计还会增加。该项目希望利用多学科的方法，在气候变暖的情况下，产生关于火如何影响土壤到大气的碳通量的新知识。预期成果包括提高利用地球系统模型预测陆地生态系统到大气的碳通量及其对气候的反馈的能力。

Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new knowledge on how fire influences soil-to-atmosphere C fluxes in a warmer climate using a multi-disciplinary approach. Expected outcomes include an enhanced capacity to predict the terrestrial ecosystem-to-atmosphere C fluxes and their feedbacks to climate under increasing frequency of fire using Earth-system models.
