JapanFlux2024 RU-NeB Neleger Burnt Forest

In order to obtain basic information for GHG reduction by permafrost disturbance control, it is necessary to monitor changes in the GHG budget at the disturbance site and to quantitatively evaluate the impact.
Since permafrost disturbance is induced by thermal equilibrium collapse due to disturbance of the overlying ecosystem, changes in the surface heat and water balance due to ecosystem disturbance should also be monitored simultaneously.
The purpose of this study was to determine the effects of forest disturbance on the surface heat, water, and CO2 budgets and permafrost dynamics in a permafrost area through long-term monitoring.
Long-term continuous monitoring of surface heat, water, and CO2 budgets was conducted in larch forests, fire sites, and logging sites near Yakutsk, Russian Federation.

为获取通过管控多年冻土（permafrost）扰动以实现温室气体（Greenhouse Gas, GHG）减排所需的基础数据，需对扰动区域的GHG收支变化开展监测，并对其影响进行定量评估。
由于多年冻土扰动由上覆生态系统受扰引发的热平衡坍塌所诱发，因此还需同步监测生态系统扰动导致的地表热水平衡变化。
本研究旨在通过长期监测，厘清多年冻土区森林扰动对地表热、水及二氧化碳（CO₂）收支与多年冻土动态的影响。
研究团队在俄罗斯联邦雅库茨克周边的落叶松林、火烧迹地与采伐迹地中，开展了地表热、水及CO₂收支的长期连续监测工作。
