JapanFlux2024 RU-NeF Neleger larch 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.为获取通过调控多年冻土（permafrost）扰动以实现温室气体（Greenhouse Gas，GHG）减排所需的基础信息，需对扰动区域的温室气体收支变化进行监测，并对其影响开展定量评估。由于多年冻土扰动由上覆生态系统受扰引发的热平衡失衡所导致，因此需同时监测生态系统扰动引发的地表热、水平衡变化。本研究旨在通过长期监测，明确多年冻土区森林扰动对地表热、水、二氧化碳（CO2）收支及多年冻土动态的影响。本研究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，开展了地表热、水与二氧化碳收支的长期连续监测。

背景概述

该数据集是一个长期监测项目，旨在研究俄罗斯联邦雅库茨克附近落叶松林中森林扰动（如火灾和采伐）对表面热、水、CO2预算及永久冻土动态的影响。其关键特点是通过连续观测，为永久冻土扰动控制提供基础数据，以支持温室气体减排策略的定量评估。数据集聚焦于环境变化监测，强调多变量同步跟踪，以理解生态系统扰动与永久冻土热平衡之间的关联。
