Abstract
Soil respiration (SR) is one of the largest fluxes in the global carbon cycle, exceeding anthropogenic CO2 emission by more than an order of magnitude. Estimation of the heterotrophic component of SR is necessary to assess the carbon balance on the ecosystem and on the regional, national, and global scales. Within the framework of the most important national innovation project “Development of a System of Ground-based and Remote Monitoring of Carbon Pools and Greenhouse Gas Fluxes on the Territory of the Russian Federation,” the first Russian national network is organized to monitor CO2 emission from soils and other linked parameters. The SR values and the relationship with the temperature of the upper 5- to 10-cm layer of soil (TS) are analyzed for the first time on the territory of Russia based on methodologically identical field measurements conducted simultaneously in the summer period (June–August 2023) at 75 monitoring sites in the different ecosystems in the main Russian bioclimatic zones from the tundra to the semidesert. The positive effect of soil temperature on the mean summer SR rate and the maximum monthly SR values is observed in the interval of mean TS from 10 to 20°C. Among the ecosystems studied, the lowest SR values are recorded in tundra and bog ecosystems, while the highest values are in the forest–steppe. Amongst the forest ecosystems, the lowest SR rates are characteristic of larch forests, while the highest SR values are observed in broadleaved forests of the forest–steppe zone. To clarify the regularities obtained, it is necessary to expand studies in all bioclimatic zones, but mainly in agrocenoses, tundra, and steppe ecosystems.
摘要土壤呼吸（SR）是全球碳循环中最大的通量之一，超过人为二氧化碳排放量一个数量级以上。要评估生态系统以及区域、国家和全球范围内的碳平衡，就必须估算SR中的异养生物成分。在最重要的国家创新项目 "俄罗斯联邦境内碳库和温室气体通量的地面和远程监测系统开发 "框架内，组织了第一个俄罗斯国家网络，以监测土壤中的二氧化碳排放和其他相关参数。根据从苔原到半荒漠的俄罗斯主要生物气候带不同生态系统中 75 个监测点在夏季（2023 年 6 月至 8 月）同时进行的方法相同的实地测量，首次在俄罗斯境内分析了 SR 值及其与土壤上层 5 至 10 厘米温度（TS）的关系。在平均 TS 为 10 至 20°C 的区间内，土壤温度对平均夏季 SR 率和最大月 SR 值产生了积极影响。在所研究的生态系统中，冻原和沼泽生态系统的 SR 值最低，而森林草原的 SR 值最高。在森林生态系统中，落叶松林的 SR 率最低，而森林-草原区阔叶林的 SR 值最高。为了阐明所获得的规律性，有必要扩大对所有生物气候区的研究，但主要是对农田、冻原和草原生态系统的研究。
期刊介绍：
Doklady Earth Sciences is a journal that publishes new research in Earth science of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
