Variations and driving factors of soil respiration components over stand age in boreal birch forests in China

Key Points

• Soil respiration components vary significantly with stand age, indicating vital ecological changes.
• Key findings show that carbon flux levels can differ by up to 50% across different ages of forest stands.
• Assessment using carbon flux measurements indicates strong effects from both biotic and abiotic factors on soil respiration.
• Understanding these variations may help in managing forest ecosystems and in carbon cycle predictions.
