Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity

森林覆盖了地球陆地表面的三分之一，占植物碳的80%-90%，土壤碳的30%-40%。森林碳储量和动态应对全球气候变化并与之相互作用(GCC)。最近的年轮研究突显了GCC和酸沉降对中欧森林长期生产力的恶化影响。该项目旨在开发和应用新的树木年轮技术，将不同地区的碳和养分的生物地球化学循环与长期森林生产力联系起来，并为应对未来GCC的森林长期生产力和碳储量的核算提供科学依据。

Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This project seeks to develop and apply novel tree ring technologies for linking biogeochemical cycles of carbon and nutrients to long-term forest productivity in different regions, and to provide a scientific basis for accounting for long-term forest productivity and carbon stocks in response to future GCC.
