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.

森林覆盖了地球陆地表面的三分之一，占植物碳的80-90%和土壤碳的30-40%。森林碳储量和动态响应并与全球气候变化相互作用（GCC）。最近的树木年轮研究强调了GCC和酸沉积对中欧长期森林生产力的日益恶化的影响。本项目旨在开发和应用新的树木年轮技术，将不同区域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，并为计算长期森林生产力和碳储量提供科学依据，以应对未来的GCC。
