报告人简介：
Huth is a full professor at the Helmholtz Centre for Environmental Research (UFZ). His primary research focuses on the dynamics of forests, including disturbances, and the carbon balances of vegetation. He is renowned for developing a family of dynamic forest models for species-rich forests, particularly tropical rain forests. The most notable models created by Huth are FORMIND and FORMIX3. These models are process-based, employing an individual-based approach to describe the development of each tree in the forest. The models calculate photoproduction of leaves, respiration, and litter fall to determine the growth of individual trees. Tree growth and regeneration in these models critically depend on the local light conditions within the forest environment. Huth's innovative work in developing physiologically grounded, individual-based forest models has significantly advanced our understanding of the complex dynamics governing diverse forest ecosystems.

Forests play an important role in the global carbon cycle as they store large amounts of carbon. Understanding the dynamics of forests is an important issue for ecology and climate change research. In this presentation we will give an overview on the knowledge on global forests and their carbon balance. We will explain typical methods to model forests and their dynamics. Using an individual based forest model (FORMIND) we developed an approach to simulate dynamics of around 410 billion individual trees within 7.8 Mio km² of Amazon forests. We combined the simulations with remote sensing observations from Lidar in order to detect different forest states and structures caused by natural and anthropogenic disturbances. Under current conditions, we identified the Amazon rainforest as a carbon sink, gaining 0.56 Gt C per year. We found that successional states play an important role for the relations between productivity and biomass. Simulated values can be compared to observed local carbon fluxes.
