09:00  T. Rötzer (TU Munich): Process-based forest models and the software BALANCE

            – Introduction

At the beginning an introduction to process-based modelling and an overview of existing process-based models is given. The physiological growth model BALANCE will be explained in detail showing processes, principles and functional chains of all modules as well as adaptation and validation re­sults. The application of the model is demonstra­ted by an example. Some further examples give infor­ma­tion on the reaction of forest growth on changed climate conditions, on the relation­ships between carbon dynamics of forest stands and extreme events, as well as on the influence of forest stand structure on productivity and efficiency.
