Validation of a tree-based forest ecosystem model for simulating Carbon and Nitrogen cycles
Abstract
The overall objective of the proposed study is the validation of simulated C- and N-cycling within the spatially explicit climate-sensitive forest ecosystem model PICUS v1.41 by means of longterm data on tree growth, C and N cycling from permanent research plots of the BFW. PICUS v1.41 recently has been extended with the biogeochemical soil module of the TRACE ecosystem model (Currie et al. 1999) to allow for the simulation of C and N cycling within mixed species stands. In the proposed study permanent research plot data of fertilizer trials installed and monitored over time periods of up to 35 years will be used to evaluate the ability of PICUS v1.41 to correctly simulate longterm C and N pools in forest ecosystems. The study will produce a tested and thus credible climate sensitive ecosystem model that can be applied to study concepts for sustainable management in evenaged and unevenaged mixed species stands.
