| Zusammenfassung |
| Net primary production (NPP) is one of the most important variables in terms of ecosystems
inventory and management, because it quantifies its growth and reflects the impact
of biotic and abiotic factors, which could affect it. Interest in NP has increased
recently because of the increasing interesting in climate change and the need in
understanding its impact on the environment. There are ecophysiologic models, as
Forest-BGC that allow for estimating NPP. The types of models offer a possible
methodology to test these phenomena, beyond temporal and spatial scales, not
available with tradicional inventory methodologies. To analyze the Forest-BGC
performance, NPP data obtained with model were compared with collected data in
the field, in the same sampling plots. For a parameterization and validation of the
FOREST-BGC, this study was carried on based on 500m2 sampling plots from
the National Forest Inventory 2006 and are located in several County Halls of the
district of Vila Real, Portugal (Montalegre, Chaves, Valpaços, Boticas, Vila Pouca
de Aguiar, Murça, Mondim de Basto, Alijó, Sabrosa and Vila Real). In order to
quantify Biomass dinamics, we have selected 45 sampling plots: 19 from Pinus
pinaster stands, 17 from Quercus pyreneica and 10 from mixed of Quercus with Pinus.
Adaptation strategies for climate change impacts can be proposed based on these research
results. |
