Un article sur la prédiction de l’éclairement relatif en peuplements purs et mélangés vient de paraître dans Forest Ecology and Management. Ce travail a été réalisé sur les placettes expérimentales du dispositif OPTMix. Ci-dessous les points clés de l’article.
Perot, T., A. Mårell, N. Korboulewsky, V. Seigner and P. Balandier (2017). « Modeling and predicting solar radiation transmittance in mixed forests at a within-stand scale from tree species basal area. » Forest Ecology and Management 390: 127-136. doi: 10.1016/j.foreco.2017.01.023
Highlights:
- Radiation under forest canopy was modelled in mono-specific and mixed stands.
- The Beer-Lambert law can be used in mixed stands with the basal area of each species.
- Extinction coefficients were not different between mixed and mono-specific stands.
- Transmittance can be predicted at local scale within a stand with local basal area.
- Predictions of the model are unbiased with a relative mean absolute error of 20%.
