| Zusammenfassung |
| In the last several years, the interest in forest biomass and carbon stock estimation has
increased due to its importance for forest management, modelling carbon cycle, and other
ecosystem services. However, no estimates of biomass and carbon stocks of deferent forest
cover types exist throughout in the Xuan Lien Nature Reserve, Thanh Hoa, Viet Nam. This
study investigates the relationship between above ground carbon stock and different
vegetation indices and to identify the most likely vegetation index that best correlate with
forest carbon stock. The terrestrial inventory data come from 380 sample plots that were
randomly sampled. Individual tree parameters such as DBH and tree height were collected to
calculate the above ground volume, biomass and carbon for different forest types. The
SPOT6 2013 satellite data was used in the study to obtain five vegetation indices
NDVI, RDVI, MSR, RVI, and EVI. The relationships between the forest carbon
stock and vegetation indices were investigated using a multiple linear regression
analysis. R-square, RMSE values and cross-validation were used to measure the
strength and validate the performance of the models. The methodology presented here
demonstrates the possibility of estimating forest volume, biomass and carbon stock. It can
also be further improved by addressing more spectral bands data and/or elevation. |
