Abstract:
Implementing the ecological restoration by giving priority to planting trees in the eroded area, it is expected to increase the carbon sink of forests. This paper studies the dynamics of Pinus massoniana forest carbon storage of Hetian basin in Changting County of Fujian Province, southeastern China. As Pinus massoniana is the main species used in the ecological restoration, we carried out field surveys with 31 sampling sites in November 2011 to acquire basic data of Pinus massoniana forest in the study area. The regression analysis between the filed-acquired data and the modified normalized difference vegetation index (MNDVI) data derived from a near-synchronised SPOT5 image was performed in order to develop a model to estimate the carbon storage of Pinus massoniana forest in the Hetian basin area. The obtained 2011 model was then calibrated using pseudo-invariant feature (PIF) method to allow the model to be used for estimating the carbon storage of Pinus massoniana forest in 2004 and 2009. As a result, the spatial and temporal dynamics of carbon storage of Pinus massoniana forest in the Hetian basin during 2004 and 2011 were revealed. The results indicate a gradual increase in the carbon storage and carbon density of Pinus massoniana forest in the Hetian basin area in the study period. The carbon storage grew from 9.28×105 t in 2004 to 12.49×105 t in 2011, accompanied by an increase in carbon density from 27.31×10-4 t/m2 to 35.84×10-4 t/m2 during the period. This suggests a significant increase of the carbon sink of Pinus massoniana forest in the area, particularly in the last two years from 2009 to 2011.
