内容記述 | Site-based measurements of biomass (and carbon) are the accurate method but costly in time, budget and manpower. The application of remotely sensed data may achieve our goals in a large area in the shortest time. We investigated how remotely-sensed data could be applied to estimate above-ground biomass in the production forests of Deramakot Forest Reserve (reduced-impact logging site) and Tangkulap Forest Reserve (conventional logging site as of the analysis). We converted the tree census data from the research plots, which had been established by 2003, into above-ground biomass with the use of standard allometric equations. Altogether, we employed the data from 51 plots. We accurately measured the four corners of each plot with a GPS (Global Positioning System) equipment. We added three plots devoid of any tree cover as reference points. Subsequently, the location of each plot was determined on the LANDSAT ETM data taken in 2002. Among various combinations of LANDSAT bands, the normalized index of band 4 and 5 (called NDS!) demonstrated the highest correlation with the biomass values estimated from the ground data. However, the biomass estimates from this correlation model saturated at biomass 500 ton/ha or greater. This causes a considerable underestimate of biomass in high stock forests. We therefore numerically corrected the biomass values, where reflectance signals were saturated, using the canopy heterogeneity as guidance; in this algorithm we added proportionately greater correction values, with increasing canopy homogeneity, to the biomass values estimated from the correlation model. Application of this method to Deramakot and Tangkulap yielded the mean biomass density of 347 ton/ha in Deramakot, and 293 ton/ha in Tangkulap. These values were comparable to the mean values obtained from the ground survey, suggesting the adequacy of our methods. The difference of the two mean values (54 tonlha) can be attributed to the difference in the logging methods. The cautious use of our methods can legitimately evaluate the above-ground biomass (and carbon) in a large area in the mixed dipterocarp tropical rain forests of this region. | |||||
