A Novel Method for Estimating Biomass and Carbon Sequestration in Tropical Rainforest Areas Based on Remote Sensing Imagery: A Case Study in the Kon Ha Nung Plateau, Vietnam

Forest ecosystems play a key role in sustaining life on this planet, given their functions carbon storage, oxygen production, and the water cycle. To date, calculations of biomass absorption capacity forest ecosystems—especially tropical rainforests—have been quite limited, especially Vietnam. By applying remote sensing materials, geographic information systems (GIS) facilitate synchronized estimation both ability to absorb over large spatial ranges. In study, we calculated rainforest vegetation Kon Ha Nung Plateau, Vietnam, according four regression models based Sentinel-2 satellite image data, reserve maps, survey standard cell data (including 19 cells for 2016 44 2021). The results comparison computing (log-log, log-lin, lin-log, lin-lin) demonstrated that with highest accuracy were lin-log model (with correlation coefficient R2 = 0.76) 2021 0.765). Based analytical selection models, maps developed Plateau area, 2021, predominant value 80–180 tons/ha (Mg/ha); furthermore, fluctuations analyzed period 2016–2021. Accordingly, CO2 equivalents research area was estimated values. summary, present method estimating via basic linear areas data. This can serve as basis managers calculate synchronize payment services, which contributes promoting livelihoods local people.
