Abstract

This study utilized Landsat 8, Sentinel-2, and ALOS-2 satellite imagery combined with field survey data from 66 sample plots to develop a biomass estimation model and create a biomass map for the Tuyen Lam Lake area in Da Lat City, Lam Dong Province. The study has developed and selected the optimal model for estimating biomass and creating a biomass map of pine forests in the study area by integrating parameters from ALOS-2 and Sentinel-2 satellites with an R² value of 0.79. These results will be useful in the management and sustainable development of forests in the research area. In addition, the study will also contribute to supplementing an important scientific basis in monitoring and managing greenhouse gas emissions and absorption from forests, contributing to Vietnam's common efforts in mitigating and adapting to current climate change.
