Tracking of Vegetation Carbon Dynamics from 2001 to 2016 by MODIS GPP in HKH Region

Abstract

Carbon dynamics, a key index to evaluate ecosystems, are very complex in the Hindu Kush Himalayan (HKH) region due to the topography, diverse regional climate, and different land cover types. MODIS GPP was used to evaluate carbon sequestration in the HKH region from 2001 to 2016. In general, the spatio-temporal variation of the average daily gross primary productivity (GPP) was very heterogeneous due to the changing terrain, diverse regional climate, and different land cover types in the region. Many factors should be considered for GPP measurements, including satellite, airplane, ground-based and modelling data. We concluded that it is necessary to determine the driving forces of GPP in the future in order to establish scientific policies and development programs for the HKH region.
