Spatial and temporal patterns of vegetation carbon sources/sinks and driving factors in southeastern Xizang from 2000 to 2020.

ABSTRACT: Net ecosystem productivity (NEP) is a crucial measurement for understanding ecosystem function and carbon cycling. On the basis of Moderate Resolution Imaging Spectroradiometer (MODIS) data, meteorological data, and topographic data, combined with the enhanced Carnegie Ames Stanford Approach (CASA) model, we analyzed the spatiotemporal trends and changes in the vegetation NEP in southeastern Xizang from 2000 to 2020. Additionally, we employed the GeoDetector model to identify the driving factors influencing the vegetation NEP. The results indicated that: (1) from 2000 to 2020, the annual vegetation NEP in southeastern Xizang exhibited a fluctuating increasing trend. The multiyear average vegetation NEP was 519.06 gC m^-2 a^-1, ranging from 11.23 to 1,333.40 gC m^-2<
