Response of the Normalized Difference Vegetation Index (Ndvi) to Snow Cover Changes on the Qinghai-Tibet Plateau

open access: yesRemote Sensing, 2023
The eco-hydrological process related to vegetation on the Qinghai–Tibet Plateau is special, and the impact of snow cover on the growth of vegetation is unique and important. In this study, we analyzed the multi-year variations in the normalized difference vegetation index (NDVI) and snow cover on the Qinghai–Tibet Plateau from spatial and temporal ...

STUDY OF THE POTENTIAL OF CO2 ABSORPTION BY VEGETATION BASED ON NORMALIZED DIFFERENCE VEGETATION INDEX (NDVI) VALUE

open access: yesKonversi, 2021
Abstrak: Peningkatan gas rumah kaca (GRK) sebagai salah satu penyebab perubahan iklim. Salah satu gas yang berperan pada GRK adalah karbon dioksida (CO2). Kandungan CO2 di atmosfer diduga meningkat sekitar 0.03-0.06% dan menyebabkan kenaikan suhu sebesar 4.25°F (Fardiaz 1992). Hutan berperan dalam upaya peningkatan penyerapan CO2.
