Simulation of Soil Organic Carbon Content Based on Laboratory Spectrum in the Three-Rivers Source Region of China

open access: yesRemote Sensing, 2022
Soil organic carbon (SOC) changes affect the land carbon cycle and are also closely related to climate change. Visible-near infrared spectroscopy (Vis-NIRS) has proven to be an effective tool in predicting soil properties.

Ecosystem service delivery in Karst landscapes: anthropogenic perturbation and recovery [PDF]

open access: yesActa Geochimica, 2017
Couvrant de vastes régions de la Chine, les paysages karstiques sont exceptionnels car un changement rapide et intensif de l'utilisation des terres n'a provoqué une grave dégradation de l'écosystème qu'au cours des 50 dernières années. L'intensification de la production alimentaire par l'agriculture au XXe siècle a entraîné une détérioration rapide de ...

The spatiotemporal pattern and influencing factors of land surface temperature change in China from 2003 to 2019

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Land surface temperature (LST) is an essential parameter in land–atmosphere interaction. However, it is still poorly understood about the effects of seasonal LST on the interannual LST change and the dominant driving force for the variation in LST.
