Quantifying human activity intensity in the Qinling‐Daba Mountains

People and Nature, Volume 6, Issue 4, Page 1486-1501, August 2024.
Abstract Human activities profoundly impact the Earth system such as climate change, biodiversity, disease transmission. Accurately acquiring and assessing the human activity intensity (HAI) is crucial to exploring human‐nature relationships. However, the mismatch of geospatial data products between humans and natural environmental factors is a data ...

Classification of nighttime light types in China’s nature protected areas based on SDGSAT-1

International Journal of Digital Earth
Protected areas play a crucial role in preserving biodiversity and providing ecosystem services. However, the encroachment of nighttime light increasingly exacerbates light pollution in these regions. Previous studies using remote sensing to assess light pollution in protected areas have primarily relied on single-band Nighttime Light (NTL) imagery ...
