Short summary
We developed OasisMap30, a 30 m annual land-cover dataset for Chinese oases covering 1987–2024, with an overall accuracy exceeding 90 %. The dataset reveals a 45.87 % expansion of Chinese oases, mainly driven by cropland expansion and grassland restoration. The consistent, high-resolution OasisMap30 dataset provides a valuable basis for investigating oasis landscape dynamics, socio-ecological responses, and sustainable development in dryland regions.
