Short summary
We present a 1 km annual dataset of forest cover and nine plant functional types (PFTs) for China, spanning 1981–2023. By integrating multi-source remote sensing imagery with National Forest Inventory data, this dataset reveals spatiotemporal dynamics consistent with China's massive afforestation and ecological restoration initiatives. It serves as a critical tool for clarifying the impacts of forest cover change on the regional terrestrial carbon balance.
