AB  - Grassland is the largest ecosystem type in the Qilian Mountains, accounting for about 50% of the total area of the Qilian Mountains. It provides humans with ecological and cultural habitat, and also provides necessary production materials and living resources. Human occupancy of net primary productivity (HANPP) is a proxy indicator that quantifies the impact of human activities on energy flows in ecosystems. Based on long-term ground observation and remote sensing monitoring data, we used the Century model and the CASA model to estimate the potential net primary productivity (NPP) of the Qilian Mountains grassland and the remaining NPP in the ecosystem respectively, and developed a high-precision spatio-temporal data set of the net primary productivity of human occupation. This dataset contains the HANPP values of natural grasslands in the Qilian Mountains region by grid unit year by year, unit: gC m-2, time range: 2000-2024, spatial range: the entire Qilian Mountains, time scale: year, spatial resolution: 0.0025° × 0.0025° (approximately 250 m × 250 m), naming method: hanpp + year, data format: GeoTIFF. The advantages of this dataset over similar data are the longest time series, the highest spatial resolution and the widest coverage. Against the background of global climate change, simulating the spatio-temporal dynamics of grassland HANPP can quantitatively analyze the response laws of grassland productivity under different ecological restoration scenarios, and has practical guiding significance for optimizing the area and spatial configuration of grassland ecological restoration technologies and projects.
