Abstract: While Xinjiang has been threatened by rapid climate change in recent decades, the impact of climate change and carbon dioxide increase on the region’s net primary productivity (NPP) remains unclear. Therefore, studying the changes of the ecosystem net primary productivity (NPP) in China’s typical arid areas under the background of climate change is of great significance to the study of desert ecosystems in this region. The study area has a spatial range of 34.3°–49.5°N, 73.5°–96.3°E. Based on the reanalysis meteorological data of MERA, ERA-Interim and CFSR, the study uses the arid ecological model (AEM) simulation to get the NPP distributional data (spatial resolution 50km×50 km) in Xinjiang for 2000–2014. The simulation results are then validated against data from existing literature. This data set can be used as survey data to understand NPP changes in Xinjiang, providing basic data support for the study of arid region ecosystems in northwest China. It also serves the Silk Road Economic Belt and is of great significance for the ecological protection and comprehensive management, economic stability, and sustainable development of arid regions in northwestern China.
