Abstract: Remote sensing-derived LUC maps for 2009, GIS-based LUC change model, and ecosystem service value of NPP were used to facilitate the analysis. The results forests have significantly higher NPP values than farmlands, whose NPP is approximately equal to that of brushlands. The scenario-based LUC change analysis revealed that if the urban LUC change pattern continues, the total ecosystem service value of NPP will also change, especially if the forest cover is not fully protected and conserved. Our results highlighted that under the great pressure of urbanisation, there is a need to strengthen the proper implementation of policies in order to maintain and improve ecosystem services. Although there are limitations to the estimated ecosystem service value of NPP of Yan'an to be taken into account in future studies, the magnitude of the estimated changes in the LUC is substantial.
