　　Net primary productivity (NPP) is one of the key ecosystem services provided in the Lower Heihe River Basin (LH RB),an important ecological function zone in the arid region of northwest China which is very sensitive to climate change and human activities due to serious water scarcity.This study analyzed the long time-series variations of NPP in the LHRB during 2001-2010 and explored the impacts of climate change and human activities on NPP.NPP was first estimated with the C-fix model,and then scenario analysis was carried out to spatially explicitly investigate the impacts of climate change and human activities on NPP during 2001-2010.Results suggested N PP ranged between 0-448.70 gC/(m2·a),showing obvious spatial heterogeneity.
