Based on monthly data of precipitation, temperature, sunshine duration, wind speed, relative humidity and other climatic factors in Youyang County during 1956-2013, net primary productivity (NPP) in the county was calculated by using a climate productivity model, and effects of changes in climatic factors on NPP in the county were studied. The results show that annual average NPP in Youyang County during 1956-2013 was 11.137 t/(hm
2 · a), but there were no significant changes over the past 58 years. There was a significantly positive correlation between NPP and annual precipitation or annual mean relative humidity. Under the background of global warming, NPP in Youyang County will face greater pressure, thereby putting pressure on local ecological environment. The research can provide scientific reference for the construction of Youyang County and ecological protection zones in the southeast of Chongqing. [ABSTRACT FROM AUTHOR]- Published
