Net primary productivity (NPP) is a critical component in terrestrial ecosystem carbon cycles. Thus, quantitatively estimating and monitoring the dynamics of NPP have become key aspects for exploring cycle ecosystems. Anthropogenic activity, such as urbanization, has significant effects on increases pressure natural resources specific region. However, to date, although many studies focused relationship between variation they usually ignored any differences at long-term spatiotemporal urbanization factors, which led insufficient understanding urbanization-induced impacts NPP. As result, this study effectively explored from 2001 2012 its corresponding with taking Hubei Province China case area. To clarify degree spatial distribution temporal population gross domestic product (GDP) were simulated based elevation-adjusted human settlement index nighttime lights data. The major results showed that high areas located those highlands widespread woodland, value continued grow during period. low mainly distributed urban areas, had visible loss. GDP both strong correlation negative was concentrated center Hubei, dense developed economy. In order further realize their complex relationship, coefficients annual two factors calculated, changing trends investigated. Overall, findings may provide reference interaction ecological environment socioeconomic processes under background global rapid urbanization.
