Net primary productivity (NPP) of terrestrial ecosystems serves as a crucial carbon sink, playing significant role in mitigating climate change. This study, focusing on the Yangtze River Economic Belt (YREB), key area for both economic development and ecological conservation China, evaluates temporal spatial changes regional NPP its responses to climatic factors against backdrop global Utilizing long-term meteorological grid data from 1981 2017, we analyzed annual change patterns linear nonlinear using copula functions. Our findings indicate that 57.00 % YREB has experienced increase NPP, with most substantial decreases observed Shanghai surrounding areas (P < 0.05). Temperature emerged driver, positively correlating over half study Moreover, response temperature precipitation underscores complex interactions between these factors, revealing sensitivity variations surpasses precipitation. The also highlights influence solar radiation topographic positive correlation 15.85 practical significance lies their implications management resilience strategies. potential targeted optimize sequestration across YREB. Furthermore, identified topography influencing offer valuable insights formulation adaptive strategies enhance ecosystem contribute achieving neutrality goals. By elucidating dynamics range environmental this provides foundation informed decision-making mitigation efforts within similar regions globally.
