A meticulous examination of the dynamic patterns in habitat quality (HQ), ecological sensitivity (ES), and net primary production (NPP) is vital to bolster regional ecological integrity and the enduring progress of the socio-economic landscape. This study employs the ES, HQ, and NPP models to delve into the spatial and temporal dynamics, as well as the interplay among these critical environmental indicators. Using principal component analysis, this research identifies and distills the major determinants influencing the synergy among these metrics. A suite of analytical tools, including cellular distribution mapping, fitting correlations, three-dimensional (3D) surface plots, and geographically weighted analysis, were harnessed to elucidate the intensity, range, and temporal flux of the intertwined factors shaping the coordination index. The findings disclose that the zones of high ecological sensitivity within the Yangtze River Economic Belt (YREB) largely coincide with forests and grasslands, whereas the peaks of NPP are found within tropical rainforests, and the highest ratings of habitat quality are prevalent in plateau grasslands. Predominant coordination typologies observed are characterized by High ES paired with Low NPP, and High HQ conjoined with Low NPP. In the nascent stages, social and economic influences markedly sway the coordination index, whereas natural environmental factors exert a sustained impact throughout. By charting the spatial-temporal contours, categorizing coordination types, and decoding the influence mechanisms of HQ, ES, and NPP within the YREB, this research formulates strategic recommendations aimed at nurturing regional ecological security architectures and propelling sustainable socio-economic advancements.
