The identification of ecosystem health and its influencing factors is crucial to sustainable management of ecosystem and ecosystem restoration. In spite of numerous studies on ecosystem health have been carried out in different perspectives, few studies have investigated the spatiotemporal heterogeneity between ecosystem health and its influencing factors systematically. Considering this gap, the spatial relationships between ecosystem health and its factors concerning climate, socioeconomic and natural resource endowment at the county level were estimated based on a geographically weighted regression (GWR) model. The spatio-temporal distribution pattern and driving mechanism of ecosystem health were systematically analyzed. Results showed that:(1)The ecosystem health level in Inner Mongolia spatially increases from northwest to southeast, displaying notable global spatial autocorrelation and local spatial aggregation.(2)The factors influencing ecosystem health exhibit significant spatial heterogeneity. Annual average precipitation (AMP),biodiversity(BI) was positively correlated with ecosystem health, annual average temperature(AMT) and land use intensity(LUI)are estimated to be negative.(3) Annual average precipitation (AMP) significantly improves ecosystem health, whereas annual average temperature (AMT) significantly worsens eco-health in the eastern and northern regions. LUI negatively impacts ecosystem health in western counties (such as Alxa, Ordos, and Baynnur).This study contributes to extending our understanding of ecosystem health depend on spatial scale, and could inform decision-makers about how to control various influencing factors to improve the local ecology under local conditions. Finally, this study also proposed some relevant policy suggestions and provide effective ecosystem preservation and management support in Inner Mongolia.
