Ecosystem services (ESs), as important indicators for ecosystem conditions, are always interacted complexly, however, the underlying mechanisms remain not fully understood. The Beijing-Tianjin-Hebei (BTH) region is a typical example of this complexity and is one of the most populous regions globally. In this study, we take the BTH region as the study area and try to identify the spatiotemporally complex relationships and dominant drivers of ESs, by utilizing multiple methods: Pearson correlation analysis, partial correlation analysis and the GeoDetector method. Three critically important ESs: soil erosion, water yield, and net primary production (NPP) are simulated for the period of 2000 to 2018. The results show that the Pearson correlation coefficient indicated a synergistic relationship between soil erosion and water yield and between water yield and NPP and a trade-off relationship between soil erosion and NPP, while the partial correlation analysis using the normalized difference vegetation index (NDVI) and precipitation as controlling factors showed that the relationships between soil erosion and water yield and between water yield and NPP were transformed to trade-offs. We confirmed that the drivers (especially the shared drivers and dominant drivers of each ecosystem service) played important roles in the direction of complex relationships; when different factors were involved in the relationships, the direction of positive or negative relationships may be diverse.
