The northeast black soil region is an essential ecological zone and a major grain-producing area in China. The continuous reclamation and utilization for many years has aggravated the deterioration of the ecological environment in this region, so it is of great relevance to inquire into the spatial and temporal differentiation characteristics of ecosystem services and synergistic trade-offs in the black soil region for the coordinated socio-economic-ecological development of this region. Taking Bin County as the study area, we quantitatively measured the spatiotemporal patterns and trade-offs and synergistic relationships of three ecosystem services, namely water production, soil conservation and carbon fixation from 2000 to 2020 in the county using the InVEST, RUSLE, CASA model, R language and GeoDA software. The findings indicated that:(1)the temporal variation of water production showed an increasing trend, while carbon fixation and soil conservation showed a tendency to decrease and then increase;(2)the spatial distribution showed that the high value of water production service presented a decreasing trend from the central part to the surrounding area, while carbon fixation and soil conservation services presented a spatial distribution pattern of high in the south and low in the east;(3)the trade-off synergistic relationship showed that the synergistic relationship was the dominant relationship among ecosystem services in Bin County from 2000 to 2020; numerically, the synergistic relationship of the three ecosystem services continued to increase, which was evidenced by the increase of correlation coefficient and Moran's I index; spatially, the positive and negative correlation clustering was obvious; spatially, the positive and negative correlations clustered significantly, and the distribution of trade-off synergistic relationships was spatially divergent. In summary, changes in ecosystem services in Bin County are on an upward trend, with stronger ecosystem services in the southern region, and synergistic development of ecosystem services should be promoted spatially in the future.
