[Objective]The aims of this study are to clearly understand the trade-offs and synergies within ecosystem services, to ensure the sustained effective supply of ecosystem services, and to achieve the dual objectives of watershed ecological conservation and high-quality development. [Methods]The typical returned farmland area of the Loess Plateau in northern Shaanxi Province was taken as an example. Based on the land-use change data from 1990 to 2020. the InVEST model was utilized to quantify the spatiotemporal characteristics of four key ecosystem services:carbon storage, water yield, soil conservation, and habitat quality. Through correlation analysis, the trade-offs, synergies, and scale characteristics among various ecosystem services were thoroughly investigated. [Results](1)From 1990 to 2020, carbon storage and habitat quality were improved continuously, while water yield and soil conservation showed an overall increasing trend after an initial decrease, with a spatial pattern of lower level in the southeast and higher levle in the northwest.(2)The ecosystem services of the Loess Plateau in northern Shaanxi Province were predominantly synergistic. The synergistic effects had continuously strengthened from 1990 to 2020. Trade-off effects mainly occur between water yield and other ecosystem services, with trade-off regions primarily distributed in the western and northeastern parts of the study area.(3)A spatial scale effect was evident in the trade-offs and synergies among ecosystem services. With increasing spatial scale, the correlation gradually strengthened while the significance decreased, and the directionality of the relationship was changed. [Conclusion]The ecosystem services within the northern Shaanxi Loess Plateau predominantly exhibit synergistic interactions, and these interactions are influenced by spatial scale effects in the trade-offs and synergies among different ecosystem services.
