In order to explore the zoning effect of ecosystem service value(ESV)under the modifiable areal unit problem(MAUP), taking the Sichuan-Yunnan Ecological barrier as the research object, based on the data of land use in 2018, we used three different scale types and 9 level evaluation units including grid, administrative region and river basin, the method of spatial autocorrelation analysis, geographic detector to examine the ESV multi-scale space differentiation characteristics, and to explore the factor detection and geographic detector response under MAUP. The results indicate that the ESV of the Sichuan-Yunnan Ecological Barrier was 794.581 billion yuan in 2018, with woodland and grassland contributing the most; the spatial distribution of ESV had obvious partitioning effect at different scales, showing the spatial differentiation characteristics of large inter-class differences and small intra-class differences in the scale of evaluation units; at the same time, the spatial agglomeration effect and the spatial distribution of cold and hot spots were significantly different with the different sizes of the evaluation units; through comparative analysis, the grid scale and administrative district scale were combined and analyzed, which could be used as a scale reference for the comprehensive evaluation of ESV for comprehensive evaluation of ESV in large-scale ecological barrier areas; the interaction and synergistic enhancement effects of natural factors and social and economic factors jointly affected the ESV differentiation effect of the Sichuan-Yunnan ecological barrier. In conclusion, the different division of evaluation units will affect the accuracy of evaluation results, and multi-scale evaluation with specific research needs becomes a prerequisite for future scientific quantification of ESV.
