### Changes in MODEL from 2008 to 2018  
Figure 6a illustrates the dynamic changes of the MODEL in Fuyun County during the decade. The variation range of the MODEI in the study area was between \(-\)0.391 and 0.792. Combined with the natural breakpoint method in ArcGIS, the changed values of the MODEI were divided into five intervals: significant decline (\(-\)0.391 to \(-\)0.1), decline (\(-\)0.1 to \(-\)0.015), remained unchanged (\(-\)0.015 to 0.015), increase (0.015 to 0.39), and significant increase (0.39 to 0.792). Based on this, the spatial distribution map of the dynamic change of the MODEI in the study area was obtained (Figure 6b). Table 6 further provided statistics on the detailed changes of pastures in different seasons of the whole region. Statistical analysis showed that the region with improved ecological quality was 7511.42 km\({}^{2}\), accounting for 31.12% of the study area. The significantly improved areas accounted for 0.47% of the whole area. Among them, 4587.03 km\({}^{2}\) was distributed in summer pastures and 2552.33 km\({}^{2}\) and 372.06 km\({}^{2}\) were distributed in spring and autumn pastures and winter pastures, accounting for 19.01%, 10.57%, and 1.54% of the study area, respectively. The area where the MODEI was unchanged was 9788.42 km\({}^{2}\), accounting for 40.56% of the study area, with the largest proportion (Table 6).

Figure 4: LISA aggregation map of MODEI in Fuyun County. Figure 5: LISA significance map of MODEI in Fuyun County. The region where the ecological quality deteriorated was 6838.16 km\({}^{2}\) and accounted for 28.32% of the total area. Within this area, 1307.08 km\({}^{2}\) was distributed in summer pastures and 4225.22 km\({}^{2}\) and 1305.86 km\({}^{2}\) were distributed in spring and autumn pastures and winter pastures, occupying 5.41%, 17.5%, and 5.41% of the study area, respectively (Table 6). The areas where the MODEL declined were mainly located in the high-altitude mountains in the northernmost part of summer pastures and spring and autumn pastures and winter pastures. The places where the MODEL decreased significantly were situated on both sides of the river (Figure 6). \begin{table}
