## 5 Conclusions  
This paper used MODIS data to extract the GPP, FVC, LAI, LST, and WET information, and a MODEL model was established to analyze and evaluate the ecological environmental quality of Fuyun County and the spatial differentiation characteristics of MODEL were discussed. The research found that: (1) FVC, GPP, LAI, and WET had a positive impact on the MODEL, while LST negatively impacted the MODEL; among them, FVC and GPP had a more significant effect on the quality of the ecological environment. (2) The average values of the MODEL in the study area in 2008 and 2018 were 0.292 and 0.303, respectively,

indicating that the MODEI in the study area was developing towards a better trend. The MODEL in Fuyun County showed a spatial pattern of \"excellent in the north and poor in the south\". The areas of poor and bad levels accounted for 67.15% and 65.60% of the total area in 2008 and 2018, respectively. The areas of a moderate level accounted for 13.85% and 11.58% of the total area in 2008 and 2018, respectively. In 2008 and 2018, the areas of the good and high levels of MODEI accounted for 19% and 22.82% of the study area in 2008 and 2018, respectively. The values of Moran's I were high in both periods, which indicated that the spatial distribution was clustered rather than random. (3) The improvement of the ecological conditions in the study area was mainly driven by the increase in precipitation. The areas where the MODEI increased were mainly located in the summer pastures, which was ascribed to the decrease in the GPI and increased precipitation in the summer pastures. The areas where the MODEI increased significantly were located along the river, which was mainly caused by the planting of artificial grassland along the river. The areas where the MODEL was basically unchanged were primarily distributed in spring and autumn pastures and winter pastures. The areas where the MODEI decreased were mainly distributed in the northern part of summer pastures situated in high-altitude mountains, and the spring and autumn pastures and winter pastures, and the areas where the MODEI decreased significantly were mainly located on both sides of the rivers. To a certain extent, the increase in the GPI could explain the deterioration of the ecological quality of the spring and autumn pastures and winter pastures. In addition, due to the expansion of urban and rural residential land, the ecological quality of some areas on both sides of the river has seriously deteriorated. In view of the deterioration of the ecological quality of spring and autumn pastures and winter pastures, measures need to be taken to reduce the intensity of grazing. Firstly, the local government can continue to implement the herdsmen settlement project and increase the diversity of herdsmen's livelihoods, and the intensity of grassland grazing can be reduced through captive breeding and corresponding infrastructure. Secondly, it is necessary to carry out the planting of stable and high-yield, high-quality forage grass. Combined with the natural conditions of the study area, large-scale construction and planting of high-quality and high-yield artificial forage grass should be carried out along the Irtysh River near the spring and autumn pasture and the Ulungur River near the winter pasture to provide stable and sufficient forage for livestock and achieve the purpose of using a small area of high-quality and high-yielding artificial grassland in exchange for the protection and restoration of a large area of natural grassland. Planting artificial grassland can solve the problem of extended use time of spring and autumn pastures and the wide difference between the grassland area and the carrying capacity of winter pastures, and reduce the pressure on the grasslands. These suggestions can provide a scientific basis for ecological restoration and ecological quality improvement of mountain-basin systems in arid areas and other similar ecosystems throughout the world.
