英文摘要	Ecosystem monitoring provides us with valuable information for modeling the future response to global changes and designing management plans. This paper clarifies the ability of ecosystem indices to monitor ecosystem degradation and restoration. The indices include the changes in landscape metrics, water birds' habitat, changes in the extent of the affected areas by sand and dust storms, and availability of water. The land-use/land-cover maps of 1977, 2000, 2015, and 2020 were created using the support vector machine classification method and were utilized as inputs to calculate ecological indices. The results of this study revealed advantages of landscape indices to monitor the ecosystem. Landscape metrics are measurable units allowing the quantification of spatial pattern change. The land-use/land-cover maps of 1977, 2000, 2015, and 2020 were created using the support vector machine classification method and were utilized as inputs to calculate ecological indices. The results show that in 2000 the ecosystem was in worse condition. In this year, the bare land area increased by 496% rather than in 1977. But, in 2020 the water body and flooded vegetation increased by 100% and vegetation raised up by 67%; also, the bare land decreased by 47%. Therefore, the ecosystem restored in 2020 in comparison with 2000, while in comparison with 1977 the ecosystem is degraded in 2020 because the water body and flooded vegetation declined by 40 and 67%. Also, the bare land area in 2020 is 215% higher than in 1977. Habitat suitability maps are valuable for designing conservation action plans for critical species. Sand and dust storms are a particular index for monitoring the ecosystem condition in an arid area. The change in water availability is a valuable index for monitoring ecosystem degradation and restoration. Based on these results, a combination of these indices provides a comprehensive tool for monitoring the ecosystem because each index quantifies the change in a particular criterion of the ecosystem.
