Abstract

As part of the third phase of the ‘integrated conservation and management of mountain,river,forest,farmland,lake,grassland and desert ecosystems project’,exploring the spatial and temporal changes in ecological environmental quality and the factors influencing it in the Ulansuhai basin plays an important role and has practical significance for ecological environment restoration.Utilizing the MODIS dataset from the Google Earth Engine platform,we developed the Remote Sensing Ecological Index(RSEI)for the Ulansuhai Nur basin for the years 2000,2005,2010,2015,and 2020.Trend analysis and the Hurst Index were then employed to reveal the spatial and temporal changes,and the sustainable change characteristics of the region.1)The annual average RSEI in the Ulansuhai basin shows a fluctuating upward trend,indicating that the vegetation as a whole is in a state of gradual recovery.2)Persistent degradation and ambiguous future trajectories are notable in specific areas of the Ulansuhai Nur basin,underscoring the need for ongoing and focused conservation efforts.3)The quality of the ecological environment in the Dengkou and mine management areas has significantly improved,and the areas of forests and shrublands show an increasing trend.4)The improvement and maintenance of the ecological environment of the Ulansuhai basin still requires long-term monitoring and refined management.The RSEI dataset was constructed through the GEE platform,which enabled the analysis and monitoring of changes in regional ecological and environmental quality,providing references for the management and decision-making in ecological engineering governance and restoration.

Key words： RSEI; spatiotemporal changes; sustainability analysis; Ulansuhai basin area
