Abstract

Strengthening ecosystem monitoring and improving the efficiency of ecological risk assessment are of great significance for the sustainable development of ecosystems in an arid area. Using remote sensing monitoring data of land use, the ecological risk status of typical arid areas is assessed, its spatial heterogeneity is analyzed from the perspective of space-time, and the key areas of ecological risk management are finally identified. The results show that (1) the transformation mode of landscape ecological risk was dominated by medium–low risk to medium risk, and low risk to medium–low risk as a secondary level; in addition, the ecological risk level of the region increased. From 2000 to 2020, the transformation mode of landscape ecological risk was dominated by medium risk to medium–low risk, and medium–low risk to low risk as a secondary level; in addition, the regional ecological risk level shows a moderating trend. (2) The spatial difference in the ecological risk level in the Hexi region is obvious, showing a gradual decline from east to west, and the spatial difference in the ecological risk level in the west is significant. (3) A total of 1194 grid units are identified as key areas for ecological risk management in the Hexi region, accounting for 43% of the study area. This study provides important theoretical basis for ecosystem monitoring and risk assessment management in similar areas of arid regions.
