Abstract

This study examines the spatiotemporal distribution and change characteristics of forest and grassland vegetation cover in Sanmenxia City from 1990 to 2020, predicting the future trend of forest and grassland vegetation cover to provide a reference for the establishment of a reference system for ecological restoration in bauxite mining in Sanmenxia City. Utilizing NDVI time series data from 1990 to 2020, the study employs annual mean, Theil-Sen median trend analysis, and Mann-Kendall test methods to investigate the spatiotemporal distribution characteristics of forest and grassland vegetation cover in Sanmenxia City. The Hurst index is used for predicting the future changes in vegetation cover in the area. Overall, the vegetation cover in Sanmenxia City mainly shows a pattern of being higher in the south and lower in the north, with the area of vegetation cover improvement significantly exceeding the area of degradation from 1990 to 2020. The future outlook for vegetation cover in Sanmenxia City is promising, with areas predicted to have positive development trends exceeding those with negative trends. Regions with negative trends are primarily located in the central and northern parts of Sanmenxia City along the Yellow River, expected to shift from improvement to degradation trends. This calls for significant attention in ecological protection and management processes.
