Overview

Analysis reveals spatial heterogeneity in desertification trends in semi-arid regions, indicating key factors for ecological management.

Key Points

  • This research aims to clarify the dynamics of desertification in the Xiliao River Basin for ecological restoration.
  • Reconstructed Desertification Difference Index (DDI) from Landsat imagery at 5-year intervals (1985-2025).
  • Utilized an XGBoost model with SHAP analysis to understand the contributions of various factors.
  • Incorporated 15 natural and socio-economic indicators into the analysis.
  • Desertification intensified from 1985 to 2000, with an annual degradation rate of 2.74%.
  • From 2001 to 2025, recovery surpassed degradation at an annual rate of 3.01%.
  • Strong spatial heterogeneity observed, with degradation mainly in Horqin Sandy Land and recoveries in Chifeng and Tongliao.
