Ecosystem Function Maps for Xinjiang Drylands, 2000-2024

Multi-year geospatial maps of ecosystem functions in Xinjiang, China, produced by Dechao Zhai and published in 2026. The maps classify water retention, sandstorm prevention, and agricultural production regions using a random forest model and Landsat imagery from 2000 to 2024. They reveal transition trajectories driven by climate variability and agricultural expansion.

Use Cases

• Analyzing spatial patterns of water retention, sandstorm prevention, and agricultural production based on the described ecosystem function classification.
• Modeling the correlation between ecosystem transitions and precipitation changes based on the reported R values.
• Evaluating the impact of policy-driven cropland expansion on desert landscapes based on the identified 'DS-AP' transition pathway.
• Mapping long-term ecosystem function transitions across a dryland region based on the 24-year temporal coverage.

Strengths

• High classification accuracy reported between 0.864 and 0.882.
• Long temporal coverage spanning 24 years from 2000 to 2024.
• Analysis covers the entire Xinjiang region, a vast and typical dryland area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document, which may contain processed results rather than raw geospatial data.
