Rocky Desertification Classification and Driving Factors in Liupanshui, China (1987–2022)

A study analyzing the spatiotemporal evolution and driving mechanisms of rocky desertification in Liupanshui City, Guizhou Province, China, from 1987 to 2022. The research constructed a Rocky Desertification Index (RDI) based on NDVI and Bare Land Index (BLI) data, achieving an overall classification accuracy of 88.16%. It was authored by Meng Liu and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Modeling spatiotemporal trends in rocky desertification based on the constructed RDI index.
• Identifying dominant driving factors for land degradation based on the reported OPGD analysis of land use, climate, and terrain.
• Analyzing shifts in ecological driving mechanisms over time based on the PLS-SEM results comparing pre-2000 and post-2007 periods.

Strengths

• Achieved a reported overall classification accuracy of 88.16% for rocky desertification degrees.
• Provides analysis over a 35-year time range (1987–2022) for Liupanshui City.
• Identified land use as the dominant driving factor with quantified q-values ranging from 0.44 to 0.64.

Limitations

• The dataset is a 12.2 KB DOCX file, suggesting the primary data may be embedded in a document format rather than a structured data file.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
