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 two-dimensional Rocky Desertification Index (RDI) based on NDVI and BLI, achieving an overall classification accuracy of 88.16%. It was authored by Meng Liu and published on figshare in 2026.

Use Cases

• Modeling spatiotemporal trends in rocky desertification based on the constructed RDI index.
• Identifying dominant environmental drivers using the Optimal Parameter-based Geographical Detector (OPGD) analysis mentioned.
• Analyzing shifts in driving mechanisms from natural to human factors using Partial Least Squares Structural Equation Modeling (PLS-SEM).
• Supporting ecological restoration planning in karst regions based on the analysis of land use and climatic interactions.

Strengths

• The study reports a high overall classification accuracy of 88.16% for its rocky desertification model.
• Analysis covers a long temporal span of 35 years (1987–2022).
• The methodology is explicitly described, including the use of RDI, OPGD, and PLS-SEM.

Limitations

• The dataset is very small (12.2 KB), suggesting it likely contains summary results or a document rather than raw observational data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative modeling.
