Rocky Desertification Index and Driving Factors for Liupanshui, China (1987–2022)

Meng Liu's dataset contains a classification of rocky desertification degrees and an analysis of driving factors for Liupanshui City, Guizhou Province, China, spanning 1987 to 2022. It is based on a two-dimensional Rocky Desertification Index (RDI) constructed from Normalized Difference Vegetation Index (NDVI) and Bare Land Index (BLI) data. The dataset was last updated on 2026-05-22 and is shared under a CC-BY-4.0 license.

Use Cases

• Analyzing spatiotemporal trends in rocky desertification based on the RDI classification.
• Identifying dominant environmental drivers using the Optimal Parameter-based Geographical Detector (OPGD) analysis results.
• Modeling shifts in driving mechanisms from natural to human factors using Partial Least Squares Structural Equation Modeling (PLS-SEM) outputs.
• Supporting ecological restoration planning based on the quantified impact of land use and its interactions with climate and terrain.

Strengths

• Overall classification accuracy for rocky desertification reached 88.16%.
• Covers a 35-year time series from 1987 to 2022.
• Identifies land use as the dominant driving factor with q-values ranging from 0.44 to 0.64.

Limitations

• The dataset is very small at 12.2 KB, suggesting limited raw data or a summary document.
• 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.
