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

Liupanshui City in Guizhou Province, China, is the focus of this dataset analyzing rocky desertification from 1987 to 2022. It contains a classification of rocky desertification degrees and an analysis of driving factors using a constructed Rocky Desertification Index (RDI). The dataset was authored by Meng Liu and shared under a CC-BY-4.0 license.

Use Cases

• Analyzing spatiotemporal trends in rocky desertification based on the Normalized Difference Vegetation Index (NDVI) and Bare Land Index (BLI).
• Identifying dominant driving factors for land degradation using the Optimal Parameter-based Geographical Detector (OPGD) analysis mentioned.
• Modeling shifts in ecological driving mechanisms over time with Partial Least Squares Structural Equation Modeling (PLS-SEM).
• Supporting policy for ecological restoration by assessing the impact of land use and climate factors.

Strengths

• Classification accuracy for rocky desertification degrees is reported at 88.16%.
• Analysis covers a 35-year time span from 1987 to 2022.
• Dataset is openly shared under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (12.2 KB), suggesting it may contain summary statistics or a limited sample rather than raw observational data.
