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

Liupanshui City, Guizhou Province, China, is the study area for this dataset on rocky desertification. It contains a two-dimensional Rocky Desertification Index (RDI) derived from NDVI and BLI satellite data, with an overall classification accuracy of 88.16%. The data was created by Meng Liu and published on figshare in 2026 to analyze spatiotemporal evolution and driving factors.

Use Cases

• Analyzing spatiotemporal trends in rocky desertification based on the RDI index from 1987 to 2022.
• Identifying dominant driving factors for land degradation based on the reported OPGD analysis results.
• Modeling the shift from natural to human-activity dominated driving mechanisms using the PLS-SEM results.
• Assessing the effectiveness of ecological restoration policies in karst regions based on reported alleviation trends.

Strengths

• Overall classification accuracy for rocky desertification degrees is reported as 88.16%.
• Analysis covers a 35-year time series from 1987 to 2022.
• Driving factor analysis includes quantified q-values (0.44 to 0.64) for land use.

Limitations

• Dataset scale is limited to 12.2 KB, suggesting it may contain summary statistics or a small sample rather than raw observations.
• 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.
