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

An 88.16% accurate classification of rocky desertification degrees for Liupanshui City, China, spanning 35 years from 1987 to 2022. The dataset was created by Meng Liu using a two-dimensional Rocky Desertification Index derived from NDVI and BLI. It shows an overall alleviation trend, with non-desertified areas expanding and moderate/intensive desertification decreasing.

Use Cases

• Analyzing spatiotemporal evolution of rocky desertification based on the 35-year time series.
• Identifying dominant driving factors for land degradation based on the OPGD analysis of land use, climate, and terrain.
• Modeling shifts in ecological driving mechanisms based on the PLS-SEM results showing a transition from natural to human-activity dominance.
• Evaluating the effectiveness of ecological restoration policies based on the documented alleviation trend.

Strengths

• Classification accuracy of 88.16% for rocky desertification degrees.
• Covers a 35-year time series from 1987 to 2022.
• Analysis identifies land use as the dominant driving factor with q-values ranging from 0.44 to 0.64.

Limitations

• 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.
