China Cultivated Land Quality and Productivity Raster Layers

Xiaolong Wang published three GeoTIFF raster layers on March 14, 2026, totaling 146.9 MB. The dataset contains spatial distributions for low- and medium-yield croplands, cultivated land quality grades, and improvement zones. It supports research on agricultural land management and sustainability in China.

Use Cases

• Analyze spatial correlation between the cultivated land quality grade map (CLQ) and the low- and medium-yield field (MLY) layer to identify degradation drivers.
• Use the improving zone map to prioritize land management interventions based on CLQ and MLY classifications.
• Model Net Primary Production (NPP) relationships with CLQ grades to assess agricultural productivity.
• Integrate MLY, CLQ, and improving zone rasters for regional agricultural sustainability planning.

Strengths

• Contains three distinct, thematically linked raster layers (MLY, CLQ, improving zone) for integrated analysis.
• Dataset size of 146.9 MB indicates medium spatial resolution and coverage for China.
• Published under a permissive CC BY 4.0 license, facilitating reuse and sharing.

Limitations

• Unknown row/column count and specific spatial resolution limits quantitative assessment of detail.
• Data is static; temporal coverage and update frequency are not specified, limiting trend analysis.
