China County Agricultural and Geographic Data for 1990

1990 county-level datasets from China compiled for the DNDC biogeochemistry model. The collection includes seven thematic datasets on agricultural management, crops, nitrogen deposition, geography, population, land use, livestock, and soil properties. The data was aggregated by SCIOPS from multiple Chinese sources for use at the University of New Hampshire.

Use Cases

• Calibrate the DNDC model's soil carbon predictions using county-level soil properties data.
• Analyze the relationship between agricultural management practices and crop yields across Chinese counties.
• Estimate nitrogen deposition impacts on county-level land use and livestock distributions.
• Study geographic and population factors influencing 1990s agricultural land use patterns.

Strengths

• Seven distinct thematic datasets provide a multi-faceted view of county conditions.
• Data is standardized at the county scale for consistent spatial analysis across China.
• Compiled for a specific, validated scientific model (DNDC), suggesting structured relevance.

Limitations

• Data is from a single year (1990) and is temporally stale for contemporary analysis.
• The exact number of rows, columns, and file size is unknown, hindering technical assessment.
• Specific data sources and compilation methodology within China are not detailed.
