Severe Water Erosion Regions in China from 2000 to 2020

A 6.4 MB dataset by Hongna Wang estimates water erosion in China from 2000 to 2020 using the Chinese Soil Loss Equation (CSLE). It identifies severe erosion regions and their drivers, showing the center of gravity of erosion area migrated southwestward during this period. The data reclassifies China into four severe and two slight water erosion subregions.

Use Cases

• Analyze spatial patterns of severe water erosion based on the classification into four severe subregions
• Model the influence of natural and human drivers on erosion processes based on described factors like steep terrain and agricultural activity
• Track temporal dynamics of erosion from 2000 to 2020 based on the estimated time series
• Support national soil and water conservation efforts by identifying regions concentrated along the Hu Line

Strengths

• Covers a 21-year time range from 2000 to 2020
• 6.4 MB file size suggests a detailed but manageable dataset
• Uses the established Chinese Soil Loss Equation (CSLE) for estimation
• Provides a geographic reclassification of China into erosion subregions

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic or methodological bias inherent to the CSLE model and source platform
