Digital Atlas of the Current Spatial Distribution of Natural Health Indicators in Black Soils

It includes soil biodiversity indicators—such as bacterial, protistan, and fungal richness—as well as soil bulk density, clay content, sand content, electrical conductivity, field capacity, pH, soil organic carbon, microbial biomass carbon, soil respiration rate, microbial metabolic quotient, and an integrated soil health score.

Using standardized thematic maps and graduated color schemes, the atlas visualizes regional variation and spatial heterogeneity in black soil health. It provides baseline information and scientific support for soil health assessment, degradation-risk identification, conservation zoning, sustainable black soil management, and cultivated-land quality improvement.
