  <dc:title>Fine-scale Soil Quality Type Map of the Black Soil Region (2021)</dc:title>

  <dc:description>This dataset is an evaluation index system constructed based on the Pressure-State-Response (PSR) framework model, following an in-depth study of the current status of cultivated land resources and their key influencing factors in the Northeast Black Soil Region of China. The data cover multiple key parameters within this region, including slope, land degradation index, vegetation growth status, soil organic matter content (at 10 m spatial resolution), soil total nitrogen content (10 m resolution), soil sand content (10 m resolution), mean annual precipitation, and mean annual temperature. Based on these indicators, a cultivated land quality evaluation model was built using the Analytic Hierarchy Process (AHP), ultimately generating a fine-scale soil quality type map of the Northeast Black Soil Region (raster data with 10 m spatial resolution). The dataset covers the entire Northeast Black Soil Region, with a total data volume of approximately 5.76 GB, and corresponds to the year 2021.</dc:description>
