Dataset for: A threshold-driven framework for mechanism-oriented zoning of cultivated land fragmentation in the Yellow River Basin

This dataset package contains derived county-level indicators, model-ready tables, SHAP and threshold exports, zoning outputs, and lightweight figure-reproduction support files for the manuscript "A threshold-driven framework for mechanism-oriented zoning of cultivated land fragmentation in the Yellow River Basin". The package is prepared to support reproducibility of the submitted/revised manuscript and does not redistribute large third-party raw datasets with independent repositories and licenses. Included contents cover: (1) county-level derived indicators and CLFI-related variables, (2) model-ready matrix with train/test split labels for CatBoost analysis, (3) county-level pattern classification outputs, (4) plot-ready SHAP/regression/LOWESS/histogram/threshold exports, (5) county-level merged means for mechanism-oriented zoning comparisons, and (6) lightweight plotting scripts for key derived figures. Upstream base datasets (e.g., CLCD, ASTER GDEM V3, climate products, LandScan, OpenStreetMap, and RESDC) should be obtained from their original sources and licenses.
