Spatial heterogeneity of wind-eroded soil particles around <i>Nitraria tangutorum</i> nebkhas in the Ulan Buh Desert
Bibliographic record
Abstract
Nitraria tangutorum is a widely distributed shrub in the Jilantai Salt Lake at the southwest edge of Ulan Buh Desert. Due to their role in increasing soil fertility, nebkhas (coppice dunes) are regarded as important components of arid land ecosystems. Yet, despite their frequent occurrence, little information exists regarding their dust fall effect and influence range. We investigated the grain size distribution around N. tangutorum at a small scale (within 10 m) according to four wind directions and analyzed the spatial heterogeneity of particles. The amount of non-erodible particles (>0.85 mm) increased with distance from the shrub. The amount of erodible (<0.45 mm) and semi-erodible particles (0.45–0.85 mm) showed an opposite trend, indicating that the shrubs have a protective effect. The dominant particles around the shrubs were non-erodible due to long term accelerated wind erosion and subsequent removal of fine particles.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
