Abstract

fetched live from OpenAlex

Based on the MSS images in 1976 and the TMimages in 1989,2000 and 2010,the changesof land use/coverage and landscape pattern and their driving force in Taolai River Basin were analyzed from 1976 to 2010 by using principal component analysis method in combination with landscape indexes and the methods of variation amplitude,dynamic degree and transfermatrix.The results indicated thatduring the recent34 years after1976,the proportionsof cultivated land and construction land expanded sharply from4%and 0.04%to 7.4%and 0.26%,respectively;while the area of glaciers and permanent snow and grassland decreased by 897.98×104hm2and 383.7×104hm2,respectively.Among the various typesof land use,construction landwas the highestin dynamic degree(16.13%),followed by cultivated land.The conversion of glaciers and permanent snow into bare rocks,the conversion of gobi into cultivated land and the conversion between forestland and grasslandwere the main trendsof land use variation.The patch density of total landscape increased at first and decreased later,while the largest path index decreased at first and expended later.Therefore,the shape of landscape became more and more irregular,and the degree of landscape diversity decreased at first increased later.The population growth and economic development were the most direct driving forces of land use/coverage changes in Taolai River Basin,and climatic factors also affected land use/coverage changes to some extend.

Full frame distilled prediction

Teacher imitation

Not 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.
