The spatio-temporal evolution characteristics of landscape fragmentation for Xining City in recent 15 years
Bibliographic record
Abstract
Spatiotemporal evolution processes of land use dynamic change and landscape fragmentation change in Xining city were quantitatively analyzed through dynamic attitude,landscape index in this paper. The analysis used three phases of Landsat remote sensing image of 1995,2003,2010 for information source,and Erdas9. 2, Fragstats3. 3 and SPSS16. 0 software were used. The results showed that:( 1) In study area,construction land and woodland continued to grow,net growthes were 4068. 09hm2and 1473. 39hm2respectively for 15 years,cultivated land and bare land continued to decrease,net dereases were 4058. 28hm2and 1481. 85hm2respectively.( 2) The land use dynamics were significant differences among the landscape type stages. In 1995-2003,the construction land,woodland,arable land,bare land and water dynamic degcees were 4. 93%,2. 44%,4. 00%,1. 54% and0. 02% respectively; In 20032010,they were 2. 85%,0. 56 %,2. 38%,3. 17% and0. 02%.( 3) land landscape fragmentation degree intensified for the past 15 years in study area,but the phase difference between the 19952003 and 20032010 was fairely great,It showed that the dominant patchbased construction land and other landscape types did not balancet.

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.
