The Analysis of Evolution Characteristics and Formation Mechanism of Population Distribution in Northeast China
Bibliographic record
Abstract
Based on population concentration index,population gravity center model,spatial autocorrelation analysis,this study analyzes the temporal-spatial evolution characteristics of population distribution of 36 cities in Northeast China and discusses the formation mechanism by choosing the years of 1990、2000、2010 and 2013.The analysis results show that;the characteristics of the population distribution in the south of the Northeast China is denser than the north and presents a condition of progressive decrease as a ladder from the south to the north;the density of population grows slowly,and some cities appear negative growth;the population distribution has continually central tendency,the population gravity center moves from northeast to southwest;the population density has strong spatial correlation in each city,the H- H agglomeration areas are mainly focused on the Iiaoning province,the L-L agglomeration areas are mainly concentrated in the Heilongjiang province,and both have a good stability.Sum up,the spatial evolution of population distribution of Northeast China is influenced by the natural environment,the level of economic development,transportation accessibility,historical foundations and policies.

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.
