The change process and influencing factors of channel connectivity in Jingjiang River from 1955-2015
Bibliographic record
Abstract
Human activities have greatly reduced the sediment load in the Yangtze River Basin and have changed the channel connectivity of the Jingjiang River. In this paper, the analytic hierarchy process (AHP) is used to establish the assessment model of channel connectivity based on the river function. Then, combined with the flow, sediment and boundary data of the main hydrological stations, we analyze the variation in processes of the channel connectivity of the Jingjiang River from 1955 to 2015. The results show that the change in process of channel connectivity of the Jingjiang River is basically the same in different reaches. The value of the comprehensive function of connectivity increases gradually with time and is greater than 1.0 after 1990, indicating that the channel connectivity has improved. Spatially, the Shashi-Jianli reach has the best connectivity, while the Zhicheng-Shashi reach has the worst connectivity. In addition, reservoir construction and river straightening are the main factors affecting the channel connectivity of the Jingjiang River. The influence of water and soil conservation on channel connectivity is mainly realized by basin erosion, which is the secondary factor. Some research methods and results can be used as reference for studying channel connectivity in other basins.

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.
