Abstract

fetched live from OpenAlex

Located in the central part of the Hexi Corridor, the Heihe River rises in the Qilian Mountain and flows through Qinghai Province, Gansu Province and Inner Mongolia Autonomous Region, it is one of the large continental rivers in northwest China, and its length and catchment area are 821 km and 1.3×105 km2 respectively. Because of the impacts of natural factors and human activities, the vegetation is degenerated, the Ejina Oasis is shrinking, and the ecological environment is degenerated due to the drawdown of groundwater level caused by the reduction of the stream flow to the lower reaches. All these have been paid a great attention to. Considering from the shortage of the local surface water resources, it is suggested to reduce the seepage along the river channel in the lower reaches of Heihe River by some engineering measures. However, the vulnerable ecology relies on the limited stream water and groundwater for its existence. In this paper, the lysimetric experiment on the riverbed in the lower reaches of Heihe River is carried out. After measuring the seepage along the riverbed in the lower reaches of Heihe River by using the Model 2800 Guelph lysimeters, it is found that the penetration power of the riverbed is very strong, which is necessary for recharging groundwater from stream flow and also the necessary conditions for maintaining the vegetation in the lower reaches and for the existence of Ejina Oasis. Therefore, it is considered that the groundwater recharge will be reduced, the vegetation in the lower reaches will be further degenerated, and the safety of Ejina Oasis will be threatened if the engineering measures are applied for reducing the seepage along the river channel in the lower reaches of Heihe River.

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.
