AI Technical Summary

Technical Problem

Existing methods for assessing the ecological impact of highway construction and operation are mainly static evaluations, which make it difficult to achieve dynamic tracking and real-time feedback of ecological impacts throughout the entire life cycle. The assessment indicators are isolated and superimposed, which cannot adapt to the dynamic changes in the ecological sensitivity and environmental carrying capacity of different regions, resulting in assessment results that are lagging, inaccurate, and lack guidance.

Method used

The engineering disturbance index and ecosystem resilience index are calculated using multi-source time-series monitoring data. The engineering disturbance index is dynamically corrected by the ecosystem resilience index to construct a dynamic critical disturbance threshold. Furthermore, correction factors are generated through transfer learning to achieve dynamic hierarchical assessment of ecological impact.

Benefits of technology

It achieves accurate, real-time, dynamic hierarchical assessment of the ecological impact throughout the entire life cycle of highways, integrates the dynamic cumulative effect of engineering disturbances with the real-time response of the ecosystem, and has significant dynamism and adaptability, supporting the optimization of engineering practicality.
