AI Technical Summary
Existing technologies lack multi-scale nonlinear pressure transmission mechanisms and dynamic coupling capabilities with ecological responses in assessing the cumulative impact of offshore wind power projects on biodiversity. This results in insufficient assessment accuracy and an inability to accurately describe complex ecological processes such as turbulent eddy disturbances and habitat connectivity disruptions.
By collecting data on the current status of marine life and pressure sources from wind power projects, multi-scale spatiotemporal decomposition is performed to establish a hierarchical cumulative pressure identification system. The core region of turbulent vortex is identified by velocity gradient tensor eigenvalue decomposition. An ecological response spiral extrapolation model with a spiral progressive network structure is constructed. Combined with a nonlinear network model of synergistic amplification and antagonistic cancellation transfer functions, the cumulative impact index is calculated.
It enables accurate assessment of the multi-scale nonlinear pressure transmission mechanism and dynamic coupling of ecological response in offshore wind power projects, improves the accuracy of assessment of turbulent mixing disturbances and habitat connectivity changes, and provides suggestions for ecological restoration.
