AI Technical Summary

Technical Problem

Existing regional extreme climate risk assessment methods are difficult to achieve high-precision spatial calibration under multi-hazard coupled scenarios, resulting in discontinuous or distorted assessment results. This is especially true in areas with sparsely distributed monitoring points or complex underlying surfaces, making it difficult to accurately reflect the true spatial pattern of hazard chain risks.

Method used

By constructing a spatial tetrahedron and combining grid point location determination with force component calculation to generate a continuous risk deviation correction field, the risk value at the standard spatial scale is corrected based on the measured risk value and deviation of the field calibration points. The interaction and chain effects of extreme climate events are analyzed, and the risk evolution trend is dynamically predicted by combining future climate change scenario simulation data.

Benefits of technology

It achieves high-precision coupling calibration between large-scale standardized risk values ​​and local measured risk conditions, effectively avoiding the discontinuity and distortion of risk assessment results in complex underlying surface areas, and providing assessment results that are more in line with the actual risk pattern of the region, thus providing a basis for regional disaster prevention and mitigation decision-making.

Abstract

The application provides a multi-disaster coupling regional extreme climate comprehensive risk assessment method and system, relates to the technical field of data processing, and comprises the following steps: 1, fusing and converting multi-source data in a target evaluation region to form a risk element data set, and calculating the risk value of each extreme climate event under a standard spatial scale; 2, extracting historical monitoring data of four real calibration points in the target evaluation region, and calculating the measured risk value of each real calibration point and the real risk deviation of each real calibration point. Through multi-source data fusion, real calibration, spatial tetrahedron determination and deviation correction, the multi-disaster coupling effect and the chain effect are analyzed, the risk evolution is dynamically estimated in combination with a future scenario, and decision support is provided for the extreme climate comprehensive risk prevention and control and adaptation of the target evaluation region.
