AI Technical Summary

Technical Problem

Existing technologies lack specificity and systematicity in soil and water conservation in engineering-disturbed areas. In particular, the effectiveness of these technologies is unstable under special site conditions such as high-altitude cold regions and hot and dry valleys. They also lack precise monitoring and comprehensive assessment. The uniformity of parameters in traditional models leads to inaccurate calculations of erosion, and risk assessments are one-sided, making it difficult to achieve precise prevention and control and long-term restoration.

Method used

A closed-loop technical system is adopted, which includes precise monitoring by drones, correction of regional policy models, three-dimensional risk assessment and gradual ecological restoration. Through the acquisition of sub-meter high-resolution images and hyperspectral data, the soil erodibility factor is refined by the regional policy model. Multidimensional disturbance correction coefficients and multi-force coupling correction factors are introduced to construct a three-dimensional risk index system, implement governance measures in stages and establish a dynamic optimization mechanism.

Benefits of technology

It enables precise prevention and systematic management of soil erosion in engineering disturbance areas, improves the accuracy of soil erosion modulus calculation, accurately identifies high-risk areas, reduces waste of management resources, adapts to different disturbance types and site conditions, and has wide applicability.
