水利工程区滑坡风险源及其卫星遥感表征规则研究
Characterization rules for landslide hazard sources with satellite remote sensing in hydraulic engineering impact zones
摘要
Abstract
Hydraulic engineering projects are important infrastructures for the benefit of both the country and people.However,but most of them are located in complex geographic environments.Landslides in reservoir areas are one of the hidden dangers affecting their safe operation and are difficult to monitor.In this paper,on the basis of analyzing the geographic conditions,evolutionary characteristics and spatiotemporal distribution of landslide risk sources in hydraulic engineering impact zones,we explore the establishment of the mapping relationship between landslide risk source characteristics and satellite remote sensing parameters,and construct the characterization rules of landslides in reservoir areas with remote sensing indicators such as spectral reflectance,geometric morphology,topography,texture,and morphometric variables.Based on the characterization rules,this paper proposes an automated landslide identification method combining multi-feature joint decision-making and random forest,and introduces a variety of remote sensing features to realize the automated and accurate identification of landslides in the Dawanzi area,and the identification accuracy rate reaches 88.24％.The experimental results show that the satellite remote sensing characterization rules for landslide risk sources established in this paper can provide reliable technical support for landslide remote sensing identification,and have the potential to be widely applied in landslide monitoring in reservoir areas with complex terrain areas or limited ground equipment.关键词
