摘　　要：随着地质灾害的破坏性增大,高效、精准的地质灾害防治成为鹤壁市政府部门、技术单位的重点工作。为了调查鹤壁市在洪灾过后的地质灾害隐患,本文利用光学卫星、雷达卫星、无人机等多源遥感技术,开展鹤壁市地质灾害遥感调查,探索多源遥感技术对鹤壁市地质灾害的识别能力与有效性。结果表明,光学卫星影像对研究区中滑坡、泥石流地质灾害能够有效识别,但对崩塌等小型地质灾害识别效果较差,需要借助无人机遥感手段进一步调查;地面塌陷地质灾害在光学遥感数据中难以识别,雷达遥感数据能够有效识别其范围及形变特征。因此,在鹤壁市地质灾害的识别和应急调查中,利用多源遥感技术相互协作、优势互补的综合调查识别的方法,能够为研究区地质灾害防治工作提供基础数据和防治依据。With the increasing destructiveness of geologic hazards,efficient and accurate prevention and control of geologic hazards has become a key task for government and technical departments in Hebi City.In order to investigate the hidden geologic hazards after the flood in Hebi City,we using multi-source remote sensing(MSRS)technologies such as optical satellites,radar satellites,and unmanned aerial vehicles(UAVs)to identify geologic hazards,and test its identifying ability and effectiveness.The results show that optical satellite images can effectively identify landslides and mudslides,but the small-scale geologic hazards such as ground subsidence is less effective,and needs to be further investigated by UAVs,the radar remote sensing data can effectively identify the range and deformation characteristics of ground subsidence.Therefore,the application of comprehensive investigation and identification methods such as MSRS is very effective in the identification and emergency investigation of geologic hazards.
