摘要
LT-1卫星作为我国第一组民用干涉卫星,为地质灾害隐患综合遥感常态化监测识别提供了可靠的数据支撑。为验证LT-1卫星在江西植被高覆盖区的丘陵山区形变监测效果,采用Stacking技术和光学遥感解译相结合的综合遥感识别方法,对江西省萍乡地区开展地质灾害隐患识别,共识别出疑似隐患点195处,经野外核查确认隐患点46处。研究结果表明:条带模式二下的LT-1卫星数据对地面塌陷、崩塌、地面沉降隐患识别效果较好;可识别植被茂密地区的小型滑坡隐患,对中型及以上滑坡隐患识别具有较好的适用性。
As the first group of civilian interference satellites in China,LT-1 satellite has provided reliable data support for normalized monitoring and identification of geological hazards through comprehensive remote sensing.In order to verify the deformation monitoring effect of LT-1 satellite in the hilly and mountainous areas with dense vegetation coverage in Jiangxi province,a comprehensive remote sensing identification method combining Stacking technology and optical remote sensing interpretation has been used to identify geological hazards in Pingxiang area in Jiangxi Province.A total of 195 suspected hidden danger points have been identified,and 46 hidden danger points have been confirmed through field verification.It is indicated that LT-1 satellite data in Band Mode 2 performs well in identifying hidden dangers,such as ground subsidence,collapse and subsidence.It can identify small landslide hazards in densely vegetated areas and has good applicability for identifying medium and above landslide hazards.
