摘　　要：在地质灾害调查中及时识别和排查潜在的隐患灾害点对地质灾害的预防和监测工作至关重要。然而传统的地质灾害排查方法时间和人力成本较高,难以实现对广泛区域的全面排查。本文通过对青海省大通回族土族自治县城关镇区域内的地质灾害情况进行详细的调查,获取了区内的地质灾害分布特征。并进一步采用了哨兵1号(Sentinel-1)雷达数据,利用差分干涉测量短基线集时序分析(SBAS-InSAR)技术进行数据处理,成功揭示了该区域的地表形变情况。通过综合分析,能够准确地识别出重点监测区域的变化信息,从而提高了地质灾害及时预防和应对的效率。It is crucial to timely identify and investigate potential hidden disaster spots in geological hazard investigations for the prevention and monitoring of geological hazards.However,traditional geological hazard investigation methods are time-consuming and labor-intensive,making it difficult to conduct comprehensive investigations in a wide area.In this paper,a detailed investigation of geological hazards in Chengguan Town,Datong County,Qinghai Province was conducted,and the distribution characteristics of geological hazards in the area were obtained.Furthermore,Sentinel-1 radar data was used and processed using a small baseline subset-interferometric synthetic aperture radar(SBAS-InSAR)technology,successfully revealing the surface deformation in the area.Through comprehensive analysis,the changes in key monitoring areas could be accurately identified,thereby improving the efficiency of timely prevention and response to geological hazards.
