摘　　要：该文以辽源西安煤田地表沉降现象作为研究对象,采用SBAS-InSAR技术进行监测,从地表沉降空间分布格局、时空演化特征、典型沉降区时间序列分析和地表沉降程度分级四个方面出发,综合分析该矿区2017~2021年间的地表沉降时空演化趋势和变化特征。结果表明:辽源西安煤田存在三处典型的地表沉降区,均呈加剧沉降的趋势,位于灯塔镇境内的沉降区沉降最为严重;通过对沉降程度分级更直观地了解了各沉降区的沉降严重程度。通过精度评估和野外实地调查,验证了SBAS-InSAR监测结果的可靠性,可为辽源西安煤田的地质灾害防治和环境保护提供重要的科学依据。This paper investigates land subsidence of Xi′an coalfield in Liaoyuan using SBAS-InSAR technology for spatiotemporal monitoring.It examines spatiotemporal evolution trends and change characteristics of land subsidence of Xi′an coalfield in Liaoyuan from 2017 to 2021 by focusing on four key aspects:spatial distribution of land subsidence,spatiotemporal evolution characteristics,time-series analysis of typical subsidence areas,and land subsidence classification.The results indicate that there are three typical land subsidence areas in the coalfield,all demonstrating an intensifying subsidence trend.The subsidence in Dengtai Town is the most severe.The classification of subsidence severity provides a clearer understanding of the severity levels in affected areas.The reliability of the SBAS-InSAR monitoring results is verified through accuracy assessment and field investigation.These findings offer valuable scientific insights for geological hazard prevention and environmental protection of Xi′an coalfield in Liaoyuan.
