随着习近平生态文明思想的全面深入推进和山水林田湖草沙一体化统筹治理的提出,以生态文明为指导思想的煤炭采空区矿山生态修复与保护工作越来越重要,对采煤区的地表形变进行时序监测在地质灾害防灾减灾和矿山生态修复工作中具有重要意义。以白山市辖区(浑江区、江源区)浑江煤田作为研究对象,获取2017年1月18日—2021年12月11日共131景C波段Sentinel-1B降轨数据,采用小基线集(SBAS-InSAR)技术方法对研究区地面沉降进行时序监测,分析地面沉降速率和沉降量的发展规律,并用光学遥感影像和实地调查验证监测结果的可靠性。结果表明,监测期间研究区内形成5处明显的地面沉降区,沉降区总面积8.96 km
