摘要(Abstract)：

为了获取杭州湾上虞地区地面沉降信息,该文利用SBAS-InSAR技术处理了2017年3月—2018年11月共48景Sentinel-1A数据,将监测结果与同期水准测量数据进行比较,并分析不均匀地面沉降的主要原因。结果表明:上虞地区地面沉降程度总体由北向南逐渐减弱,其中,北部新近围垦区内的上虞杭州湾工业园区地面沉降显著,最大沉降速率为-27.9 mm/a,属于地面沉降地质灾害高易发区,海涂围垦、回填土固结沉降是其主要原因;上虞中北部地区(如崧厦镇、谢塘镇),受围垦、工业活动的影响,沉降速率在-7～-23 mm/a之间;百官街道、曹娥街道和东关街道等中心城区存在不均匀地面沉降,主要与城市开发工程建设有关;在南部乡镇地区,因靠近丘陵山脉、地层岩性影响,地面沉降不明显;此外,该区75个不稳定地质灾害隐患点总体较为稳定。
