摘要(Abstract)：

针对潍北平原地区较为严重的地面沉降灾害,该文通过长序列地面沉降监测资料全面掌握了该地区地面沉降现状,为该地区地面沉降的预防治理提供科学依据。该文利用SBAS-InSAR技术对潍北平原地区2017年8月—2019年10月期间的Sentinel-1A数据进行了处理。基于水准测量数据对监测结果进行验证,获取了该区域的地面沉降时空分布特征,对沉降典型特征点的时序形变特征进行了分析,研究了地面沉降与地下水之间的相关性。结果表明:2017—2019年间最大沉降速率超过50(mm·a~(-1))的区域主要包括寿光市羊口镇、营里镇、侯镇,寒亭区大家洼镇、央子镇以及昌邑市龙池镇;地面沉降受地下水超采的影响较为显著,地面沉降漏斗与深层地下水降落漏斗分布特征基本一致。
