| 摘 要： | 本文以地热资源丰富的雄安新区为研究对象，利用SBAS技术对2015年7月至2019年2月的42幅Sentinel-1区域卫星影像和2016年8月至2018年12月的10幅ALOS-2区域卫星影像进行处理，以此获取雄安新区的时间序列地表形变。研究结果表明，雄安新区整体地表沉降严重，且沉降区主要集中在雄县和容城县，其中雄县沉降最为严重，沉降中心累计沉降量超过330 mm，容城县沉降中心累计下沉量超过120 mm。结合地热井位置和地热开采历史，由时间序列分析表明，大量开采地热资源会引起地表沉降现象。

| Abstract: | This article takes the Xiongan New Area, which is rich in geothermal resources, as the research object. Using SBAS technology to process 42 Sentinel-1 regional satellite images from July 2015 to February 2019 and 10 ALOS-2 regional satellite images from August 2016 to December 2018 to obtain the time-series surface deformation of Xiongan New Area. The results of the study show the Subsidence of Xiongan New Area is serious, and the subsidence areas are mainly concentrated in Xiong County and Rongcheng County. Among them, Xiong County has the most serious subsidence. The accumulated subsidence of the center exceeds 330 mm. The cumulative subsidence of the subsidence center in Rongcheng County exceeds 120 mm. Combining the location of geothermal wells and the history of geothermal exploitation, time-series analysis shows that large-scale exploitation of geothermal resources will cause surface subsidence.and the accumulated subsidence of the subsidence. |
