摘　　要：【目的】获取桂林市兴安县羊角山区域的地面形变监测结果,探究人类活动对地面形变的影响。【方法】采用2017年3月17日—2021年12月9日覆盖羊角山地区的90景升轨Sentinel-1A卫星影像作为数据源,基于SBAS-InSAR方法对该区域进行地面形变监测分析,SBASInSAR方法能够有效地减弱时空失相干扰和大气效应引起的误差,提高地面形变监测结果的准确性。【结果】在长时间序列的小尺度地表开发形变监测上使用SBAS-InSAR方法仍能得到较高精度的结果,研究区域地表平均形变速率处于-18 mm/a~10 mm/a,在研究区的西南方向累积形变量最大,达到了-60 mm。【结论】该区域由于开发时间长度和开发强度的不同表现出不同的形变结果,且随着对该区域的持续开发,整体形变量有继续增加的趋势。[Purposes] To obtain the monitoring results of ground deformation in Yangjiao Mountain,Xing′an County,Guilin City,and show the impact of human activities on ground deformation.[Methods]In this paper,90 satellite images of Satinel-1A,which covered the Yangjiao Mountain area from March17,2017 to December 9,2021,are used as the data source to monitor and analyze the ground deformation in the area based on the SBAS-InSAR method,which can effectively reduce the errors caused by spatiotemporal incoherence and atmospheric effects,and improve the accuracy of the ground deformation monitoring results.[Findings] The SBAS-InSAR method can still obtain high precision results on the small-scale surface development deformation monitoring of long time series.The average surface deformation rate in the study area is between-18 mm/a and 10 mm/a,and the maximum cumulative deformation in the southwest of the study area is-60 mm.[Conclusions] The region shows different deformation results due to different development time length and development intensity,and with the continuous development of the region,the overall deformation variable continues to increase.
