摘　　要：高程基准是测绘基准的重要组成部分,可为国家重大工程提供数据支撑。针对高程基准因受地表形变等因素影响而难以精准监测的问题,本文基于时序InSAR地表形变监测和水准数据时间序列分析地表形变结果,对形变区开展高程基准周期性复测,实现以高程基准成果更新、点位可用性分析、点位沉降情况分析为主要内容的动态监测,并以山东省为例进行实验。结果表明,该方法能有效降低监测成本和监测难度,成果可靠性强,可有效提升测绘基准保障能力和服务质量,为区域高程基准动态监测提供一种新思路。The elevation datum is an important component of the surveying and mapping datum,providing data support for major national projects.Addressing the issue of accurately monitoring elevation datum affected by factors such as surface deformation,we present a study to analyze surface deformation based on time-series InSAR data and leveling time-series data.The study conducts periodic remeasurement of elevation datum in deformation area,achieving dynamic monitoring primarily through updating elevation datum,point usability analysis,and point subsidence analysis.Taking Shandong province as an example,we carry out an experiment.The results show that the method proposed in this paper can effectively reduce monitoring costs and difficulties,yield reliable results,significantly enhance the supportability and service quality of surveying and mapping datum,and provide a new dynamic monitoring approach for regional elevation datum.
