| 摘 要： | 采用北斗卫星定位技术对滑坡地表位移进行实时监测是构建"人防+技防"地质灾害监测预警体系的有效技术手段。本文梳理了目前北斗位移监测系统的应用现状，分析了"一点一基站"模式在规模化应用中存在的问题，提出了基于虚拟参考站（Virtual Reference Station，VRS）技术的滑坡高精度位移监测系统设计方案，并结合黄土地区滑坡监测预警工作实际需求在陕西省榆林市佳县开展了示范应用，总结出"虚拟基站+自适应解算"的技术路线，为北斗卫星定位技术在地质灾害监测预警中规模化应用提供了实践经验。

| Abstract: | Using Beidou satellite positioning technology to monitor the surface displacement of landslide in real time is an effective technical means to construct the geological disaster monitoring and warning system based on human’s prevention and technical prevention. The current application status of Beidou displacement monitoring system was summarized, the problems existing in the large-scale application of "one-point-one-reference Station" mode analyzed and the design scheme of landslide high-precision displacement monitoring system based on VRS (Virtual Reference Station) technology was proposed. Besides, Based on the actual needs of landslide monitoring and early warning in loess region, a demonstration application was carried out in Jia County, Yulin City, Shaanxi Province, and the technical route of "virtual reference station + adaptive calculation" was summarized, which provided practical experience for the large-scale application of Beidou satellite positioning technology in geo-hazard monitoring and early warning. |
