| 滑坡地质灾害是各个省份和地区都存在的最为广泛的地质灾害之一，每年都造成巨大的人身伤亡和财产损失。为最大限度地减少地质灾害造成的人员伤亡和财产损失，各省都建立了监测预警系统，用以应对滑坡地质灾害。在众多监测系统中， GNSS技术独树一帜，不仅预警结果精确，还实现了全时段无人自动监测，能最大限度地减少人财损失。本文以曲靖市麒麟区一滑坡为例研究 GNSS技术在滑坡监测预警中的具体应用，通过对该滑坡持续进行 3年的 GNSS监测，对系统发布的预警信息、数据予以分析研判，结果表明该系统监测预警准确率 95%以上，有效保护了该地质灾害点受威胁财产和受威胁人员，取得了良好的社会效益和经济效益，从而深入探讨滑坡地质灾害中 GNSS技术的监测预警作用，进一步加强防灾备灾体系和能力建设，全面提高滑坡地质灾害风险防御和应急处置能力。 |

| Landslide geological disaster is one of the most extensive geological disasters existing in variousprovinces and regions，which causes huge personal casualties and property losses every year. In order to minimizethe casualties and property losses caused by geological disasters，all provinces have established monitoring andearly warning systems to deal with landslide geological disasters. In many monitoring systems，GNSS technology is unique，not only the early warning results are accurate，but also the realization of the whole period of automatic monitoring，can minimize human and financial losses. This paper takes a landslide in Qilin District，Qujing Cityas an example to study the specific application of GNSS technology in landslide monitoring and warning. Through continuous GNSS monitoring of the landslide for three years，the early warning information and data issued by thesystem are analyzed and evaluated. The results show that the monitoring and warning accuracy rate of the system isabove 95%，which effectively protects the threatened property and threatened personnel in the geological disastersite. Good social and economic benefits have been obtained，so as to further explore the monitoring and early warn.ing function of GNSS technology in landslide geological disasters，further strengthen the disaster prevention and preparedness system and capacity construction，and comprehensively improve the risk prevention and emergencydisposal capacity of landslide geological disasters. |
