摘　　要：【目的】地质灾害监测对防灾减灾服务、路网规划、城镇建设具有重要意义,需对其进行研究。【方法】以地质灾害频发的G316国道南平至闽清段交通干线作为示范区,采用机载激光雷达、无人机低空摄影测量等先进技术手段,采集并处理示范区地质灾害体高分辨率正射影像,并建立数字高程模型,联合多元遥感信息,解译地质灾害体空间形态特征。【结果】建立了数字三维可视的滑坡、崩塌等地质灾害基础信息。【结论】可为今后周期性巡查、评价、监测地质灾害及快速应急、安全排险突发性地质灾害等提供服务。[Purposes]Geological disaster monitoring research is of great significance to disaster prevention and mitigation services,road network planning,urban construction and other decisions,so it needs to be studied.[Methods]Taking the traffic trunk line from Nanping to Minqing section of G316 national highway with frequent geological disasters as the demonstration area,advanced technical means such as airborne radar and low-altitude photogrammetry were used to collect and process high-resolution orthoimages and digital elevation models of geological disaster bodies in the demonstration area,and combined with multivariate remote sensing information,the spatial morphological characteristics of geological disaster bodies were interpreted.[Findings]The digital three-dimensional visual basic information of geological disasters such as landslide and collapse was established.[Conclusions]The study can provide services for future periodic inspection,evaluation,monitoring,rapid emergency response and safety risk elimination of sudden geological disasters.
