| 中文摘要:地质灾害调查自20世纪90年代以来经历了多轮发展，目前演变为以孕灾背景调查和隐患点识别的灾害地质调查。“藏东南重要城镇和交通干线地质灾害调查”项目工作区位于西藏东南部，有工作程度落后、地质环境脆弱和工作条件恶劣等特点。项目主要从详实基础地质数据、地质灾害规律和孕灾背景调查评价和地质灾害隐患点识别等3个方面重点进行灾害地质调查工作。为了在藏东南特殊的环境中实现这些调查要求，应用了野外调查数据采集系统、InSAR、三维激光扫描、无人机航测遥感系统和简易观测等技术方法。并且总结了各类调查技术方法的适用性。通过总结经验和找到不足，从而为今后该地区的调查评价提供借鉴和参考。 |

| Abstract:The geological hazard survey has undergone several rounds of development since 1990s, and now it has evolved into a disaster geological survey based on the disaster-formative background investigation and hidden danger identification. Southeast Tibet second-level project is located in southeastern Tibet with the characteristics of inadequate geological work, fragile geological environment and poor working conditions. The project mainly focuses on 3 aspects of the detailed geological data, the law of geological disasters and the evaluation of the disaster-formative background and hidden danger identification. In order to achieve these requirements in the special environment of southeastern Tibet, the field survey data acquisition system, InSAR, 3D laser scanning, UAV aerial survey remote sensing system, simple observation and some other technical methods are applied. The applicability of various survey techniques is also summarized. By summing up experience and finding deficiencies, the reference for future investigation and evaluation in this area can be provided. |
