【摘要】 广东省梅州市丰顺县地处粤东北部地质灾害高发区,是广东地质灾害重点防治区之一。地质灾害的频繁发生,严重影响国家发展和人民生命财产安全。本文以SOPT、ETM+影像和Google Earth Pro软件中的多时相高空间分辨率影像为主要数据,在丰顺县进行遥感地质灾害解译调查,建立了丰顺县地区滑坡、崩塌、不稳定斜坡等地质灾害的解译标志,共解译滑坡52处,不稳定斜坡33处,崩塌10处,地质环境点8处。通过三维多时相高分辨率影像,精细解译地质灾害,分析灾害形成诱因和发育地质环境条件。研究结果表明,遥感技术可以快速、高效地解译出丰顺县地质灾害的种类、规模以及分布特征,完成地质灾害详细调查的前期任务,为地面详细调查提供方向和路线。更多还原

【Abstract】 Fengshun County is located in the high risk area of geological disasters in the northeastern Guangdong Province. It is one of the major geological hazards prevention and control areas in Guangdong Province. Frequent geological hazards have seriously affected the national development and the safety of people’s lives and property. In this paper, the multi-temporal and high spatial resolution images in SOPT, ETM+ images, and Google Earth Pro software are used as the main data to interpret the remote sensing geological hazards in Fengshun County, Meizhou, Guangdong province and establishes the interpretation signs of landslides, collapses, unstable slopes and other geological disasters. 52 landslides, 33 unstable slopes, 10 collapses, and 8 geological environment points were interpreted. Though 3 D multi-temporal high-resolution images, The geological disasters are explained in detail, and the causes of geological disasters and the conditions for the development of geological environment are analyzed. The results show that remote sensing technology can quickly and efficiently interpret the types, scale and distribution characteristics of geological hazards in Fengshun County, complete the preliminary task of detailed investigation of geological hazards, and provide direction and route for detailed investigation on the ground.更多还原
