摘要
昆明市官渡区为云南省地质灾害较严重的地区之一,在对研究区地质概况充分了解的基础上,收集了ETM、高分一号、Quickbird等遥感影像,从而对研究区内进行灾害遥感解译。综合分析官渡区内地质灾害的类型、规模、以及分布规律,建立该区的地质灾害解译标志;并对地质灾害易发性进行分区评价,分析地质环境发展趋势,为野外勘查提供合理路线。本次共解译了地质灾害点共43处,以滑坡、崩塌灾害为主。
Guandu district of Kunming is one of the region where has severe geological hazards in Yunnan Province. Based on the study of the geological conditions in Guandu district, collecting RS data such as GF-1,ETM and Quickbird, interpret the geological hazards with RS in the study area. Synthetically analyse the type, scale and distribution of geological hazards in Guandu district, and establish the interpretation key of geological hazards in this area. Evaluate the easily happened area of geological hazards, analysis the development trend of geological environment and provide reasonable route for field investigation. There are 43 geological hazards points in this interpretation, which chiefly landslide and collapse hazard.
