摘要
利用遥感地质解译和地理信息技术手段,结合地质、环境、遥感等信息,开展了罗山县地质灾害风险调查。通过野外排查,对罗山县地质灾害和孕灾地质条件建立解译标志,根据解译标志及专家经验,对获取的遥感影像进行人机交互解译,并对解译结果进行定量分析,初步查明了工区地形地貌、地质构造、植被覆盖度、工程地质等因子,为后续易发性评价和风险评价提供数据支持。
The geological disaster risk survey of Luoshan County was carried out by means of remote sensing geological interpretation and geographic information technology,combined with geological,environmental and remote sensing information.Interpretive markers were established for geological disasters and disaster-prone geological conditions in Luoshan County through field investigation.According to the interpretive markers and expert experience,human-computer interactive interpretation was carried out on the obtained remote sensing images,and quantitative analysis was carried out on the interpretation results.The factors of topography,geomorphology,geological structure,vegetation coverage and engineering geology in the working area were initially identified.To provide data support for subsequent susceptibility assessment and risk assessment.
