摘要

摘要: 极端降雨事件诱发的群发性滑坡泥石流灾害已成为我国乃至全球面临的主要自然灾害之一。本文选择2016年“莫兰蒂”台风极端降雨触发的泰顺群发性滑坡灾害作为典型研究案例，基于高分辨率光学遥感影像、LiDAR测量数据等开展灾害精细解译和遥感识别，结合野外核查验证，构建了包含3628处浅层滑坡和1584处坡面泥石流的灾害编目数据库。研究结果表明，研究区降雨型地质灾害整体表现为点多、规模小、密度高、群发突发性强的发育特征，属于典型的滑坡–泥石流复合链生灾害。空间分布格局受控于极端降雨阈值、岩性条件以及地形地貌等多因素耦合作用，南向坡、凹形坡、坡度25°～45°的斜坡及花岗岩风化区岩土体稳定性差，为滑坡泥石流高敏感区段；滑坡泥石流中高密集发育区与降雨集中区基本吻合，但局部降雨极值中心灾害发育密度偏低，证实岩性、坡度、高程等内在因素起到关键筛选和控制作用。坡面泥石流沟启动区浅层滑坡地貌特征精细化识别表明，细沟源头、坡度陡缓转换带以及历史变形痕迹等特殊区域，是控制泥石流启动的关键孕生带，据此建立了极端降雨条件下坡面泥石流的灾害链演化模式。本文相关成果可为未来极端降雨触发的群发滑坡泥石流精准识别与防范提供科学参考。

Abstract: Extreme rainfall-induced clustered landslide and debris flow hazards have become one of the primary natural disasters in China and globally. In this study, the clustered landslide disaster in Taishun triggered by extreme rainfall of Typhoon Meranti in 2016 was selected as a typical case. Fine interpretation and remote sensing identification of geo-hazards were carried out using high-resolution optical remote sensing images and LiDAR data. Combined with field investigation and verification, a geo-hazard inventory database was established, including 3628 shallow landslides and 1584 slope debris flows. The results reveal that rainfall-induced geo-hazards in the study area are characterized by large quantity, small individual scale, high spatial density and strong sudden clustered occurrence, which belong to typical compound chain-type landslide-debris flow disasters. The spatial distribution is dominated by the coupling of extreme rainfall threshold, lithology, topography and geomorphology. South-facing slopes, concave slopes, terrain gradients of 25°-45°, and weathered granite areas present poor stability of rock and soil masses, serving as high-susceptibility zones for landslides and debris flows. Moderate-to-high concentration areas of landslides and debris flows are generally consistent with rainfall concentration zones where the maximum 1-hour rainfall exceeds 70 mm and the maximum 3-hour rainfall exceeds 120 mm. However, the disaster density is relatively low at local rainfall extreme centers, confirming that intrinsic factors such as lithology, slope gradient and elevation exert critical controlling and filtering effects. Refined geomorphological identification of shallow landslides in the initiation zones of slope debris flow gullies indicates that gully head areas, gradient transition zones and historical disaster scar zones are critical gestation zones dominating debris flow initiation. Accordingly, an evolutionary model of the slope debris flow disaster chain under extreme rainfall was constructed. The research findings can provide a scientific reference for the accurate identification and prevention of clustered landslide and debris flow hazards triggered by extreme rainfall in the future.
