2024年6月16日,闽粤赣边区发生极端强降雨事件诱发数以万计的滑坡灾害,造成大量人员伤亡和财产损失.快速查明滑坡特征与驱动因素可为灾害预报预警和风险防控提供数据支撑.利用灾后光学影像进行智能识别,结合现场抽检复核,分析滑坡的空间分布和发育特征,并结合气候生态因素、地质条件和地形地貌探讨驱动因素.结果显示,共解译滑坡35 407处,总面积约41.27 km2;以小规模为主,集中分布在雨量超240 mm的山区;自然滑坡形状较规则、流动性强,工程滑坡形态复杂、流动性较弱.滑坡分布受气候生态因素、地质条件和地形地貌特征显著影响;自然滑坡受地形主导,而工程滑坡则随机性更强.本研究深化了对群发滑坡特征和驱动机制的理解,为防灾减灾救灾提供科学依据.
On June 16, 2024, an extreme rainfall event occurred in the Fujian-Guangdong-Jiangxi junction area, triggering tens of thousands of landslides and causing significant casualties and property losses. This study aims to rapidly identify the characteristics and driving factors of landslides to provide data support for disaster forecasting, early warning, and risk management. Post-disaster optical imagery was used for intelligent landslide identification, supplemented by on-site validation, to analyze the spatial distribution and developmental characteristics of the landslides. The study further investigated the driving factors by integrating the meteorological, ecological factors, geological conditions topographic features. The results reveal a total of 35 407 landslides, covering an area of approximately 41.27 km2, predominantly small-scale and concentrated in mountainous areas where rainfall exceeded 250 mm. Natural landslides exhibited relatively regular shapes and higher mobility, while landslides induced by engineering activities showed more complex shapes and lower mobility. The distribution of landslides was significantly influenced by the meteorological, ecological factors, geological conditions and topographic characteristics. Natural landslides were primarily controlled by topography, whereas engineering-induced landslides displayed greater randomness. This study deepens the understanding of the characteristics and driving mechanisms of clustered landslides, providing valuable scientific guidance for disaster prevention, mitigation, and relief efforts.
