摘　　要：建昌县频发的群发性泥(水)石流是当地最为严重的地质灾害之一,对居民安全和基础设施构成了严重威胁。为揭示泥石流的孕灾机制,通过结合遥感影像、数字高程模型(DEM)及野外调查数据,系统分析了建昌县泥石流灾害的分布规律及其与孕灾地质条件的关联性,包括地形参数、工程地质岩组、断裂构造及植被指数(NDVI)等因素,探讨了泥石流的发育特征及其时空分布规律,系统性的野外调查验证了上述分析成果,旨在减轻未来可能发生的泥石流对承灾体的影响,为建昌县地质灾害精细化防治及风险管控提供科学依据。The frequent occurrence of debris flows in Jianchang County are one of the most serious geological disasters in the area,posing a serious threat to residents’safety and infrastructure.To reveal the disaster-generating mechanism of debris flows,a systematic analysis was conducted on the distribution pattern of debris flow disasters in Jianchang County and its correlation with disaster-generating geological conditions,including topographic parameters,engineering geological rock formations,fault structures,and vegetation index(NDVI),by combining remote sensing images,Digital Elevation Models(DEM),and field survey data.The development characteristics and spatial-temporal distribution patterns of debris flows were explored,and the above analysis results were verified by systematic field surveys,aim to mitigate the impact of possible future debris flows on the disaster-bearing body,and provide a scientific basis for the refined prevention and risk management of geological disasters in Jianchang County.
