摘　　要：结合矿山泥石流自身特点,提出基于小流域划分的矿山泥石流遥感解译技术方案:首先,基于数字高程模型划分小流域范围;其次,根据地形地貌因子提取地形起伏度、坡度坡向;第三,遥感解译地层岩性构造,划分出泥石流敏感岩性及构造活动密集区;第四,遥感解译矿山活动信息,确定开发占地分类;最后,建立三维遥感场景,利用空间分析技术完成人机交互解译。陕西凤县实验结果表明,该方案针对性强、工作效率高,可以作为小范围大尺度矿山泥石流调查的技术手段。Based on the characteristics of mine debris flow,a remote sensing interpretation scheme for mine debris flow based on watershed division is proposed. Firstly,watershed area is divided based on digital elevation model;secondly,topographic relief and slope direction are extracted according to topographic and geomorphological factors;thirdly,strata lithologic structure is interpreted by remote sensing,and sensitive lithology and tectonic activity intensive areas are divided;fourthly,remote sensing. Interpretation of mine activity information and determination of development area classification. Finally,a three-dimensional remote sensing scene is built,and human-computer interaction interpretation is completed by using spatial analysis technology. The experimental results in Fengxian County,Shaanxi Province show that the scheme has strong pertinence and high efficiency,and can be used as a technical means for small-scale and large-scale mine debris flow investigation.
