摘　　要：首次将ImageJ图像处理软件应用到泥石流固体颗粒的分析中,通过对固体颗粒边缘的识别,实现对沟道粗化层块石粒径的快速自动提取.以白龙江流域构林坪泥石流沟为例,使用该软件对构林坪沟沟道固体颗粒粒径和圆度进行计算,并对提取结果进行检验,结果表明ImageJ软件对固体颗粒粒径及圆度提取效果较好,可以为泥石流基础数据勘察提供新的技术与支持.ImageJ software was first applied herr to analyzing debris flow, and the extraction of the particle size of solid grains was automatically achieved by recognizing the edge of the solid grains. The software was used to construct the practical size and circularity of solid grains in Gou Lin-ping gully, Bai Long River, as an example. And the results were analyzed in detail, which showed that the effect of the extraction of the practical size and circularity of solid grains was good. This can provide a new technique and support for the survey of basic data in debris flows.
