摘　　要：文中旨在探索一种较为客观、便捷的扫描电子显微镜图像处理方法,以减少人为干预的主观性。通过使用CoreDRAW以及ArcGIS中相关的空间分析工具,对SEM图像进行处理,并利用导出的数据证明黄土颗粒的一些微观特性:土颗粒的数量随深度的增加而逐步增多,颗粒的椭圆率和离散系数越来越小,圆形度和分形维数则具有增加的趋势,方向角变化不大。此方法不仅提高处理SEM图像的速度和便捷性,且增强分析的客观性,有效揭示黄土颗粒的微观结构特性,为黄土微观结构研究提供了新的技术手段。The purpose of manuscript is to explore a more objective and convenient Scanning Electron Microscope(SEM)image processing method to reduce subjectivity.By employing CoreDRAW and related spatial analysis tools in ArcGIS,the SEM images are processed,and the derived data prove some microscopic characteristics of loess particles:the number of loess particles gradually increases with depth,the ellipticity and dispersion coefficient of the particles decrease,while the circularity and fractal dimension show an increasing trend,and the direction angle does not change significantly.This method not only enhances the speed and convenience of processing SEM images but also increases the objectivity of the analysis,effectively revealing the microscopic structural characteristics of loess particles and providing new technical means for the study of loess microstructure.
