摘　　要：为深入研究自组织聚集的微观机制,采用日本弓背蚁作实验材料,在二维正方形平面和二维圆形平面实验台上进行蚁群实验,通过高速摄像机视频跟踪并进行定量统计分析.实验结果表明,实验装置边缘对蚂蚁有"吸引"作用,随着群体规模增加,装置边缘对蚁群吸引减弱.通过研究蚂蚁速度,发现因为装置边缘的吸引,蚂蚁在边界和非边界运动状态不同.在边界,蚂蚁主要状态是"停止"和"低速运动";在非边界,蚂蚁主要状态是"低速运动".本文首次提出用层次社会熵定量测量蚁群聚集程度,发现其随着蚁群群体规模增加呈现先上升后下降趋势,表明蚁群聚集程度随着蚁群群体规模增加先下降后上升.Aggregation is one of the most common and important phenomena in natural world. Studying animal aggregation has been a challenging and has task attracted a wide range of scientists. In order to further study the regulation of the self-organization of an ant group, we observe the behaviour of Camponotus jam ponicus on a square area and a circular area. High-speed camera was used to track ant positions, quantitative statistics was then conducted. It was found that the experimental platform edge had particular ＂attraction＂ for the ants. Attraction of platform edge tended to decrease with increasing group size. The study of velocity showed that ants tended to stop or move slowly near the wall and tended to move slowly far from the wall. Hierarchical social entropy was used to measure aggregation degree. The social entropy was found to increase initially then decrease with gradual increase in group size, indicating that increase in group size resulted in ant aggregation degree to first decrease and then increase.
