摘　　要：探索通过数学模型和计算机仿真模拟的方法,分析推测影响鱼群群体空间分布的主要因子。初步研究结果表明,在视觉、游泳能力等诸因子中,鱼类的视觉能力,包括视距和视野对鱼群结构有重要影响,其中最大视觉能力范围是主要因素。该实验结果为实验观察提供了启示。可视化仿真结果与红鼻鱼群体录像资料的对比验证结果表明,采用IBMs理论建立数学模型,进行模拟研究的方法可行,仿真模拟的鱼群动态结果可以表现出与红鼻鱼群体实际运动相类似的分布状态。表明可视化仿真技术有助于对群体运动问题的探索和理解。This paper presents the methods for exploring fish schooling behavior by means of mathematical modeling and computer simulation,to explore and find out the major factors which have speculated influence on the space distribution of individuals in fish school. Preliminary findings indicated that among the factors of visibility and swimming ability etc.,the visual ability of fish,including sighting distance and perspective is the factor having stronger influence on the school structure,which provides some revelations or indications to the fish behaviour experiments design and observation. The comparison between the simulation and video records of Hemigrammus bleheri shows that the model based on IBMs theory is feasible,and the simulation results are similar to the actual movement of fish school,which indicates that the visual simulation technology helps better exploration and understanding on fish group motion.
