摘　　要：为高效、准确地实现对海岸线分形性质较为全面系统的分析,通过详细探讨海岸线分形计算系统集成方式、数据库设计以及结构和功能设计,选择Visual Basic为开发环境,采用Super Map Objects组件并结合分形函数计算模型开发分形计算系统.经过实例运行,结果表明:系统高效可靠,计算准确实用,可为海岸线分形性质的研究提供支持.In order to efficiently and accurately analysis the fractal nature of coastline, the fractal calculation system was developed by discussing its integrated approach, database design, structure and functions design using SuperMap Objects which was combined with the fractal calculation model in Visual Basic environment. After the example was operated, the resuhs show that the system is efficient, its computation is accurate, and it can provide the support to the fractal study of coastline.
