摘　　要：人类生产力发展已经进入算力时期,计算能力将成为这个时期的新型生产力。未来大量分散化的算力、存储等资源分布在空间信息网络中,需要对其进行整合拉通,为业务提供便捷的按需使用。首先从下一代空间科学任务出发,阐述了未来空间分散计算实施的意义和价值,同时从空间信息网络和地面信息网络两个维度对国内外典型的分散计算项目和框架进行了系统调研。在此基础上,从云环境构建、云-边中间件以及边环境构建3个方面详细阐述了空间分散计算模拟验证系统的构建思路与方法,并进行了试验验证。验证结果表明,该系统能够实现虚拟化计算单元的动态部署与更新,且能够实现高效的舰船目标检测。相比于单星检测而言,系统通过多星联合的方式能够将检测效率提升4.5倍。The development of human productivity has entered the period of computing power.In the future,a large number of decentralized computing power,storage and other resources will be distributed in the space information network,which needs to be integrated to provide on-demand use for service.Firstly,starting from the next generation space science task,this paper expounds the significance of the implementation of space dispersed computing in the future,and systematically investigates the typical dispersed computing projects and frameworks at home and abroad from the two dimensions of space information network and ground information network.On this basis,the construction method of space dispersed computing simulation verification system is described in detail from three aspects:Cloud environment construction,cloud-edge middleware and edge environment construction.Moreover,the experimental verification is carried out.The results show that the system can realize the dynamic deployment and updating of virtual computing units,and can achieve efficient ship target detection.Compared with single satellite detection,the system can improve the detection efficiency by 4.5 times through the computing power combination of multiple satellites.
