空间辐射环境是航天器在轨运行所面临的重要环境要素之一，因其诱发的单粒子效应、总剂量效应、位移损伤效应、表面充放电效应、内带电效应等既可引起航天器材料、器件、结构等在轨损伤、性能退化甚至失效，然而又可以利用其开展空间育种等活动。文章从空间辐射环境与模型、空间辐射效应及机理、空间辐射环境与效应试验的评价标准、空间辐射环境效应试验方法、空间辐射环境与效应地面模拟试验设备、空间辐射环境与效应数值模拟、空间辐射环境与效应飞行试验及抗辐射加固技术等角度对空间辐射环境工程的现状进行了评述，进而提出了空间辐射环境工程各个领域的发展趋势。%Spacecraft in orbit is often in a critical space radiation environment, which will cause the property degradation or the invalidation of spacecraft materials and structures. The space radiation effects include the single event effect, the total ionizing dose, the displacement damage effect, the surface charging and discharging effect, and the internal charging effect. On the other hand, the environment can also be used for space breeding. The present states of the space radiation environment engineering are reviewed in this paper, which include the space radiation environments and their models, the space radiation mechanisms and effects, the standards, the testing methods, the ground simulation test facilities, the numerical simulation and the flight tests of space radiation environments and their effects, the radiation hardening technology and the space radiation bioengineering. At last, the developing trends of the space radiation environment engineering are commented.
