摘　　要：地震信息系统在地震监测预报预警、地震灾害风险防控、地震应急响应与处置等方面发挥着重要的作用,但地震行业尚未建立完整的信息系统安全评价体系,且相关研究开展较少。为了更好地识别安全风险,提高地震信息网络安全防护能力,作者利用可拓方法建立信息系统评价模型,通过程序自动进行指标权重和关联度的计算,输出系统评价等级。实例表明:可拓方法可为地震信息系统安全评价、网络安全等级保护等提供支撑,并具有应用价值。本研究为评价指标的进一步优化调整,以及自动评价软件的完善和应用提供重要的基础。Seismic information systems play an important role in earthquake monitoring and forecasting,earthquake disaster risk prevention and control,and earthquake emergency response and disposal.However,there is not a complete information security evaluation system in the seismic industry,and the related studies are few.To better identify the security risks and improve the security protection ability of seismic information networks,in this study,an information system evaluation model was established by the extension method;the index weights and correlation degree were automatically calculated through a program,and the evaluation level of the system was obtained.The examples showed that the extension method can support the security evaluation of seismic information systems and the protection of the network security level and has application value.This study provides an important basis for the further optimization and adjustment of the evaluation indexes and the improvement and application of automatic evaluation software.
