在多种评估模型和方法研究的基础上，利用计算机技术、网络通信技术以及数据库技术，研究了气候异常对国民经济影响的综合业务评估系统的总体技术方法，介绍了系统的总体框架、工作原理和软硬件运行环境。进一步给出了气候影响评估基本业务流程和子系统的主要功能，初步建立并实现了气候异常对国民经济影响的综合业务评估系统。

On the bases of studying on many assessment models and methods, we study the whole technique and method of synthetic operational assessment system of climatic abnormality impacting on national economy by means of the computer technique, network communication technique and database technique. We also introduce the whole framework of the system, work principle and software/ hardware running environment, further show out the basic operational flow process about climate impact assessment system and main functions of subsystems, including data received and cured subsystem, synthetic information query subsystem, climate impact assessment models analysis subsystem, models of agriculture, water resources and other aspects of national economy are involved, countermeasure integration assessment subsystem and monthly, seasonal, annual climate impact synthetic assessment subsystem. At last, we initially found and achieve the synthetic operational assessment system of climatic abnormality impacting on national economy.
