摘　　要：针对农产品质量安全认证这一关键问题,以无公害农产品产地认定与产品认证一体化工作流程为研究对象,从信息技术的角度构建了一个以实现认证流程的规范化和提高工作效率为目的的无公害农产品数字认证系统。通过对认证活动的分析,确立认证流程的两级节点域环境,构建节点域间中心化的分布式拓扑结构,设计分布式环境下的系统功能流程,探讨了关键技术;综合采用元数据、工作流和WebService技术,开发了面向申报者、检测机构和各级认证管理部门的分布式无公害农产品数字认证系统。系统提供了申报管理、认证工作流管理和认证信息资源服务等功能,实现了无公害农产品认证全流程、全方位的电子化管理。该系统在河南省和农业部试点应用,运行结果表明,达到了跨部门、跨地域的协同工作和认证信息的高效管理,具有较好的应用推广前景。Aiming at the key issue of agricultural product quality safety certification,the integrated workflow of origin cognizance and product certification of pollution-free agricultural products was studied so as to construct a digital certification system of pollution-free agricultural products from the perspective of information technology,with the aim of achieving normalization of the certification flow and improving working efficiency.Through the analysis of certification activities,the authors established the domain environment of two-level nodes of the certification flow, constructed centralized distributed topological structure among the node domains,designed system functions flow under the distributed environment,and discussed the key technologies;Declarer,detection mechanism and administrative departments at all levels oriented digital certification system of distributed pollution-free agricultural products was developed with the combined use of meta-data,workflow and Web Service technology.The system provides the functions of declaration management,certification workflow management,and certification information resource service to achieve the electronic management of full flow and orientation of pollution-free agricultural products certification. After pilot application in Henan Province and the Ministry of Agriculture,the results show that the system has achieved cross-sectoral and cross-boundary teamwork,as well as high efficient management of certification information,having a good prospect of application and popularization.
