摘　　要： 提出了一个基于.NET的热带亚热带果树高产高效技术服务系统的总体架构,并对其功能模块和程序设计进行了详细描述,其中重点阐述了系统设计中推理机的设计、基于托管容器式持久性(CMP)数据访问方式的体系架构设计,权限分配策略、系统安全等关键技术。实践结果表明,CMP与传统数据访问方式相比使系统能增强功能、更加易于维护扩展,并且在数据结构变化时可以简单快速修改代码,最后总结了系统的特点。 A general structure of technological service system concerning the high yield and great efficiency of fruit trees in tropical and subtropical zone based on .NET platform is proposed, as well as description of its function module and program design is presented in detail. The illustration of the key technology for system design and its implementation is mainly discussed, such as the design of reasoning machine, the design of system structure for data access based on the container-managed persistence （CMP） mode, the authority assignment strategy and system safety technology. Compared with traditional approach, CMP is proved to be far easier for maintenance, expansion and upgrading, moreover, the codes can be easily and quickly altered when the data structure changed. In summary, the innovation and characteristics of the system is concluded.
