宁夏牧草病害动态监控系统管理模式初探

PRELIMINARY STUDY ON THE SYSTEM MANAGEMENT MODEL OF FORAGE GRASS DISEASES IN NINGXIA

针对宁夏牧草病害的发生为害特点，提出了牧草病害动态监控系统管理的构想及具体实施办法。宁夏牧草病害是一个复杂大系统。它由标的子系统、管理指挥子系统和环境子系统组成，在管理上须采取定量和定性组结合的方法，以提高决策水平。在这一科学的管理方法中，管理指挥子系统是核心，它作为关键的主体工作系统，又分为信息子系统，决策子系统和行动子系统。在决策过程中可借助专家系统（ＥＳ）或者计算机辅助系统开展工作。

A conception of system management model is proposed,which based on the analysis of the change and the occurance ragularity of forage grass disease in Ningxia.The forage grass disease is a complex and big system.It includes aim subsystem,management subsystem and environment subsystem. The management subsystem is an important part of the disease system.Discussion are made in following subsystems such as dictate subsystem,expert subsystem and computer assistant subsystem.
