摘要
本文描述了褐飞虱治理的决策过程、决策所需信息及计算机系统的结构和功能。该系统由数据库、模型库、决策分析和使用说明四部份组成。数据库可用于贮存和查询有关褐飞虱迁入量、气温、发生期和发生量、种群动态、临近地区历年发生情况、生态学特性及农药方面的资料。模型库包括可用于预测发生期、发生量、为害程度和种群动态的四个模型,决策分析学系统包括决策分析模型和专家系统。系统综合了数据库、模拟模型和专家系统的特点,为支持和改善褐飞虱治理的决策提供了一种实用工具。
Description was given regarding the decision making process in BPH management, information for decision making and structure and function of a base, decision analysis and help. The data base can be used to store and access information related to immigrants, temperature, emergence time and size, population dynamics, data from neibousing couties, ecological characteristics and pesticides. The model base consists 4 models which are useful for predicting peak time, peak size, yield loss and population dynamics in crop seasons. The decision analysis subsystem is composed of a decision analysis model and an expert system. Having combined the attributes of a data base, and simulation modelling and an expert system, the computer system provides a practical tool for supporting improving the decision making for BPH management.
