地方环境管理信息系统的系统分析

Systems Analysis of Regional Environmental Management Information System

系统分析是地方环境管理信息系统结构化设计的第一步,核心问题是要解决“做什么”。本文论述了系统分析的一般原则、管理职能的调查分析、系统功能分析、数据结构分析、数据流分析等基本内容和系统分析的主要方法。本文主张以功能为核心开展系统分析,这是地方环境管理信息系统取得成功和具有生命力的基本保证。

Systems analysis is in the first step of the structural design for Regional Environmmental Management Information System (REMIS). The core of the step is to settle the problem 'what has to do'. The paper decribes the general principles of systems analysis, the investigation of environmental management functions, the analysis of demands and the analysis of data construction and flow. An analytical method for REMIS has been suggested by stressing that systems analysis must face to the function demands of REMIS.
