水环境评价决策支持系统知识库系统的设计

水环境评价决策支持系统知识库系统是水环境影响评价决策支持系统的核心，通过系统知识库实现对数据库、模型库的统一管理和调度；辅助环境工作者做出正确的决策.在系统分析水环境影响评价领域知识特点的基础上，对水环境影响评价知识库的知识内容、知识的获取和知识的表示方法进行了初步的阐述，并提出了适合于该领域的知识表示方法和知识库体系结构.详细地论述了整个水环境影响评价知识库的设计思路和方法，并建立了水环境评价的推理机构.

Design and realization of knowledge base for environmental influence evaluation IDSS

Knowledge base system of water environmental influence evaluation IDSS is the core of decision support system(DSS) of water environmental influence evaluation.Data base and model base are managed and dispatched uniformly through knowledge base system,and thus operator is able to make the correct(decision.) Based on systemic analysis on knowledge characteristic of water environmental influence evaluation field,knowledge content,knowledge obtain and knowledge expression method in knowledge base are(described) primarily.Furthermore,suitable knowledge expression method and knowledge base system(structure) are proposed.Design idea and method of knowledge base of water environmental influence(evaluationis) are discussed,and reasoning mechanism of water environmental influence evaluation is established.
