下辽河平原多熟种植农业生态模式知识库研建

BUILDING THE KNOWLEDGE BASE FOR THE AGRO ECOLOGICAL PATTERN OF MULTIPLE CROPPING IN THE LOWER LIAOHE PLAIN

本文以下辽河平原为背景，应用专家系统开发工具建立了多熟种植农业生态模式知识库，提出了建立该专家系统知识库的步骤：包括知识获取、知识表达、编码及证实。该专家系统知识库的建立能将有关多熟种植领域的专门知识和领域专家的经验以可接受的方式传递给农业决策者，从而提高农业决策的自动化和科学化。

In this paper, on the basis of the situation of the Lower Liaohe Plain, the knowledge base for the agroecological pattern of multiple cropping is built by using the expert system development tool. The procedures for building the knowledge base of expert system are put forward. They include knowledge acquisition, knowledge expression, making codes, and verification. The building of the knowledge base can transfer the expertise and the domain experts' experiences on multiple cropping to the agricultural policy makers in an acceptable fashion, thus improving the automation and scientism of agricultural policy making.
