下辽河平原多熟种植农业生态模式专家系统设计Ⅰ．系统设计思想

Expert system design for agroecological patterns of multiple cropping in Lower Reaches of Liaohe PlainⅠ.Design thought of the system

以下辽河平原为背景，以多熟种植农业生态模式为研究对象，描述了多熟种植农业生态模式在下辽河平原的实践，应用农业生态学原理，提出了多熟种植农业生态模式专家系统设计思想；运用专家系统、地理信息系统和关系数据库管理系统相集成的方法论述了系统总体结构设计原理．本文在理论上试图为应用现代计算机高新技术从事区域农业生态系统管理探索一条新路．

In this paper the practice of agroecological patterns of multiple cropping in the Lower Reaches of Liaohe Plain is described.The design thought of an expert system of agroecological patterns of multiple cropping is put forward by applying the principles of agroecology,and the design principles for overall structure of the system is described with the integrated approach of expert system(ES),geographic information system(GIS)and relational database management system(RDBMS).A new approach to the management of regional agroecosystems is theoretically explored by means of high and new technology of computer.
