摘　　要：将专家系统、GIS有机结合,建立了基于GIS和专家系统集成的作物气候适应性评价系统。根据作物气候适应度,系统可创建作物气候适应性分区图。系统还引入了知识模型概念,建立了以知识模型为特征的知识库系统,并将空间数据库、关系数据库和知识库构建成三库一体,从而拓展了GIS系统功能。最后系统对江苏省小麦不同类型适应性进行了实例分析。图2,参12。On the basis of the integration of GIS and expert system, a system on crop climate adaptability evaluation was developed. According to crop climate adaptability degree, maps of crop climate adaptability division can be set up. The system has also introduced the model concept of knowledge, and established the knowledge base system based on knowledge model, and have spatial dat .abase, relation database and knowledge base become an organic whole, so GIS have been developed. Finally, the adaptability of there kinds of wheat in Jiangsu province was analyzed by this system.
