基于ES的植被景观多样性评价模型研究

介绍植被景观多样性评价模型的设计思想,然后进行构造其专家系统,该系统采用模块化程序设计技术,分为预处理、综合库、知识库、推理机、知识获取及知识管理和总菜单等6个模块,整个系统在主菜单控制下运行,各模块能独立运行。专家系统程序采用雄风专家系统开发平台VisualXF6.1,GIS由Arc/Info系统支撑。最后以永泰县为应用实例进行研究,创建永泰县植被景观多样性评价专家系统,对全县进行植被景观多样性评价,按景观多样性程度由高到低共评价5个等级,2243.4km2,评价结果与实际情况一致。

Study on the Evaluation Model of Diversified Forest Landscape Based on ES

This thesis introduces firstly the design of evaluation model of diversified forest landscape. Thus An elementary specialist system is constructed. This system is based on the technology of module programming. It is comprised of preprocessing, a synthesis base, a knowledge base, an inference engine, knowledge obtaining knowledge managing and total menu. The whole system is controlled by the total menu and various module can be run. This expert system is based on Visual XF6.1 and Arc/Info technology. Finally building the expert system of diversified forest landscape in is made with Yongtai county as an instance.
