灾害地貌专家系统试验研究

A TEST RESEARCH ON CALAMITOUS LANDFORM EXPERT SYSTEM

介绍了灾害地貌专家系统的建造原理与方法，阐述了灾害地貌专家知识的分类分级方法，讨论了灾害地貌专家系统中知识表示的基本原则和知识库中专家知识的组织方式，以及推理机的设计和推理规则的构造原理与方法。系统采用压缩编码方式存储各种地学专题图形和遥感图像数据，具有数据与图像的存储更新、查询检索、分析处理、图像显示和自动制图功能。该系统可以对灾害地貌过程进行专家级的预测和评价，并对灾害地貌的综合治理与区域规划提出几种可行性方案，供用户选择。用该系统对天山阿拉沟流域的泥石流灾害地貌进行了试验研究，并对试验结果进行了系统评价。

This paper presents the approaches and principles for building calamitous landform expert system (CLES). The author expounds the methods of classification and graduation for the expert knowledge of calamitous landform, discusses basic rules of knowledge expression in CLES and organization patterns of expert knowledge in knowledge base, elaborates design principles of inference engine (IE), and explains structural principles and approaches of inference rules. The system stores geo-thematic graphics data and image data of remote sensing(RS) in compressed coding. The CLES can be also used to store, update, inquire, search, analyse, process data and images, and to make maps automatically. In addition, the system can be used to predict and evaluate developmental processes of calamitous landform professionally. Moreover, several decision plans and regional programs can be obtained by consulting with the system, so that users can select a practicable one from them for comprehens)vely harnessing calamitous landform. Furthermore, the author makes a test research with the system on developmental process of debris flows in Alagou watershed of Tianshan Mountains, and evaluates the test results systematically.
