泥石流危险度评价的GIS与专家系统集成方法研究

针对泥石流灾害的特点，提出了泥石流危险度评价的系统集成策略。即泥石流危险度评价集地理信息系统和专家系统为一体，采用公共接口模块的外连式结构进行集成，并具有较好的用户界面和构造特定的应用框架为用户导航，实施的中心环节是组分软件的优选、各组分间转换、访问函数的实现和特定应用框架的构造。通过建立孙胡沟流域的数据库和泥石流危险度评价的知识库，利用集成系统对孙胡沟流域泥石流危险度进行了评价。

Study on Integration Methods of GIS and Expert System for Mudflow Hazard Assessment

In accordance with the specific characteristics of disaster restilted from mudflow and present conditions, the system integration strategy for assessment of mudflow disasters was proposed. The integration system for assessment of mudflow disasters was configured with externally linkage architecture based on the common interface medule and included two components, i.e. GIS and expert system. Thus central link of implementing the integrated system is construction of transformation function, accessing function and specific application frameworks. Transformation functions and accessing functions were performed as Dynamic Link Library so as to be shared by application programs. Application frameworks were expressed by Stepwise Input-Processing-Output graph (SIPO) and constructed by program manager and Multi-Document editor with OLE interface. After database on the Sunhugou watershed and knowledge base for mudflow hazard assessmeht were built up, mudflow hazard on the Sunhugou watershed has been assessed in this paper. Through comparison between field investigation and distribution map for mudflow hazard outputed by the integrated system the result shows that the integrated system is operable and highly reliable.
