公路景观管理决策支持系统

Decision Support System for Road Landscape Management Based on GIS Platform

基于GIS技术开发的公路景观管理决策支持系统是针对公路景观管理业务而开发的信息管理系统,系统采用地理信息系统(GIS)、专家系统(ES)以及数据库管理系统相结合的方法,建立了公路两侧自然本底数据、多媒体数据、评价指标因子、恢复方案等为主体的属性数据库;公路空间数据库;由专家知识及经验构成的知识库;相关的评价模型建立模型库和决策库;实现了多库统一的地理信息系统与专家系统相结合的决策支持系统。为公路景观管理部门对公路景观动态管理、评价公路自身及景观现状、制定恢复对策和措施提供了科学实用的管理手段。

Decision support system for road landscape management is an information management system developed based on GIS platform aiming at the road landscape management service. This system combines geographic information system （GIS）, expert system as well as database management system. It has established attribute database of natural background data of both sides of a road, spatial vector data, appraisal index factor, and recovery scheme as the main body of the database. Besides the attribute database, the system still includes road spatial database, knowledge database made up of the expert＇ s knowledge and experience, model base and decision-making database based on some correlated appraisal models. A decision-making support system with multi-database unification is realized, which provides some scientific and practical management means for the management departments in dynamic management of road landscape, appraisal of present situations of road and landscape, and establishment of recovery countermeasures.
