摘要
以川藏铁路沿线泥石流、滑坡、崩塌、溜砂坡等山地灾害的调查结果为基础,分析孕灾环境条件及山地灾害特征,开展面向服务的山地灾害综合数据库及信息平台开发方法研究。结合地理信息系统、遥感和数据库技术,构建川藏铁路山地灾害成灾环境数据库与灾害专题数据库,成功实现多源多维山地灾害信息的统一标准与有效管理。利用面向服务的COM组件式独立开发方法,建立基于ArcEngine的川藏铁路山地灾害数据管理系统,实现山地灾害的数据采集与质量控制、动态更新与空间检索、灾害评估与专题制图等,生成灾害数据开发产品,为铁路工程线路选定线设计以及制定减灾规划提供山地灾害基础信息支持,也为进一步建立交通干线工程数字减灾系统提供科学参考。
A service-oriented method to design and construct a database and information system for mountain hazards is proposed by analyzing the hazard environment and characteristics of debris flows,collapses,and landslides along the Sichuan-Tibet railway based on survey results.An integrated database of mountain hazards was designed and built by using Geographic Information System(GIS),Remote Sensing(RS)and database technology.Based on the ArcEngine technology of service-oriented COM component,the software platform of mountain hazards management was established to perform functions including input and update of mountain disaster data,query and analysis of mountain disasters,as well as dynamic hazard assessment and mapping.The disaster data products generated by this system will support the line selection and disaster mitigation planning of the Sichuan-Tibet Railway and provide scientific support for the further establishment of a digital disaster reduction system for traffic trunk lines.
