基于GIS的滑坡监测信息管理与分析系统

GIS-based management and analysis system for landslide monitoring information

滑坡监测的信息量非常庞大,而传统的滑坡监测信息管理系统都是基于关系型数据库的管理、查询和分析,处理空间信息就显得力不从心。采用MO(Map Objects)集成开发的基于GIS的滑坡监测信息管理与分析系统,把滑坡的空间信息和监测信息通过GIS技术联系起来,实现系统管理、快速查询和多种可视化分析。系统不依赖任何GIS平台,可独立运行,并可根据具体的滑坡和监测项目定制,保证了系统的通用性,为滑坡灾害研究提供了系统的工具。介绍了该系统的结构设计和实现方法,并以三峡库区泄滩滑坡为例,介绍了该系统的应用。

Landslide monitoring produces large amounts of data that can hardly be processed and analyzed manually. So an information management system is used for the management, search and analysis of monitored data. Traditionally the system is based on relation database (RDB) and can't be easily used for the processing of spatial information. The authors developed a GIS-based management and analysis system for landslide monitoring information with Map Objects (MO), which can integrate spatial and monitoring information of a landslide to implement functions as data management, search and multiple visual analysis. The system can also run independently and can be customized in accordance with particular landslide and its monitoring program, thus making it as a general tool for landslide research. In the paper, the structure design and implementation of the system are discussed; and then its application to Xietan landslide of the Three Gorges reservoir area is described.
