三峡库区地质灾害防治信息系统及预警指挥系统数据管理模式探讨

Discussion on the data management mode of geologic disaster prevention and control information system and early warning command system in the Three Gorges Reservoir Area

三峡库区地质灾害的原始数据是一种多来源、大数量、多类型、多格式、多尺度、多参照系、多精度、标准化程度差、数字化程度不同、密级不同的多源异构大数据,采用单一数据库对数据进行管理的模式无法满足不同层次数据管理、不同层次数据应用的实际需求。依据三峡库区地质灾害数据的本身特征和多层次数据应用的需求,本文采用了一种双层四块、底层物理隔离的数据管理模式。这种模式支撑了三峡库区地质灾害防治信息系统及预警指挥系统几年来的顺利运转,不但很好地管理了三峡库区多年来的各类涉密与非密的原始数据和成果数据,也可以为不同层次的管理部门和科研等部门提供多层次的数据支持与服务,是一种针对部分涉密的复杂大数据的良好的管理模式。

The original data of geological disaster in the Three Gorges Reservoir Area is a kind of multi-source heterogeneous data.This kind of Big Data is multi-source,with large quantity,multi-type,multi-format,multi-scale,multi-frame of reference,multi-precision,with poor standardization,different degrees of digitization,as well as different security classifications.The mode of managing the data with a single database cannot meet the actual requirement of different levels of data management and data application.According to the characteristics of geologic disaster data and the demand of multi-level data application in the Three Gorges Reservoir Area,we adopted a data management mode of double layers-four pieces,and the underlying physical isolation.This mode has supported the successful operation of the geologic disaster prevention and control information system as well as the early warning command system in the Three Gorges Reservoir Area for several years.It can not only manage all kinds of classified or unclassified raw data and result data in the Three Gorges Reservoir Area,but also provide multi-level data support and service for management departments and research departments at different levels.It is a useful management mode for the partly classified and complex Big Data.
