淮河流域行蓄洪区灾害损失评估数据库建设与数据更新

Establishment and data updating of flood damage assessment database system of Huaihe River basin

以GIS为设计工具,对淮河流域行蓄洪区灾害损失快速评估数据库建设进行设计,研究灾害损失评估数据库的数据采集、加工和更新。研究认为,行蓄洪区灾害损失数据库建设包括数据库内容、数据来源与处理、Geodatabase模型构建,以及数据库管理与整理等关键工作内容;数据库建设完成后的数据采集、加工和更新主体和路径要以淮河流域当前管理体制为依托,以淮河流域当前各项数据统计路径为载体进行。

As a design tool,GIS is taken to establish the flood damage quick assessment database system of flood detention zones of Huaihe River basin and to investigate its data collection,processing and updating. The results show that establishing the flood damage assessment database system of flood detention zones of Huaihe River basin mainly include the content of database,database source and processing, formulation of Geodatabase model as well as database management and sorting. Meanwhile,the database collection, processing and updating should be undertaken based on the current management system and various statistical paths of data in Huaihe River basin.
