针对多来源、多格式、多尺度的区域火灾风险评估数据难于有效管理的问题,提出了一种基于GIS的区域火灾风险数据管理技术,即将火灾风险评估数据分为基础地理数据、规划数据、社会经济数据、消防业务数据和其他数据5类,在此基础上,构建了空间数据库、属性数据库和计算数据库3个数据库系统,并对空间数据库和属性数据库进行设计。该技术为火灾风险评估提供了较好的数据支持。
Aiming at the problem that multi-source, multi-format and multi-scale regional fire risk assessment data can not be effectively managed, a GIS-based regional fire risk data management technology is proposed. The fire risk assessment data is divided into basic geographic data, planning data, Economic data, firefighting business data and other data. On this basis, we constructed three database systems of spatial database, attribute database and computing database, and designed the spatial database and attribute database. This technology provides good data support for fire risk assessment.
