摘　　要：为解决气象信息系统中多套存储设备挂载和管理不便的问题,实现后端存储在前端应用的统一文件目录和数据安全分级管理,引入数据湖技术,搭建了统一的虚拟文件系统,对虚拟文件目录与后端存储数据文件进行有序规划和映射,并利用用户分组和目录授权达到对用户访问气象文件数据的分级管理,有效提高了气象数据的安全管控能力,为气象文件数据的服务应用和气象数据挖掘分析提供了便利。In order to solve the problem of inconvenient mounting and management of multiple sets of storage devices in the meteorological information system,realize the unified file directory and data security hierarchical management of back-end storage in front-end applications,this paper introduces the data lake technology,builds a unified virtual file system,and orderly plans and maps the virtual file directory and back-end storage data files.The user grouping and directory authorization are used to achieve the hierarchical management of users’ access to meteorological file data.It effectively improves the security control ability of meteorological data,and provides convenience for the service application of meteorological file data and meteorological data mining and analysis.
