针对国家气象服务中心的实际要求，建立供各级公共气象服务中心开展公众气象服务调查、满意度调查使用的公共气象效益评估系统，提出了权限控制与区域关联，是基于区域权限的系统。不但需要实现权限控制，更重要的是对于不同级别用户，数据具有不同的可见性。实践证明，基于区域的权限控制访问技术，不仅能够使各级用户的管理更加自由灵活，同时也较大程度地提高了信息安全。Abstract: Aiming at the practical requirements of National Weather Service to establish assessment system of public weather efficiency for all levels of public weather services to carry out the survey of public weather services and satisfaction. The access control and regional association were proposed based on the regional authority system.
