針對國家氣象服務中心的實際要求，建立供各級公共氣象服務中心開展公眾氣象服務調查、滿意度調查使用的公共氣象效益評估系統，提出了權限控制與區域關聯，是基于區域權限的系統。不但需要實現權限控制，更重要的是對于不同級別用戶，數據具有不同的可見性。實踐證明，基于區域的權限控制訪問技術，不僅能夠使各級用戶的管理更加自由靈活，同時也較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. It didn’t need to implement access control only， more important， the data had different visibility to different levels of users. Practice shows that region-based access control technology， not only can make the users at all levels of management more freedom and flexibility， but also can improve the information security effectively.
