说明：  以航标、测绘和通信为主的三大板块，是我国水上交通安全保障体系的重要组成部分，承担 着船舶航行的技术支持和航运经济的服务保障职能，对我国水上交通安全形势的持续稳定发挥了 不可替代的重要作用。从上世纪七、八十年代起，随着我国水上交通安全监督体制改革的逐步深 入，航标、测绘、通信等机构先后经历了数次体制改革、机构变化和职责调整，逐步建立了具有 中国特色的航海保障体系。 (To buoy, mapping and communication of the three main sections, is an important part of water transportation security system, technical support and bear the shipping service guarantee economic functions of the ship sailing on a steady water traffic safety situation in our country to play an irreplaceable important role. From the 1970s, since the 1980s, with the gradual deepening of China' s reform of water traffic safety supervision, aids to navigation, mapping, communications and other institutions have experienced several reforms, institutional change and responsibilities adjustment, gradually established with Chinese characteristics maritime security system.)
