新华社武汉８月２４日电（记者 田建军）记者从交通运输部长江航道管理局获悉，贯通长江２０００多公里干线航道的长江电子航道图（２．０版）近日圆满研发制作完成，成功实现系统升级，这意味着我国长江“数字航道”和“智能航道”建设迈上了一个新台阶。

    Xinhua news agency on August 24, wuhan（Reporter y）Reporters from the traffic department of transportation the Yangtze river waterway bureau，Through the Yangtze river 2000 kilometers main channel of the Yangtze river electronic navigation channel chart（Version 2.0）Recently a complete research and development production，The successful implementation system upgrade，This means that our country Yangtze river“Digital channel”and“Intelligent channel”Step on the construction of a new stage。

    所谓“电子航道图”，通俗地讲就是传统纸质航道图的数字化，以数字化形式直观准确地展现长江及两岸地物要素的数字地图产品。近年来，随着长江水运的飞速发展，传统的纸质航行参考图由于更新周期长，航道、航标信息不能及时有效更新，已不能完全满足船舶航行要求。长江电子航道图通过数字化形式及时更新，为长江上的行轮提供准确的助航标志、水深数据、地物地貌等航行信息，设计最佳航线并保证其安全航行。

    The so-called“Electronic navigation channel chart”，Generally speaking is the traditional paper channel map digitization，In digital form intuitive accurately show the Yangtze river and the feature elements of the digital map products。In recent years，With the rapid development of the Yangtze river water transportation，The traditional paper navigation reference due to update cycle is long，channel、Beacon information can't timely and effective update，Have been unable to fully meet the requirements of ship navigation。The Yangtze river electronic navigation channel chart through the digital form update，For the Yangtze river on the road wheel provide accurate navigation marks、Depth data、Physiognomy and navigation information，The optimal design of the route and guarantee the safe navigation。

    长江电子航道图的研制始于２００７年，２００８年我国第一段数字航道——全长３６９．５公里的长江下游南（京）浏（河口）段数字航道全面建成并投入使用，２００９年长江干线２６８７．８公里航道的电子航道图全线贯通，２０１１年１２月２２日正式投入使用。

    The Yangtze river electronic navigation channel chart research began in 2007，In 2008, the first paragraph digital channel - 369.5 km south of the Yangtze river downstream（Beijing）clear（estuary）Period of digital waterway comprehensive built and put into use，In 2009, the Yangtze river main 2687.8 kilometers waterway electronic channel map all through，On December 22, 2011 formally put into use。

    据长江航道局局长熊学斌介绍，长江电子航道图（２．０版）是对此前已经投入使用半年多的长江电子航道图的一次系统升级，共涉及产品文件４１６幅，其中全线索引图９幅，水道详情图３４４幅，整个航道图的生产制作历时７个月时间。

    According to the Yangtze river hydrographic department director XiongXueBin is introduced，The Yangtze river electronic navigation channel chart（Version 2.0）Is to have already been put into use after more than half a year of the Yangtze river electronic navigation channel chart a system upgrade，A total of 416 pictures in product documentation，The index of all figure 9，Channel details diagram 344 picture，The whole channel map production lasted seven months time。

    熊学斌说，长江电子航道图具有国际通用性强、定位精度高、航道信息内容丰富等特点，具备自动识别与定位、导航与辅助决策、自动匹配与显示应用、航道信息动态查询与显示和航行报警提示等五大功能。长江电子航道图（２．０版）的研制成功，进一步提高了长江黄金水道的科技含量和内河航运信息化水平。

    XiongXueBin said，The Yangtze river electronic navigation channel chart with international universality、Positioning accuracy high、Channel information rich content etc，Possesses automatic identification and positioning、Navigation and auxiliary decision-making、Automatic matching and display application、Channel information dynamic query and display and navigation alarm prompt five functions, etc。The Yangtze river electronic navigation channel chart（Version 2.0）The successful development of，Further improve the technological content of the gold waterway of the changjiang river and inland waterway informationization level。

    据悉，长江电子航道图（２．０版）将于１０月１日正式投入试运行。

    It is reported，The Yangtze river electronic navigation channel chart（Version 2.0）Will be held on October 1, officially put into operation。
