　　李盛霖指出，长江南京以下12.5米深水航道一期工程是贯彻国务院加快内河水运发展决策部署的重要举措，也是大力推进我国内河航道整治工程的重要举措。该工程是一个具有里程碑意义的内河航道整治工程，标志着我国内河航道建设进入了一个新的阶段。

Li shenglin pointed out that，Nanjing Yangtze river below 12.5 meters deep water channel a phase of the project is to carry out the state council to speed up the inland water transportation development decision deployment important action，Also vigorously promote our country inland waterway regulation engineering important action。The project is a landmark inland waterway regulation engineering，Marks the inland waterway construction in our country has entered a new stage。

　　李盛霖强调，长江南京以下12.5米深水航道工程，是一项建设周期长、技术要求高、施工难度大的重大工程。参建各方要重视工程质量、安全管理、科技创新和廉政风险防控，努力把这项工程打造成航道示范样板工程。

Li shenglin emphasize，Nanjing Yangtze river below 12.5 meters deep water channel engineering，Is a long construction period、High technical requirements、The major difficulty in construction engineering。Joining into the parties should attach importance to the engineering quality、Safety management、Science and technology innovation and the risk prevention and control，To make the project to create a channel demonstration pilot project。

　　长江南京以下12.5米深水航道建设工程是在长江口深水航道的基础上，将12.5米水深从太仓上延至南京，全长约280公里。工程建成后将实现长江口航道与南京以下深水航道无缝对接，五万吨级海轮可直达南京，第五和第六代大型远洋集装箱船和10万吨级散货船可乘潮通过。这将进一步发挥长江口深水航道的优势，大大提高下游海轮进江的运输能力，进一步提升长江国际航运功能，推动东、中、西部地区协调发展。

Nanjing Yangtze river below 12.5 meters deep water channel construction projects in the Yangtze estuary deepwater channel is based on，Will be 12.5 meters water depth on from taicang to nanjing，Total length of about 280 km。After the completion of the project will realize the Yangtze estuary channel and nanjing the deepwater channel seamless docking，Five - seacraft can go directly to nanjing，The fifth and sixth generation of large ocean container ship and DWT bulk carrier can take tide through。This will further play to the advantage of the Yangtze estuary deepwater channel，Greatly improve the ship into the river downstream of the transport capacity，To further enhance the Yangtze river international shipping function，Promote east、in、The western region coordinated development。

　　据介绍，长江南京以下12.5米深水航道建设工程将按照“整体规划，分期实施，自下而上，先通后畅”的思路，以“固滩，稳槽，导流，增深”为整治原则，采取整治与疏浚相结合的工程措施，拟分三期分步组织实施。

According to introducing，Nanjing Yangtze river below 12.5 meters deep water channel construction project will be in accordance with the“Overall planning，Phased implementation，bottom-up，After the first general chang”Train of thought，to“Solid beach，Stability tank，diversion，Increase deep”For the regulation principle，To take regulation and the combination of dredging engineering measures，Quasi three phase step implementation。

　　项目一期工程计划对太仓至南通河段约56公里的水道先行实施治理，实现太仓至南通河段航道水深达到12.5米的建设目标。工程总投资约51.7亿元，工期三年，计划在2015年年底前完成工程。二期工程将对南通至南京河段约224公里的水道实施治理，初步贯通南京以下12.5米深水航道。工程总投资约70至75亿元。二期工程争取在2013年年底前开工建设，2015年年底完成工程建设。三期工程将在“十二五”期后适时实施，进一步改善航道条件，全面建成南京以下12.5米深水航道。

The first phase project plan to taicang to nantong reach about 56 kilometers waterway anticipatory implementation management，Realize taicang to nantong river channel depth of 12.5 meters of construction goal。Project with a total investment of about 5.17 billion yuan，Time limit for a project for three years，The plan by the end of 2015 complete engineering。The second phase of the project will be to nantong to nanjing reach about 224 kilometers waterway implementation management，Preliminary through nanjing below 12.5 meters deep water channel。Project with a total investment of about 70 to 7.5 billion yuan。In the second phase of the project by the end of 2013 to start construction，By the end of 2015 complete engineering construction。Three phase of the project will be in“1025”After the implementation of phase timely，Further improve the channel condition，Comprehensive built nanjing below 12.5 meters deep water channel。

　　据了解，2011年5月18日建成投用的长江口12.5米深水航道，已经产生了巨大的经济和社会效益。根据相关研究，因运输费、中转费和中转损失减少产生的直接经济效益，在长江口12.5米深水航道开通的第一年就达到152亿元。长江南京以下12.5米深水航道建设工程建成后，将释放出更加显著的经济社会效益。

It is understood，On May 18, 2011 the revamping of the Yangtze river estuary is built in 12.5 meters deep water channel，Has produced great economic and social benefits。According to the related research，For transport、Transfer fee and transit loss reduction produce direct economic benefits，In the Yangtze estuary 12.5 meters deep water channel of the opening of the first year reached 15.2 billion yuan。Nanjing Yangtze river below 12.5 meters deep channel after the completion of construction projects，Will release more significant economic and social benefits。

　　以江苏省统计局的投入产出数据为基础，测算显示，工程实施后平均每年沿江港口吞吐量可递增约1.3亿吨，可直接拉动江苏沿江地区国内生产总值约238亿元，新增就业岗位约16.4万个；航道通过能力将提高一倍，可显著提高沿江港口效益、降低沿江企业物流成本，建成当年即可直接降低沿江企业物流成本23亿元；节能减排效果明显，每年可节约航运油耗21.6万吨，相应减少碳排放量约65万吨。

In jiangsu province bureau of input and output data as the foundation，Estimates show，After the implementation of an average annual along the river port throughput increasing can be about 130 million tons，Can directly pull along the Yangtze river in jiangsu province regional GDP of about 23.8 billion yuan，About 164000 new jobs；Channel through the skills will be doubled，Can significantly improve the harbors along the benefit、Reduce along the river enterprise logistics costs，Can be built directly reduce the riverside enterprise logistics cost 2.3 billion yuan；Energy conservation and emission reduction effect is obvious，Every year can save shipping oil consumption of 216000 tons，Corresponding to reduce carbon emissions by about 650000 tons。

　　长江干线是目前世界上运量最大、运输最繁忙的通航河流，2011年，长江干线货物承载量已达17亿吨。2011年1月21日，国务院颁布《关于加快长江等内河水运发展的意见》，提出利用10年左右时间，建成畅通、高效、平安、绿色的现代化内河水运体系，首次把加快长江等内河水运发展上升为国家战略。

The Yangtze river main is the world largest capacity、Transportation is the most busy navigable rivers，In 2011,，The Yangtze river main goods bearing capacity has reached 1.7 billion tons。On January 21, 2011，Issued by the state council《On speeding up the Yangtze river and inland water transportation development opinions》，This paper puts forward the 10 years or so，Built clear、efficient、peace、Green modernization inland water transportation system，The first to speed up the Yangtze river and inland water transportation development rise to national strategy。
