Navigation Advantages of Three Gorges Dam

VIEWS: 3 PAGES: 3

									With the completion of Three Gorges Dam, it navigation advantage becomes more obvious. At the
same time, it also promoted the development of other industries.

Navigation Advantages of Three Gorges Dam

The construction standard of Three Gorges dam is to build world class dam. The power generation,
flood control and navigation benefits of Three Gorges Dam are becoming more and more obvious.
Navigation Advantages of Three Gorges Dam – Effect of Ship Locks
The industrial zone on the upstream of the Yangtze River has formed certain production capacity.
While the areas around the Three Gorges most are massifs. The most part waterway on the
upstream was in natural state, which is hard to pass by for ships in dry season. So the
transportation capacity is limited. The industry along the river is affected by transportation. The
inconvenience transportation also bring big problem to the port, waterway construction and
navigation mark management.
After the Three Gorges Dam completed, the water level in Three Gorges Reservoir will reach 156
meters. For the Three Gorges Reservoir area, with the increase of water level, the waterway will
become wider. With the increase of water level in main stream, the original stream or canaliculus
which flow out from some Tributaries become river, which increased the number of ferry on the
waterway. The tourism is the largest beneficiary, which will bring active effect to the employment
and “agriculture-countryside-farmer” problem in the reservoir area.
After a series of water impounding project, the waterway in the reservoir area will become deep
waterway in half a year. The water level in the waterway will increase 40 percents, while the width
will increase two times, and the flow rate of water will decrease 50 percents. It can meet the need
of ten thousand tons fleet to waterway depth.
Navigation Advantages of Three Gorges Dam – Inland River Navigation Condition
In many years ago, the shipping amount of the Yangtze River is about 60 percents of Rhine River,
Mississippi River and some other big rivers in the world. After several years’ construction, the
shipping amount of the Yangtze River has come into world class. Until the end 2005, the shipping
amount of the Yangtze River is the top one in the world.
Navigation Advantages of Three Gorges Dam – Requirement to Shipbuilding and Other Industries
With the completion of the ship locks in the Three Gorges Dam, the ships must be standardized.
Now, the small tonnage of ships and unorderly ship types are big problems which affected the
Yangtze River navigation development.
We can see from the inland river navigation development history that the waterway, port and ship
are three important factors in the navigation industry development. The ship is the most active,
vigorous and flexible factor. The development of new ship types while bring the usage and
generalization of new technology, new products and new material, which offer new market space to
the ship product industry and related industrials on the upstream.
In these two years, the number of Yangtze River navigation section and ships are reducing, while
and transportation amount are increasing. It proved that the efficiency o navigation is improving
with the standardization of ships.
三峡大坝的航运效益正在逐步显现

  专访交通部长江航务管理局局长金义华:———

  三峡水库即将开始 156 米蓄水,而配套的船闸完建工程已在上周启动,双线运行改为单线运行,
船闸通过能力将大为下降,这对长江水道的“黄成色”将带来怎样的改变?依赖长江航运的沿岸地区
如何减轻影响?

    《第一财经日报》近日专访了交通部长江航务管理局局长金义华。
  为此,

         :此次船闸完建施工结束后,将对长江上游、中游重要城市建设区域性航运中
  《第一财经日报》
心带来什么影响?

  金义华:长江中上游地区的产业带已形成相当的生产能力。而毗邻的三峡及周边区域山丘为主、
上游大多数通航河道一直处于天然状态,枯水期间大吨位船舶难以通行,运力有限,沿江产业受交
通因素影响,并给港口、航道建设和航标管理带来很大困难和资金成本。     此次完建后,库区水
位达到 156 米。对于三峡库区而言,水位提升,航道宽度随之扩大,干流水域逐步加深,其他支流
岔口从原来的小溪小沟成为小河,这样增加了航道渡船渡口的数量,旅游业首当其冲受益匪浅,对
库区就业、“三农”问题都将带来积极作用。

  一系列蓄水工程后, 库区航道将有半年时间成为深水航道,航道水深增加 40%,宽度增加 2 倍,
江水流速减缓 50%,可满足万吨级船队对航道尺度的要求。
  《第一财经日报》 :我国内河航运与先进国家相比存在一定差距,三峡工程一系列蓄水、船闸完
建工作后,与其他国家相比,我们处于怎样的位置?

  金义华:三峡大坝的建设标准是世界一流,对于发电、防洪、航运各方面带来的效益正在逐步
显现。目前和世界其他内河航运发达的国家相比,我国确实存在差距。

  6 年前,长江航运量仅为莱茵河、密西西比河等世界大型河流的约 60%。经过近几年的重视和
建设,长江运量迅速进入世界一流行列。截至 2005 年年底,长江运量已达世界第一。



  《第一财经日报》:随三峡船闸等航道硬件设施的不断完善,对于造船业等相关产业又会提出怎
样的新要求?

  金义华:随船闸完建施工的结束,船舶必须标准化。现在很多船型多年未变,船型杂乱、船舶
吨位小已成为困扰长江航运的一大问题。

  而从世界内河航运发展史借鉴,在决定内河航运事业的航道、港口和船舶三大基本要素中,船
舶是其中最积极、最活跃、最能动的要素。新船型的开发,将带动新技术、新产品和新材料的应用
和推广,为船舶制造业和上游相关产业提供了新的市场空间。

  这一两年,三峡航段及长江其他航段的船舶通过次数在减少,而运量在增加,说明航运的效率
随船舶标准化的推行在提高
