To Bao Feiyang's surprise, the debate at the forum was a bit fierce, in addition to the professor of Ocean University, there was also a reporter from the magazine, several people engaged in shipping, foreign trade and freight forwarding raised questions, and the most fierce opposition was a professor from Zhijiang University, who believed that Pujiang should abandon geographical divisions, carry forward the style of taking the lead, and choose to build a port in Ningcheng.

Ningcheng has very good waterway, port and shoreline resources, the water depth of the main channel of Ningcheng has reached 50 meters, and the water depth of the port area is 20 meters, which has very good conditions for the construction of deep-water port.

However, starting from the outermost Gaoqiao port area of the Pujiang River, it is also nearly 300 kilometers away from Ningcheng Port, and it takes about more than ten hours to sail from Ningcheng Port.

For enterprises, the cost must be considered, the development of the port industry, relying on the fast and convenient transportation and logistics of the port, if the deep-water port is built to Ningcheng, a large number of ocean freighter flights will choose to dock at Ningcheng Port, rather than Pujiang Port, then Pujiang local logistics can only go to Ningcheng Port for transit, some port industries may choose to build factories in Ningcheng.

The construction of the deep-water port in Ningcheng will not only affect Pujiang, but also the logistics and industrial pattern of the entire East China region. In addition to the logistics transported through Tianjiang Shipping has to take more than ten hours of voyage, as well as the resulting time and transportation costs, a large number of road logistics need to detour farther and spend more costs, which will inevitably lead to changes in the industrial pattern.

And not only that, ports, logistics also involves finance, international trade and other industries, on the one hand, Ningcheng does not have the corresponding supporting industries and service capabilities, on the other hand, if the relevant industries are really transferred to Ningcheng, then the relevant industries of Pujiang will be affected, Pujiang can have the current economic status and development degree, and Pujiang Port as the distribution center of foreign trade logistics in the Tianjiang Basin is inseparable, the distribution of logistics brings the distribution of trade, the distribution of funds, The distribution of people, without the port, does not have the status of the logistics distribution center of the Tianjiang Basin, the development of Pujiang City will definitely be greatly affected, so let Pujiang City carry forward the style, build the port to Ningcheng, and carry out the so-called integrated layout and development, which can only be wishful thinking on the part of Ningcheng and Zhijiang. It is impossible for Pujiang City to give up its economic status, and even the state cannot give up Pujiang as an economic center and instead support Ningcheng to replace Pujiang.

In addition to the Ningcheng Port plan, some people have proposed artificial reclamation projects in Tianjiangzui, Hengsha Island plan, Shuangqishan port construction plan, Sijiao port construction plan, etc., but these plans have their own advantages at the same time, they also have their own shortcomings, such as the Tianjiangzui reclamation plan and the Hengsha Island plan The amount of work is too large, the progress is too slow, The controllability is too poor, and the impact on the hydrological environment is relatively large, and at the same time of reclamation, it will cause the acceleration of sediment accumulation in the Tianjiang Estuary, which means that the Tianjiang waterway will be affected, and almost means that the existing Pujiang port area will be deposed.

The same is true for the Sijiao port plan, which connects the Sijiao port area with the mainland through a cross-sea embankment, and the sediment sedimentation caused by the embankment will form a large usable land area in the later stage, but it will also cause the sediment deposition in the Tianjiang waterway to be accelerated.

As for the Shuangqi Mountain scheme, the advantage of this scheme is that the islands have a larger land area but are farther away from the mainland, compared to the small Yangshan Islands, although the islands have a smaller land area, they are closer to the mainland.

However, the large and small Yangshan port area has only increased the range of less than 100 kilometers compared with the Gaoqiao port area, and it is connected to Huixun District through the sea-crossing bridge, which will still have a positive effect on Pujiang City.

The Ningcheng faction, the reclamation faction, and the outlying island faction spoke one after another, and their biggest criticism of dredging the Tianjiang waterway was that the dredging of the Tianjiang waterway was slow and the maintenance cost was high.

"The cement sand content of the Tianjiang River is high, and when the river water enters the sea, the sediment will be deposited when it encounters the top of the tide, forming barrage sand. According to the plan formulated by the relevant departments of the state, it will take 10 years and spend tens of billions of dollars, and only the main channel of the Yangtze River estuary can be dredged to a depth of 12.5 meters, which still does not meet the requirement of at least 15 meters of water depth in the deep-water port. Even so, due to the existence of barrage sand, the waters of the Tianjiang Estuary will continue to silt, and the water depth of 12.5 meters is difficult to maintain, and it is very uneconomical to invest huge sums of money every year to dredge and maintain the channel, and the construction of a deep-water port on the outlying islands can solve this problem once and for all......

"Professor Lu's words are ...... wrong"

The professor of Fenghu University immediately retorted: "Professor Lu has seen the advantages of building a deep-water port on the outlying islands, and it is true that through the construction of the deep-water port on the outlying islands, Pujiang Port can get a deep-water port area, but we should not forget why Pujiang Port can become the largest port in China? A very important reason is that Pujiang City is a special geographical location where rivers and seas meet, and bulk goods in the entire Tianjiang basin will be sent abroad through Pujiang Port, which has made Pujiang Port ...... today."

Pujiang Port has become the economic center and largest city in China, and Pujiang Port has become the largest port in China, which is of course inseparable from a large number of international trade logistics in the Tianjiang Basin. However, Pujiang's own industrial strength is also very strong, at the beginning of the reform and opening up, Pujiang's industrial output value accounted for almost a quarter of the country's total, and a large part of Pujiang's cargo throughput is local industrial products.

Of course, Pujiang itself has no natural resources, and Pujiang's industrial production also requires a large number of raw materials and spare parts from all over the country, and the Tianjiang River Basin, as the economic hinterland of Pujiang City, is indeed very important.

"The dredging of the Tianjiang waterway affects not only the route of Pujiang Port and international ocean-going freighters, according to the dredging plan of the Tianjiang waterway formulated by the state, not only the dredging depth of the waterway of the Tianjiang Estuary to 12.5, but also the dredging depth of the Tianjiang waterway below Fenghu Lake and Jinling, reaching a water depth of 7-10 meters, and the future can be dredged to a depth of 12.5 meters. The wharf of Jinling and the Tianjiang River will become a real golden waterway, which will play a huge role in the economic development of the cities along the river, which is not a substitute for the construction of a deep-water port on an outlying island!"

Cities and localities along the Tianjiang River are the hardcore supporters of the Tianjiang dredging program, the use of dredging programs, continue to expand the ports along the Tianjiang River, not only means that the international logistics transshipment of coastal cities saves hundreds of kilometers of voyage and the corresponding navigation time, with the dredging of the Tianjiang Estuary channel, the next step is to carry out the dredging of the lower reaches of the Tianjiang River, the overall water depth of the downstream channel in the future reaches more than 10 meters, and the cargo ships below 100,000 tons can be directly reached, which is very good for the port cities along the Tianjiang River.

Professor Chen Jingtian from Jinling University also said: "The Tianjiang flood caused huge losses the year before last, and the central government launched the water and soil treatment project in the Tianjiang River Basin. Soil and water conservation, soil erosion in the middle and upper reaches of the Tianjiang River will be improved, coupled with the adjustment of a series of barrage dams in the middle and upper reaches of the Tianjiang River, the sediment content of the middle and lower reaches of the Tianjiang River will be reduced, of course, considering the huge water flow of the Tianjiang River, there will still be more suspended sediment into the Tianjiang estuary, but the situation will be improved, and the cost of dredging and maintenance in the later stage will also be reduced......"

"In addition, although the dredging depth of the Tianjiang channel is mainly the dredging depth of the main channel, the overall dredging will be carried out, after the dredging depth, the depth increases, the water volume contained in the lower reaches of the Tianjiang River increases, and the water level decreases, which is also a major benefit to flood prevention and disaster reduction!"

"Therefore, the deep-water port of the outlying island only solves the deep-water port problem of Pujiang City, but the deep-water port of the Tianjiang waterway can not only solve the deep-water port problem of Pujiang City, but also solve the deep-water port problem of the major cities along the Tianjiang River, and will benefit a wider range of areas and cities along the coast......

Even if Bao Feiyang is determined to build a deep-water port on the outlying islands, he has to admit that the waterway of the deep Tianjiang River is also very necessary and reasonable.

In fact, Bao Feiyang is not opposed to the dredging of the Tianjiang waterway, the development of Pujiang City is inseparable from the development of cities along the Tianjiang River, the development of these cities will not take away the resources of Pujiang, a rapid development of the regional economy, will only make Pujiang City, as a regional leader, develop better.

In fact, this project began after the flood of '98, and the first phase of the project will be completed this year, and the overall Tianjiang estuary channel will be raised from 7 meters to 8.5 meters, mainly involving the section of the river below the city. The second phase of the project is to achieve the breakthrough of the 10-meter-deep waterway downstream and the 12.5-meter-deep waterway of the Tianjiang Estuary by 2005.

Bao Feiyang's view is that whether it is the dredging of the Tianjiang channel or the construction of Gaoqiao New Port, it is actually necessary, but it should not affect the construction of the deep-water port on the outlying islands. The construction of the deep-water port on the outlying islands is not only to solve the problem of whether Pujiang City has a deep-water port, but also means that Pujiang Port has the ambitious goal of competing for an international shipping and logistics transit center.

In the view of the ports along the river, the deep-water port of the outlying islands means that the voyage of the river-sea intermodal transport will increase by dozens of kilometers, and for international transshipment, the deep-water port of the outlying islands is closer to the international route, compared with the current Gaoqiao port, it saves dozens of kilometers of voyage and valuable time, therefore, for international ocean-going cargo ships, they prefer to berth at the deep-water port of the outlying islands outside the estuary, rather than the Gaoqiao port area in the estuary. The construction of a deep-water port on the outlying islands is more conducive to Pujiang Port to strive for the berthing of ocean-going cargo ships and the transshipment of international goods......
