Briefly describe the convenient water and land transportation conditions in Shanghai, Nanjing and Ha

1. There are many rivers such as the Yangtze River in the area, and shipping is convenient.

2. There are many ports along the Yangtze River, and Shanghai is a seaport, which can expand overseas markets, facilitate distribution logistics, and facilitate shipping.

3. There are many railway lines in the region, such as Shanghai-Nanjing, Shanghai-Hangzhou, Nanjing-Hangzhou Railway, etc., and there are Shanghai-Nanjing intercity railways and Shanghai-Nanjing high-speed railways under construction, with convenient railway transportation.

4. The highway construction is mature and the transportation is convenient.

5.On the eastern coast, the tertiary industry is developed and the funds are abundant.

Most people want to arrive as soon as possible, so long-distance travel is mostly by plane or train, and close to car Sometimes in order to enjoy the scenery on both sides of the river, there are also special tourist boats Freight should be selected according to the nature, quantity, transportation distance, timeliness, etcLive animals or fresh goods that are easy to die and deteriorate can be transported by road for a short distance, and special cars on the railway can be used for long distances and in large quantitiesBulky and bulky goods, transported over long distances, and transported by water or rail as much as possible Therefore, 10,000 tons of sea salt were transported from Tianjin's Changlu Salt Farm to Shanghai by sea Two boxes of H7N9 avian influenza vaccine were transported from Beijing to Guangzhou by air 500 tons of steel were transported from Baotou to Urumqi by rail 10,000 tons of rice were transported from Wuhan to Nanjing by river

Therefore, a

Therefore, a

10,000 tons of sea salt from Tianjin to Shanghai, suitable for sea transportation, a ton of live fish from Xiantao to Tianmen City, suitable for road transportation, Urumqi railway station violent terrorist incident a seriously injured people urgently need to be transferred to Shanghai for surgery, suitable for air transportation, 100,000 tons of rice from Wuhan to Shanghai, suitable for river transportation, Xinjiang natural gas ** Shanghai, choose pipeline transportation

Therefore, b

The water transport volume is large, the freight rate is low, but the speed is slow, limited by the region, suitable for the long-distance transportation of large volume between the two seaports, so it is reasonable;

Road transport is flexible and can be from door to door, moderate, suitable for short-distance transportation, so it is unreasonable;

Air transport is fast, but the volume is small, high, suitable for long-distance transportation in urgent situations, so reasonable;

Road transport is flexible and can be from door to door, moderate, suitable for short-distance transportation, so it is unreasonable;

Therefore, b
