1. Natural factors:
The incoming channel should have sufficient depth and width; The plain topography is favorable to the equipment, buildings and urban layout of the port and Japan, and the channel of the port at the mouth of the river is often prone to siltation.
2. Economic, social and technological factors.
The influence of hinterland conditions and urban support is greater. The wider the hinterland and the more developed the economy, the more favorable it is for port construction. In addition, perfect supporting facilities and efficient operation services are also required.
3. Site selection principle.
River ports require rivers to be wide and deep, located in or close to cities, and places with convenient land transportation;
The seaport requires a leeward, wave-sheltered, deep bay with easy access to other traffic arteries.

The location factors of port construction include natural conditions and socio-economic conditions.
The natural conditions include water conditions and land conditions, among which the water conditions should meet the advantages of the port area, which has the advantages of wide water depth and small wind and waves; The land conditions should have a relatively wide flat land, which is conducive to the construction of ports and the stacking of port goods. In addition, natural conditions include temperature conditions (whether there is an ice age or not).
The larger the hinterland, the more developed the economy in the hinterland, and the larger the port; There is also the size of the port relying on the city, because the city can provide a lot of human, material and financial resources for the construction and development of the port; There is also the port's dredging capacity, that is, whether the port has convenient external transportation links.

1. Rationally lay out railway lines, improve the transportation network, 2. Promote economic ties and development between the two places, strengthen economic communication, and 3. Ease traffic.
Return pressure 4, promote.
Answer: The economic development along the route will form new economic growth points and drive the development ...... related industriesIt is both a location factor and a significance.
If you recall the location factor of the Beijing-Guangzhou Railway in high school textbooks, you can know.

The location factors of port construction include natural conditions and social and economic conditions.
Natural conditions have water.
Du domain zhi conditions and land domain strips.
Among them, the water conditions of DAO should meet the advantages of wide water depth and small wind and waves in the port area; The land conditions should have a relatively wide flat land, which is conducive to the construction of ports and the stacking of port goods. In addition, natural conditions include temperature conditions (whether there is an ice age or not).
The larger the hinterland, the more developed the economy in the hinterland, and the larger the port; There is also the size of the port relying on the city, because the city can provide a lot of human, material and financial resources for the construction and development of the port; There is also the port's dredging capacity, that is, whether the port has convenient external transportation links.

Location strip for port construction.
Bai piece: du
Natural conditions (determine the location of the port) zhi
1.Water strip dao piece: port wide water depth (depth contour dense special.
set, advantageously belonging to the mooring and shelter from the wind)
2.Port construction conditions: stable land geology, flat terrain, appropriate slope (conducive to the arrangement of building land, port equipment).
Socio-economic conditions (influencing the rise and fall of ports).
1.Conditions of the economic hinterland: whether the economic hinterland is vast (affecting the flow of passengers and goods); the size of passenger and cargo flows (affecting the rise and fall of ports); Hinterland economy.
2.Relying on the city: convenient transportation; Provide human, material and financial support for the port3Policy conditions: to build a free port in the area open to the outside world.

The sea water in the harbor should be deep enough. The wind and waves should be light throughout the year, preferably in the bay. I only think of these, the general direction, the first can be solved by land reclamation, such as Tianjin Port.

There are two types of conditions: natural conditions and socio-economic conditions. The natural conditions are mainly deep water, sheltered from the wind. The socio-economic conditions are: developed economy and convenient transportation.
-
1.The hinterland is vast. (The terrain is flat, the economic hinterland is wide).
2.The water is deep and the harbor is wide. (The port must be large, and the port must be deep to enter the big ship.) For example, Hong Kong's Victoria Harbour is better than Macau).
3.Convenient transportation. (Land railways, bridges, etc., to transport goods into the interior) and some necessary secondary.
The current can't be too fast, it can't freeze (ice-free harbor), it can't have too much silt (estuary).

A should be chosen, the coastal coast of Jiangsu Province is relatively straight, and there is a lack of excellent ports, which is not conducive to port construction (it is inconvenient for ships to enter and exit and berth).
If you have a double choice, choose AB, because C and D are obviously wrong, there are many high-level cities in Jiangsu Province (Nanjing, Wuxi, Suzhou, etc.), and the southern part of Jiangsu Province is located in the Yangtze River Delta, which is one of the most economically developed regions in the country, and the economic hinterland is vast.
I took the college entrance examination in 05, and I usually read books and read exercises. This is true of geography, but also of politics and history. At that time, I got a 230 out of 300, which was already a relatively high score in that year. >>>More
It's not that there isn't, but not for the time being.
It's so long to grow, no one can say. >>>More
It's a yes thing, but you're running out of time.
In math, most of them are textbooks, and they have to memorize formulas or something, which is beneficial, and in the future, when you see a big question in the exam, you should first press down the possible formulas. Definitely get a point. The rest pay more attention to the topics of geometry, trigonometric functions and probability, and strive to finish it, not to mention the simple ones, solid geometry can refer to the vector method, which may be relatively easy to understand. >>>More
GEI mailbox, send back to you. ok?
Each question is summarized by a large question answer Generally the answers to the big questions have rules The earth should be memorized In fact, my geography grades are very good, and there is no special learning method, but if you want to learn well, you should reach the point where the textbook is memorized like a stream Say a knowledge point, you can reflect where it is in the book What is the layout of that page For example, there is a ** knowledge point in that position Written in that paragraph, you should know in your mind what knowledge points are on that page in addition to that knowledge point Just reach this level Anyway, that's how I do, it's best to communicate with the teacher, ask the teacher to help, and I wish you a good grade.
