The longest city in China, the main urban area is more than 100 kilometers long, and the narrowest part is less than 4 kilometers

China has a vast territory and many cities. Some urban planning is very similar, such as Beijing, Xi'an, Chengdu and other cities, the main urban area one ring plus one ring spread outwards. There are also some cities in the country, which are long and narrow belt cities. This type of city is mainly affected by the topography. For example, Baoji in Shaanxi is located in the Weihe canyon. It can only expand from east to west, and cannot build a city from north to south. There are many long and narrow cities like Baoji, and today we mainly introduce a veritable longest city in China. The main urban area of ​​the city is more than 100 kilometers long from east to west, and the narrowest point from north to south is less than 4 kilometers.

Lanzhou, the provincial capital of Gansu, ranks second in the ranking of cities in the northwest. This city is different from cities like Beijing, Xi'an, and Chengdu. It is not the kind that spreads and develops from the main urban area. It is more like a city like Baoji, Shaanxi. It develops on the basis of topography. The topography is like a horse's face, and the city develops for a long time. Among these "horse-faced" cities, Lanzhou can be called the longest city in the country. You want to ask me how long it is? I will tell you that it is very long~very long~ Just a joke, the main urban area of ​​Lanzhou is more than 100 kilometers long in the east-west direction, and the narrowest part in the north-south direction is less than four kilometers. Do you still think, this is not a cucumber!

Because Lanzhou is located in a very important geographical location in Gansu, it is very important to Gansu, so it is also called "Golden City" in history. Many people who are familiar with Lanzhou must be aware of the topography of Lanzhou. From Xigu District of Lanzhou to the west, there is Honggu District. This is the starting point of the west of Lanzhou, and the starting point of the east is around Sangyuanzixia in Chengguan District. If the measurement tool is used, it can be measured that the distance from the starting point on the east and west sides is about 100 kilometers. The narrowest point is around the Lanhua Farm in the north and south, which is less than 4 kilometers away. For other long and narrow cities, this is unique and irreplaceable.
