Streets and alleys Text Ancient Chinese town roads.

History In the Han Dynasty, the main roads of the city were called streets, and the roads in the residential areas were alleys. The street character book refers to the road with four links. After the Warring States period, the roads in the square were called streets, and the roads in the square were called alleys.

In the middle of the street, there is the main road leading to the city gate, such as the "Eighth Street" of Chang'an City of Han Dynasty and the "Sixth Street" of Chang'an City of Tang Dynasty. In the Sui and Tang dynasties, the area of the square increased, and the cross road was opened in the square, which was called the cross street, and the branch road in the square was called the song. After the Song Dynasty, the city removed the fang wall and changed to the street and lane system, followed the square grid streets of the city with the Li Fang system, and transformed the square streets and curves into alleys with east-west orientation, so as to facilitate the construction of north-south residential buildings.

The alley can be directly connected to the main road, and the traffic is very convenient, but the large number of houses is dense, and there is no square wall to block it, and the fire is very easy to spread. At the beginning of the Southern Song Dynasty, it was stipulated that every 100 streets and alleys should be left with a one-zhang wide fire alley (or fire alley). The Yuan and Ming dynasties continued to use this road network.

The streets and alleys are still used as the names of the town's roads. Some cities in the south also call alleys (or alleys), and Beijing is mostly called hutongs. This road system of grid streets and east-west alleys was the main way of urban street layout after the Song Dynasty in China.

In addition, there are cities that form diagonal, circular, or radial road networks to adapt to the topography or to expand and renovate.

Width and structure The width of streets and lanes is graded by importance and traffic. "Examination Records" records that the width of Zhouwangcheng Street is calculated by the number of tracks, the width of the main road is nine tracks, and the width of Shuncheng Street is seven tracks. Tang Chang'an City Street is divided into nine levels, which are equivalent to meters, the width of the cross street in the square is about 15 meters, and the width of the alley is about 2 meters.

The main street of Han Chang'an City is divided into three roads, ** the royal road is about 20 meters wide, the road on both sides is about 12 meters wide, left in and right out, the middle interval drainage ditch, poplar trees are planted next to the road. Tang Chang'an City Street planted locust trees as street trees, and also built open ditches for drainage. The capitals of the Han and Tang dynasties are all dirt roads.

In some cities in the south of the Song Dynasty, brick pavement appeared. However, the capital street of Yuan Dadu is still a dirt road, and the stone ditch is drained. In the Ming and Qing dynasties, the city of Beijing was also a dirt road, and only some royal roads were paved with stone slabs; And by the open channel culvert and sewage river to form a huge rain drainage and sewage system, and the moat is connected.

According to the rules of the city of the Lifang system, only important government offices, temples and mansions can open the door to the main street on the square wall, so only the square gate, the square wall, the street tree and a small number of palaces and mansions can be seen on both sides of the street. The streetscape is neat and wide, but it is very monotonous. In the city with the street and lane system, shops and houses are set up along the streets, bell and drum towers are built at intersections, and archways are built across the streets (see the square table), and the roads are gradually encroached upon and narrowed, and the bustling street scene appears.

After the Han Dynasty until the Tang and Song dynasties, it was dominated by locust trees, and in the Ming and Qing dynasties, willow trees were the mainstay.

The tree planted on the street of Chang'an City in the Tang Dynasty is the locust tree, and the locust tree in Chang'an City has a history of thousands of years, which was planted in the early Sui Dynasty and has been planted in the Tang Dynasty.

Chang'an Avenue is an east-west axis of Beijing, named after the left gate of Chang'an and the right gate of Chang'an in the old days. East Chang'an Avenue is located in the southwest of Dongcheng District, Beijing, on the east side of Tiananmen Square, under the jurisdiction of the Donghuamen Street Office, is the east section of Beijing's famous "Ten Mile Long Street", in an east-west direction. It starts from the west end of Jianguomen Inner Street in the east, ends at the east side of Tiananmen Square and the National Museum of China in the west, communicates with Zhengyi Road, Taijichang Street and Chongwenmen Inner Street in the south, communicates with Nanchizi Street, Nanheyan Street, Wangfujing Street and Dongdan North Street in the north, borders the majestic Tiananmen Square in the west, has the National Museum of China in the south, and has the Working People's Cultural Palace in the north.

It's obviously a locust tree, don't believe it upstairs.

Smoke willow tree. Han Yu wrote such an article when he was an official in Chang'an.

In early spring, the water department was outside the eighteenth member.

The light rain in the sky street is as moist as a crisp, and the grass color is close but there is none.

It is the most beneficial spring of the year, and it is absolutely better than the smoke and willows in the imperial capital.

Translation] The fine spring rain on Chang'an Street is as lubricated as a crisp, and the regressive skin is not green up close, and the grass is green from a distance. The early spring of the closed boy is a good time of the year, which greatly beats the twilight spring when the city is full of willow smoke.

The street trees next to the streets of Chang'an in the Tang Dynasty continued the tradition of the Han Dynasty, and there were other tree species such as elm, willow, pine, cypress, camphor and some fruit trees, such as peach trees and plum trees. The main road is dominated by locust trees.

In Miyagi, the tree species are more mixed, but poplars and willows are still the main trees near the water, and the street trees are mostly willows and poplars by the water, and other places are common pines, cypresses, camphors, acacias, peaches and plums.

In this regard, some archaeologists have done relevant research, such as stipulating that only locust trees should be planted on Suzaku Street and elm trees should be removed. Because of its leafy branches and tall crown, the locust tree is suitable as a street tree.

The trees planted on both sides of the streets of Chang'an in the Tang Dynasty are, of course, willows. The willow tree is one of the oldest trees. But now many green belts don't use this kind of tree, because its catkins will have a little bit of an impact on people.

In the Tang Dynasty, the main trees on both sides of Chang'an Street belonged to camphor trees and plane trees.

In the Tang Dynasty, poplar trees were mainly planted on both sides of the streets.

The trees on both sides of Chang'an Street in the Tang Dynasty have incense sheets, and the precious trees of the same locust tree.

The question you asked, I guess no one has studied it yet, and there may not have been a species at all in ancient times, so you can study it as a topic.
