Let street trees develop and grow together with the city

　　"Flying from the south of the Yangtze River to the southwest, the street trees on both sides of the city have also changed from sycamores to palms." "There is rain in the warm air of the small town. The smell of camphor trees is my nostalgia"... City street trees are not only a pleasing urban landscape , but also a city business card representing the characteristic style, with the humanistic feelings imprinted by time.

　　Recently, this newspaper has received many letters from readers offering advice on planting and managing urban streets. The reporter also went to many places to interview landscaping workers, citizens, experts and scholars.

Everyone said that they should attach importance to the landscape and historical and humanistic value of urban street trees, scientific planning, fine management, and resonance with urban development, and become a good memory for citizens.

"One road, one tree" and "one street, one scene" make cities unique and unique

　　Yang Xuanyi, a reader in Wuhan, wrote in a letter a few days ago, saying that some time ago, he saw a camphor tree that was growing well on both sides of the road, and it was suddenly dug up for some unknown reason.

"It is recommended to combine street trees with urban garden construction. One road has the characteristics of the other, and the other street has the beauty of the street." Yang Xuanyi said.

　　In recent years, urban street trees have received extensive attention.

There are often complaints from readers and netizens that the road has been repaired but no greenery is seen, or that the street trees have suddenly disappeared for many years.

People not only pay attention to whether the street tree is alive or not, but also hope that the tree can bring shade and become an ecological landscape that can be seen from the head.

Nowadays, many cities regard street trees as an important part of urban construction, and plan and design them carefully.

　　Datong, Shanxi is one of the first batch of national historical and cultural cities.

The reporter recently came to the ancient city wall of Pingcheng District. Song Li, the captain of the ancient city of landscaping and maintenance, told the reporter: "Datong is dry and lacks water, and the selection of evergreen trees is limited. Although some plants are well-shaped, they are difficult to manage and protect, and are prone to pests and diseases. It is not easy to survive. In recent years, we have tried our best to choose evergreen trees, especially the landscape pines, which have a different mood after snow in winter.”

　　"With the continuous development of the city, the idea of ​​planting and maintaining street trees should also keep pace with the times." said Ren Shuai, director of the Datong Landscaping Center. More than ten years ago, Datong street trees were mostly a single tree species. In recent years, a number of road greening projects have been implemented. , On the basis of the extensive selection of native trees, some new varieties have also been introduced. After more than ten years of cultivation, the trees have become shady.

Today's Datong, Chinese locust, Chinese pine, ash, Yuanbao maple, spruce, etc. are lush, lilac, luan branch, golden leaf elm, forsythia, all kinds of ornamental begonias, etc. are graceful, "Spring has hundreds of flowers and autumn fruits, summer has green shade and winter. Looking at the pine", the layered flora makes Datong colorful in the four seasons, and also adds a green memory to the citizens.

　　In Badaguan Scenic Area, Qingdao, Shandong, the cypresses on both sides of Linhuaiguan Road are green and green, forming a green corridor.

Wei Zhiqing is a native of Qingdao, and he is very familiar with the street trees of "Badaguan": "Beach on Shaoguan Road is the best in spring, the maple leaves on Jiayuguan Road are in red in autumn, and the cedar on Zijingguan Road in winter is accompanied by white snow, which makes people linger. There are also begonias on Ningwuguan Road, ginkgo trees on Juyongguan Road, and French sycamore trees on Shanhaiguan Road. The trees on each road are different and each has its own beauty.”

　　"Rows of historical buildings and rows of luxuriant street trees will give visitors a wonderful feeling of traveling through history. This is the unique heritage of Badaguan Scenic Area, which attracts more and more tourists to visit and play. " said Zhang Chao, deputy director of the management and service center of Badaguan Scenic Area, Qingdao Seaside Scenic Area.

　　This summer, the city of Kunming, Yunnan held the Jacaranda Cultural Festival, and the protagonist Jacaranda is the street tree.

Jiaochang Middle Road in Wuhua District has the most distinctive Jacaranda landscape road. Every time when the flowers are in full bloom, the whole road looks like a river of blue and purple flowers, and many tourists come here to check in.

According to Meng Ruidong, deputy director of the Greening Department of Wuhua District, it was an unintentional act of jacaranda to become an "Internet celebrity" attraction, "This tree species was introduced in the 1980s, and it is loved by people because of its dense flowers and gorgeous colors. The city of Kunming also regards jacaranda as one of the tree species on the street to create 'one road, one scene'. At present, more than 18,000 jacaranda trees have been planted in the main urban area of ​​Kunming, which has become a beautiful business card."

Keep the "trees with stories" and let the city's memory be passed down from generation to generation

　　A Henan netizen left a message on People's Daily Online's "Leadership Message Board", saying that the trees on the roadside of Lao Xubi in Wugang City had been cut down for some reason. cut it?"

　　A letter from Zhuang Yongming, a reader in Jiaxing City, Zhejiang Province, stated that in some places, in order to widen the roads, street trees that had been planted for decades were cut down; in some places, camphor trees with a diameter of several tens of centimeters were transplanted elsewhere. Due to lack of management, they soon died. most of the time.

Street trees are valuable public resources. It is recommended that relevant departments make long-term planning, fully consider the value of street trees in various project constructions, and do a good job in protection.

　　In Baoding City, Hebei Province, Chinese locust has a long history, some of which are hundreds of years old. Citizens affectionately call it "Longevity Tree" and "Happiness Tree". Chinese locust has also become a cultural landscape and historical symbol of Baoding. .

Chen Shuangtian, a reader in Baoding, wrote in his letter: "Street trees often take several years or even a dozen years to cultivate before they become mature. However, in some cities, they are dug up and replanted after only a few years or even less than a year. What about becoming a city card?"

　　For many citizens, a street tree is not only a tree, but also a sustenance of feelings.

Some street trees are also closely related to the city's history, and "trees with stories" are also an important carrier of citizens' memories.

Meishan, Sichuan is the hometown of Su Dongpo, a great writer in the Song Dynasty. Relevant departments selected crape myrtle, begonia, wood hibiscus, etc. suitable as street trees from Su Dongpo's poems and songs, and made it into a cultural symbol street scene of Dongpo.

Yu Yongzhong, director of the Meishan City Landscaping Service Center, said: "The lush street trees complement the poems that Su Dongpo has recited so far. The citizens feel the beauty of street trees because of the poems, and they remember Su Dongpo's poems because of the street trees."

　　Planting and managing street trees requires scientific management and meticulous work.

In Qingdao, Hunan Road, Jiangsu Road and Anhui Road are all typical "planetary trees". These trees and historical buildings have witnessed the development and changes of Qingdao.

In order to protect these street trees with historical background, relevant departments have specially issued protection and management measures and established a database.

According to He Lei, deputy director of the Garden and Forestry Construction Division of the Qingdao Municipal Bureau of Landscape Architecture and Forestry, although some old street trees have not yet reached the standard of ancient trees, the landscaping department has also included them in the reserve resources of ancient and famous trees for meticulous management and protection. .

　　"The main urban area, especially the area around the ancient city wall, has many shops and limited land space. In the past, flowers and trees along the street were removed privately from time to time. Later, through publicity and guidance, everyone's awareness of protection was greatly improved, and this situation basically disappeared." Datong City Liu Kaiying, director of the Landscaping Research Center, said that recently it was discovered that an old locust tree that had been protected by a road was found to have limited growth. "We are planning to dig the surrounding road and expand the tree pool to allow the old locust tree to breathe better." '."

　　In the 1960s and 1970s, a large number of silver birches were planted in Kunming as street trees.

This tree is tall and luxuriant, but its branches are brittle and easily broken in rainy days, and are gradually replaced by other tree species.

Considering that decades of silver birch have left unforgettable memories for the citizens, Kunming especially left the whole road of old silver birch in Cuihu Ring Road, Qingnian Road and other places.

"Before the rainy season, we will check in advance and take preventive measures against branches with large curvature or inclination." Meng Ruidong said.

"It's worth our efforts to protect the street trees as much as possible, so that the memory of the city can be passed on from generation to generation with the street trees."

Make plans, make scientific arguments, consider the present and the long-term

　　"Almost every road widening and old street renovation project will cause tree damage. The very tall yellow juniper tree suddenly disappears," said Zhao Zhengrong, a reader in Chongqing.

　　With the development of economy and society, great progress has been made in the selection of tree species, engineering construction, and tree maintenance in various places, but the problem of arbitrary tree cutting and destruction still exists in some places.

　　Tao Yulai, a reader from Hefei, Anhui Province, recounted such an incident: the local phoenix trees on the Yangtze River Road were planted in the 1950s, and the citizens have deep feelings for this.

Later, in the road widening and reconstruction project, the plane trees were cut down, and the public had great opinions.

Since then, when Wuhu Road was renovated, the relevant departments retained the plane trees that have been planted for more than 70 years, which have been praised and supported by the public.

"Comparing the two, people found that it would have been great if the phoenix trees between Dadongmen and Daximen of Changjiang Road had been preserved," Tao Yu said.

　　According to Wang Jun, Dean of the Landscape Branch of Kunming Planning and Design Institute, in the early 1990s, my country's large-scale urban construction was just starting, and insufficient attention was paid to urban memory, urban style or historical and cultural imprints, and the historical and cultural value of street trees was recognized. If it is not in place, a large number of street trees with memories and feelings of citizens have been cut down.

"In recent years, with the development of the times, people pay more and more attention to the historical and cultural value of the city, and the understanding and protection of street trees are more in place." Wang Jun said.

　　"Qingdao always seeks the opinions of the landscaping department during road construction and construction, and listens to the opinions of the citizens extensively, so as to avoid the indiscriminate felling of street trees." During the construction of Metro Line 4, it applied for the relocation of nearly 100 large-scale plane trees on the surrounding roads. The Bureau of Landscape Architecture and Forestry communicated and coordinated with the subway construction unit and design unit for many times, and took measures such as adjusting the location of the subway auxiliary facilities and optimizing the construction plan to avoid the problem of Migration of some street trees.

"Recently, we are also working hard to coordinate the construction of Metro Line 9. The migration of more than 200 street trees has been reduced in Chengyang District alone." Wang Kechun said.

　　Liu Keyuan, a reader from Shaoguan City, Guangdong Province, pointed out that in urban construction, it is a common practice to remove street trees. "It seems that although it is not cut down directly, if it is moved around, the trees will die easily. Road construction must go through rigorous scientific research. Argumentation, the expansion of roads should also be considered in many ways. As the saying goes, 'the predecessors plant the trees, the later generations enjoy the shade', and protecting the current street trees is also a consideration for the future and for the benefit of future generations."
