Garbage becomes decoration, falling leaves not sweeping test city management
Our reporter Ma Aiping
In the early winter, trees all over the country started to fall leaves.
According to the Voice of China's "News Evening Peak" report by the China Central Radio and Television Station, the fallen leaves on the road in the past would soon be swept away.
However, in recent years, many places have introduced a policy of "leaves not swept" to provide the public with time and space to watch fallen leaves.
Turn on the "leaves without sweeping" mode in many places
On November 10, Shanghai announced a list of urban deciduous landscape roads in 2020, and 13 districts and 41 roads will successively start the "leaves without sweeping" mode.
In addition to Shanghai, in Beijing, Xi'an, Changchun, and Qingdao, there are also practices of "no leaves sweeping away" to let the beautiful scenery stay.
What is the reason for these cities to make the decision of "fallen leaves not sweeping"?
From the words of Chen Bo, deputy director of the Shanghai City Appearance and Environmental Quality Monitoring Center, we can see something.
He pointed out that the implementation of "fallen leaves without sweeping" will not destroy the natural scenery formed by fallen leaves. The roads are covered with various "carpets", making them a splendid background for street photography, highlighting the vitality and temperature of the city; the public can experience higher The quality of the fallen leaves scenery achieves the harmonious coexistence between man and nature. This is the best comment for the construction of a humane city; it fully demonstrates the concept of the people’s supremacy and the people’s city, so that everyone can participate in urban governance in an orderly manner. To enjoy a quality life, everyone can truly feel the temperature of the city.
"No sweep" is much harder than "must sweep"
"Actually,'falling leaves do not sweep' is not not sweeping, but slowly sweeping. The so-called'falling leaves do not sweep' means that after the leaves fall, when it has ornamental value, it will not be treated as garbage immediately, but will be let Fallen leaves become part of the landscape. After a period of time, after it has all dried up and its ornamental value fades, it will be cleaned.” Yao Shicai, deputy chief engineer of the Beijing Academy of Landscape Science and Technology, said in an interview with a reporter from the Science and Technology Daily.
Don't think that sanitation workers will get temporary relief without immediately cleaning the fallen leaves. In fact, on the contrary, their labor intensity has increased.
Yao Shicai said that the implementation of "fallen leaves without sweeping" requires sanitation workers to pick up the dead branches and other rubbish that accompany the fallen leaves and keep the good leaves.
And there are some areas, such as Beijing, where the climate is relatively dry, and the fallen leaves will dry out in a short period of time. Therefore, the fallen leaves are basically maintained for about a week or 10 days, and they need to be swept.
"If you need to keep the fallen leaves for a longer time, you need to spray water. But spraying water does not save labor or effort, so there are fewer ways to delay the drying of the fallen leaves by spraying water. In most areas, it is after the fallen leaves have dried out. When the wind blows up, clean them up in time." Yao Shicai said.
"Because the Yangtze River Basin has more precipitation and high humidity, it takes a relatively long time for the leaves to become dry after they fall. Therefore, the model of'falling leaves without sweeping' emerged earlier in the Yangtze River. "Sweep', it will be a little later in time." Yao Shicai pointed out that there are also regional choices for "fallen leaves without sweeping."
"In Beijing, most of the areas where leaves are not swept away are concentrated in parks or large green plots. When the road is actually on the road, it needs to be cleaned in time, because there is a lot of traffic and people on the road, and the fallen leaves are crushed by cars and people. , It's easy to get dirty, and it's not very ornamental." He said.
Is a more refined management model
Fallen leaves have changed from garbage to urban decoration. What is the change behind this?
Xi Yanli, a professor of the Department of Urban Planning and Planning of Renmin University of China, told the media that the current stage of urban development in China has actually been a stage of comprehensive improvement of management levels, management concepts and management methods.
In the past, safety was the primary consideration for urban management, so the most important purpose of cleaning all fallen leaves was to prevent fires.
Now on the basis of safety, there are new ideas and methods, namely the construction and management of people-centered cities, so beauty has become a very important theme of Chinese cities.
Yao Shicai pointed out that "fallen leaves do not sweep" is a positive management model in urban green space management.
The higher the degree of urbanization, the more refined the management will be.
In order to prevent falling leaves from causing fires, various localities have adopted many methods. For example, stricter regulations are adopted to not allow open flames to enter places with fallen leaves; or in important areas, spray water to maintain the humidity of fallen leaves.
In addition, fallen leaves are not only a decoration.
"It falls on the grass or under the roots of trees. After it gradually decomposes, it will become a kind of fertilizer." Yao Shicai said. There are also many green garbage treatment stations that can crush the fallen leaves and turn them into fertilizers. Return to the green space.
