What are the larger urban greening and maintenance projects in the country, and what are their chara

General greening refers to the planting and maintenance of plants, while gardening is the highest form of expression composed of various elements including greening. At present, with the rise of the concept of property management city, more and more urban road greening management services have been integrated into the integration of sanitation, and enterprises in the sanitation service industry are responsible for maintenance.

Among them, the more famous is the PPP project of environmental sanitation integration in Xin'an, Fuyong and Fuhai streets, Bao'an District, Shenzhen, which is currently undertaken by Infore Environment. Among them, only 2.6 million square meters of green management area were reported, and nearly 60,000 street trees needed to be maintained.

The characteristics of greening management and maintenance in Guangzhou and Shenzhen are as follows:

1. The municipal greening level is divided into four levels according to its geographical location, fine management requirements and maintenance difficulty: special green space, first-class green space, second-class green space and other green space.

2. The maintenance operation includes: green space maintenance, shrub maintenance, flower belt maintenance, arbor maintenance, replanting and renewal, and soil improvement.

3. Due to the particularity of the maintenance operation, there are corresponding requirements for road occupation operation, and it is necessary to set up safety belts for road occupation operation.

4. The working tools and pharmacopoeias of maintenance operations (pest and disease agents, wound protection agents and common agents) are subject to the corresponding operation safety requirements rules.

5 Different from general sanitation services, greening management requires the establishment of a special department with a special organizational structure, including high-altitude pruning, daily maintenance, sprinkler irrigation and digital processing departments. Among them, daily, regular and special inspection teams are set up for daily maintenance needs to inspect the corresponding greening facilities and plants in different dimensions.

6. Emergency measures should be taken, including extreme weather, pests and diseases, flood prevention, fire prevention and traffic accidents.

In May 2020, Infore Environment won the bid for the PPP project of sanitation integration in Xin'an, Fuyong and Fuhai streets in Bao'an District, Shenzhen, as the largest sanitation project with the total contract amount in the history of sanitation, the project includes cleaning, transportation, greening, garbage classification and other sectors. Among them, the green sector: the maintenance area is close to 2.6 million square meters, and there are more than 60,000 street trees.

It covers various greening operation scenarios such as municipal road greening, community greening, and seasonal flower sketches.

Main features: 1. Complete equipment - aerial work vehicles, forklifts, intelligent greening operation vehicles, new energy water trucks and dump trucks and other vehicles and various types of chain saws, lawn trimmers, and other small equipment are readily available, equipped with a modern greening maintenance team.

2. High standards - from the owner's assessment requirements to the company's internal management, a series of standard requirements for each maintenance scene have been formulated.

3. Personnel - hundreds of operators, perfect personnel organizational structure, up to the project manager, project supervisors of various sectors, down to all kinds of maintenance workers, pruners, aerial workers, each performing their duties, so that watering, pruning, spraying, replanting the greening maintenance work in an orderly manner.

The urban greening maintenance project has the same characteristics as the sanitation project, that is, it is labor-intensive, but unlike the sanitation project, the working hours of the greening personnel are more flexible, therefore, if the employees of the two businesses are used by the company as a whole, a single greening company and a single sanitation company can not compete in the cost, and the combination of sanitation + greening maintenance has the economic basis for raising the salary of front-line employees, which can stabilize the market and increase profits for the company. At the same time, sanitation + greening can be reasonably configured and used in vehicles, because the sprinkler trucks, road maintenance vehicles and garbage trucks used in sanitation vehicles can be used as greening vehicles, which can enable the project company to save costs and reduce investment.

Shenzhen Bao'an Fuhai, Xin'an greening and maintenance project. Shenzhen is a national garden city, a national forest city, China's first international garden city city, in 2000 won the first place in the international garden city evaluation E city, the international garden city is recognized as the global urban environment green Oscar. Shenzhen ranked first in the "2018 Comprehensive Assessment of China's Urban Construction Level", and its greening score also ranked first.

The green coverage rate of Shenzhen's built-up areas is 921, the per capita park land is square meters, and the city has built 2,400 kilometers of greenways. In 2020, there will be more than 1,000 in Shenzhen, with a green coverage rate of more than 50%.

The construction process, functional requirements and business objectives of urban greening are different from those of forestry. But all are part of production and construction, one.

It is mainly based on materials, and the other is based on environmental protection. Urban greening is an investment in social and environmental capital, and its economic returns are multifaceted, and.

It's very rich. The city's demand for gardens is divided into two aspects: one is as infrastructure; The second is as a leisure facility. The former should be shared by the municipality as a public good to all citizens, while the latter can be provided to some citizens by legal entities as a legal product.

On the basis of traditional Chinese gardens and modern gardens, the garden city is closely integrated with urban development, adapting to the needs of the city and conforming to the contemporary people.

The need to take the entire urban area as the carrier, to realize the entire urban area of the landscaping and the construction of a new type of garden city for the purpose of the purpose of the garden.

Forest. Its overall goal is "clean air, beautiful environment, and good ecology." Harmony of human settlements. One of its outstanding features is that there are towns in the city, towns in the suburbs, forests in the towns, and towns in the forests.

Shenzhen's greening maintenance is very good, the deepest feeling is that although Shenzhen is developing rapidly, but century-old trees can be seen everywhere, which is enough to prove that the local ** and residents attach importance to greening and maintenance, and care about the living environment, in many urban villages in Shenzhen, you can see a large banyan tree of hundreds of years, as well as parks, there will be aunts and uncles under the trees, with children, under the trees to enjoy the shade, chat, feel very good.

Large-scale urban greening and conservation projects are generally distributed in coastal areas, and the development of the area itself is at a high level, and the standard requirements for greening and maintenance are relatively high. Shenzhen Bao'an will have a relatively large-scale urban greening maintenance project in 2020.

Large-scale urban greening and maintenance projects are mainly in coastal areas, such as Shenzhen and Xiamen.

The greening project in Bao'an District, Shenzhen, is currently the largest environmental sanitation integration project in China.

It should be concentrated in the first-tier cities.

It is understood that the three streets of Bao'an, Shenzhen are famous urban greening maintenance projects, which have the characteristics of high professional requirements, showing the spiritual outlook of the city, protecting ancient flowers and trees, and adapting measures to local conditions.

The vast majority of economic development is more prosperous in the place of greening can be done, as far as I have been, our country's greening is better in Shenzhen, Hangzhou, Nanning, Nanjing, Kunming, Suzhou and other cities, after all, to make money to start to emphasize the harmonious development of man and nature, but in fact, then again, I personally think that the main difficulty in improving the local greening rate is the development of the economy, especially in recent years, the pressure of the economic downturn is very great, and the financial expenditure is becoming more and more self-conscious. If we can still come up with some funds to use the ecological environment in the period of rapid economic development, then under the current economic situation, everyone is tightening their belts to get by, and it can only become more and more difficult to get money out of the reduced financial plate to carry out greening. After all, if we want to develop, GDP is often in the first place, and the ecological environment often cannot create direct benefits, which is also a contradiction in development.

In addition, the shortage of urban land is also an important factor restricting the increase of local greening rate. As a result, the land that can be given for greening is very limited, especially in some places where every inch of land is valuable, and it takes a huge cost to renovate, but it is unlikely to change this situation in a short time. It can only be said that the improvement of urban greening rate in the future can only become more and more difficult.

However, in the long run, the construction of ecological civilization should still be placed at the strategic height of urban development, Jinshan Yinshan or lucid waters and green mountains, only children make choices, adults must be, but in this process, we should respect the laws of nature, can not do it blindly, to scientific greening, according to local conditions, so as to achieve the harmonious development of man and nature.

The level of urban greening rate is a more subjective thing, statistically because the meaning of the so-called greening rate is relatively vague, the statistical data of each family is not the same, the following rankings can be used as a reference, but in general, the greening of large cities is not bad.

As for the difficulties, I think the biggest factor restricting urban greening is the economy. Through the above rankings, we can see that in addition to the environment itself, the city where plants grow is the city with a high level of economic development, and the greening rate is high, mainly due to the following reasons:

1. A change in concept. Only when we have enough to eat can we pursue spiritual civilization and health.

2. The general improvement of cultural level. Economic development is accompanied by the development of education, the people's cultural level continues to improve, and they gradually realize the importance of green, so that the development of relevant theories and the generation of relevant talents.

3. To improve the greening rate, reasonable land planning, scientific garden design and mature logistics and infrastructure support are required, which require the city to have a certain economic foundation, which can attract enterprises and talents in related industries to settle in, and can provide sufficient financial support to relevant departments.

Laxatives, generally speaking, economically developed cities, the greening rate will be generally higher, the greening rate of coastal cities is higher than that of inland cities, the greening rate of southern cities is higher than that of northern cities, mainly located in the forefront of Shenzhen, Hangzhou, Nanning, Nanjing, Kunming and other cities, of course, with our country in recent years, Jinshan Yinshan, is the strategic layout of lucid waters and lush mountains, more and more cities have begun to join the green action.

The climate is of course partially affected by the above-mentioned status quo of green coverage, and the original green coverage rate of the city also has a certain impact. However, I think that these are not the decisive factors, one of the biggest constraints, is the level of regional economic development, we only have money first, will pay more attention to their surrounding environment, if even the food is not enough, there is no way to protect the environment, improve the rate of urban greening has the following major difficulties:

1.Economic development, urban land is expensive, land is tight, it is not easy to plan a special green land, after all, it is difficult to see economic benefits in a short period of time.

2.The unreasonable planning is, on the one hand, to adapt measures to local conditions, and on the other hand, scientific design, mature logistics support, and abundant special funds are indispensable.

3.Awareness is limited, and the protection of the environment has not yet risen to the strategic level of urban development, and the relevant resource support can be further enhanced.

Of course, the decisive factor is to pay full attention to the establishment of special funds. In fact, a complete set of solutions for greening maintenance is also relatively mature. Only when our concepts and resources keep up, our living environment will be truly "green".

The top cities with the highest greening rate in China are Qinhuangdao, Jiaxing, Zhuhai, Beijing, Xiamen and Shenzhen. Of course, in recent years, many cities have begun to go green in the construction of China's lucid waters and lush mountains.

In terms of urban greening, there are professional and technical personnel to join in the urban planning and lay out the greening in advance.

The rational planning of road boulevards, park greening, and residential floor area ratio has played a guiding role for many industries. Shenzhen** has handed over the greening of some areas to professional enterprises to operate. Enterprises plant green plants and flowers in the park, and through professional artificial cultivation technology and careful care, they can appear in the life of the general public in the most beautiful manner in a very short period of time.

Shenzhen is just a pilot, like "Infore environment" such environmental leading enterprises, China has a lot of them, they stand at the forefront of "lucid waters and lush mountains are invaluable assets", and are committed to building a first-class ecological environment demonstration area in China, serving more people.

The greening rate of cities in southern China is generally high, mainly in the forefront of Shenzhen, Zhuhai, Guiyang and other cities; The greening rate of northern cities such as Qingdao and Weihai is relatively high.

There are several difficulties in improving the urban greening rate:

1. Land use problem, at present, every inch of urban land is expensive, and green land is relatively tight;

2. Vegetation necrosis, the survival rate of green plants in extreme climates is difficult to guarantee, and the replanting of green plants also requires a certain period;

3. Funding issues, the maintenance and replanting of green plants require higher costs, which is a greater test for the financial affordability of the local government.

Leshan, Dalian, Xiamen, Zhuhai, Hangzhou, Shenzhen, Yunnan and so on are all OK. The urban green coverage rate is the ratio of the total area of various types of urban green space (public green space, street green space, courtyard green space, special green space, etc.) to the total urban area. The level of urban green coverage is one of the important indicators to measure the quality of urban environment and the living welfare level of residents.

The biggest difficulties in improving the urban greening rate are as follows:

1.How to connect construction and management - how to solve the shortcomings of heavy construction and light management and protection has become the key to the exploration of the construction of forest cities in various places.

2.How to coordinate greening and industry - While emphasizing the visual effects of evergreen, colored leaves, and flower colors, the construction of Forest City should also pay attention to the combination with industrial development.

How to innovate the system and mechanism - At present, all localities are actively improving the rate of urban greening. However, due to the extreme shortage of urban afforestation land and the lack of capital investment, increasing the afforestation and greening area is inseparable from institutional innovation.
