How should we deal with the degradation of the Three North Shelterbelt?

I believe that many people are familiar with the "Three-North Shelterbelt", the Northeast region will be attacked by sandstorms a few decades ago, and the disappearance of sandstorms in recent years is closely related to the Three-North Shelterbelt. However, in some areas of the Three-North Shelterbelt, the shelterbelt is gradually disappearing. In particular, forest belts in rural areas are disappearing in large numbers.

What are the causes of shelterbelt degradation?

First, shelterbelts have been converted into cultivated land

In some rural areas, shelterbelts have been diverted to cultivated land, and people have simply forgotten the misfortune caused by sandstorms, mistakenly believing that there are more shelterbelts and less shelterbelts. In this way, shelterbelts are gradually reduced.

This is also the biggest reason for the disappearance of shelterbelts. In the face of this reason, the local area of the Three-North Shelterbelt should take some effective measures, such as increasing the publicity of the role of shelterbelts, preventing farmers from misappropriating shelterbelts, and if necessary, establishing a series of laws to control the people who misappropriated shelterbelts.

Second, the threat of rodent pests and insect pests to shelterbelts

In some remote areas, shelterbelts are not managed properly, resulting in some shelterbelts being harmed by rats and pests, resulting in the gradual disappearance of shelterbelts in the area.

In the face of the loss of shelterbelts due to rodent and insect infestations, the local area should take measures such as insecticide and rodent extermination, so that the shelterbelts in the local area can thrive, so that the three-north shelterbelts can be restored.

Third, the geographical conditions are poor, and the selection of trees is improper

The Three-North Shelterbelt is located on the edge of the desert and next door, and its geographical conditions are poor, which is not suitable for the growth of the main trees planted in the Three-North Shelterbelt. So much so that shelterbelts can easily disappear.

According to the local geographical conditions, analyze which plants are suitable for planting.

Fourth, the groundwater level is declining

In some areas, groundwater is extracted in large quantities in order to plant trees blindly, which has led to a drop in groundwater levels, which has led to the disappearance of shelterbelts. In view of this situation, the local area should arrange planting reasonably.

Fifth, improper management

For a long time, there has been a lack of management of shelterbelts, especially in some remote areas, where what should be planted is not planted, what should be tended is not tended, and what should be pruned is not pruned, resulting in improper management of shelterbelts.

In view of this situation, it is necessary to increase human and financial resources to manage the existing three-north shelterbelts and repair the degraded forests in a timely manner.

First of all, it is necessary to plant trees, but also to protect the environment, and not to litter, must do a good job of garbage classification, and the state should also strengthen the importance of management.

Our generation should protect the ecological environment more and plant more trees. Don't cut down anymore. The state should also make some incentives for this.

Much more. In accordance with the master plan,The construction scope of the Three-North Project is 4,480 kilometers long from east to west and 560-1,460 kilometers wide from north to south along Tianjin, Fenhe, Wei River, lower reaches of Tao River, Burhan Buda Mountain and Karakoram Mountain in the south.

Its geographical location is between 73°29 129°50 east longitude and 33°30 50°14 north latitude. It includes 559 counties (banners, cities and districts) in 13 provinces (autonomous regions and municipalities directly under the central government) of Shaanxi, Gansu, Ningxia, Qinghai, Xinjiang, Shanxi, Hebei, Beijing, Tianjin, Inner Mongolia, Liaoning, Jilin and Heilongjiang. The total area of project construction is 10,000 square kilometers, accounting for the total land area of the country.

The Three-North Shelterbelt is a forest belt planted in three provinces (Inner Mongolia, Gansu and Ningxia) in northern China in the 70s of the 20th century to prevent desertification. In recent years, there have been reports of varying degrees of deforestation in the Three-North Shelterbelt, resulting in shortages.

In fact, the area of the Three-North Shelterbelt and the status of the first cover have always been a concern of the state and society. According to data released by the National Forestry and Grassland Administration, by 2021, the Three-North Shelterbelt has developed into a huge ecological project with a total area of 10,000 hectares and a vegetation coverage rate of more than 30%. Among them, the forest cover area is 1.6 million hectares, and the grassland cover area is 10,000 hectares, and the development rate of desertification and desertification area has been effectively controlled.

Although the area and vegetation status of the Three-North Shelterbelt have improved, the original ecological and environmental problems have not been completely corrected, and stricter protection measures need to be taken to avoid any damage to the ecological environment. In addition, it is also necessary for all sectors of society to strengthen publicity, popularize the awareness of environmental protection, and work together to maintain and protect this huge ecological barrier.

The direct effect of the Three-North Shelterbelt on the prevention and control of sand and dust storms is mainly to weaken the driving force. Although the strong winds formed by atmospheric circulation cannot be eliminated by manpower, the surface wind speed can be weakened by strengthening the construction of forest and grass vegetation, so as to reduce the effect of sandstorms. This is a direct function of the Three-North Project.

The most fundamental thing is to protect and develop the productive forces of agriculture and animal husbandry through the construction of forestry ecology, reduce the management pressure on sandy land, and in turn promote the restoration and development of vegetation, so as to achieve the dual effect of weakening the power source and material source.

2] Three-North Shelterbelt: Three-North Shelterbelt Project [refers to the large-scale artificial forestry ecological project constructed in the Three-North region of China (Northwest, North China and Northeast China). In order to improve the ecological environment, China decided to list this project as an important project of national economic construction in 1978.

The construction of the three-north shelterbelt system in Northwest China, North China and West Northeast China has led to the rapid growth of forest resources and the increasing output of timber and forest products, changing the situation of lack of forests and trees in the past. The development of forestry not only improves the ecological environment, but also promotes the development of the rural economy, the three north region will be resource advantages into economic advantages, has developed 56.7 million acres of economic forests, the construction of a number of famous, special, excellent, new fruit base in the construction of the three north shelter forest system for more than 20 years of practice has accumulated rich experience, out of a Chinese characteristics of forestry ecological construction road.

The construction project of the Three-North Shelterbelt System is a grand project that benefits the present generation and contributes to the future generations, which is not only a major project in China's ecological environment construction, but also an important part of the global ecological environment construction. Its construction scale, speed and efficiency are more than the "Roosevelt Prairie Forestry Project" of the United States, the "Stalin Plan to Improve Nature" of the former Soviet Union and the "Green Dam Project" of the five North African countries, and are known as "China's Green Great Wall" and "the world's best ecological project" in the world. In recent years, experts, scholars and journalists from more than 50 countries have come to China to inspect the Three-North Shelterbelt System Project, and they have given high praise.

Northwest, North China, and Northeast China. Protect soil and water.

The Three-North Shelter Forest Kaizi is a large-scale ecological project that was implemented by China's first in the 70s of the last century, aiming to resist the spread of desertification and protect the ecological environment in the north. However, there are some reasons for its failure. First, the plan lacks science and sustainability.

In the early days of the implementation of the stalking, a large number of coniferous species were introduced, but these species were not adapted to the local environment, resulting in difficulty in growth and the death of a large number of trees. In addition, shelterbelts lack a comprehensive understanding of ecosystems and fail to take into account local vegetation, hydrology and soil characteristics, resulting in damage to the ecological balance. Second, management and supervision are inadequate.

The shelterbelt area is vast and difficult to manage, and the monitoring of vegetation growth and man-made damage is not timely and effective. Managers lack professional knowledge and experience to effectively solve ecological and environmental problems. At the same time, under the pressure of economic development, some places use shelterbelts for commercial development, destroying the original purpose of shelterbelts.

Third, there is insufficient social participation. The construction of shelterbelts should be widely involved in the construction of shelterbelts, but in the process of implementation, public participation is low, and there is a lack of effective publicity and education, resulting in insufficient environmental awareness, man-made destruction and illegal logging are difficult to control.
