[Abstract] Closing is to improve the ecological environment, restoring forest vegetation, expanding forest resources and improve forest cover most effective measures, with less investment and quick advantages. In the analysis of the Closing of the ecological environment in ecologically fragile areas of the status and role in the fixed side, closing off the action on the basis of proposed measures on Closing Dingbian implement the recommendations.

[Key words] Closure; Under the influence of natural disasters, we use the natural regeneration capacity of forests to implement regular mountain closures in mountainous areas with suitable natural conditions. We prohibit man-made destructive activities such as reclamation, grazing, and firewood cutting, and artificially promote natural regeneration and natural succession of plant communities to restore forest vegetation. It is a kind of afforestation method, which is a measure to naturally restore sparse forests, shrub forests, scattered trees, and barren hills suitable for forestation into forests. Through the implementation of the mountain closure and afforestation project, the forest vegetation has been rapidly restored, the species structure has become more reasonable, and the forest reserve resources are abundant, which facilitates the formation of an ideal forest community and enhances the ecological protection function of the forest. Mountain closure for afforestation is a policy measure that has low cost, fast greening speed, early utilization period, quick results, is conducive to protecting species resources, and can reduce forest diseases and insect pests. It plays a huge role in protecting the environment, protecting species resources, and achieving ecological balance.

1. The role of mountain closure for afforestation in the ecological environment construction of Dingbian County

Practice has proved that in the ecological environment construction of Dingbian County, mountain closure for afforestation is an important factor in improving the ecological environment, restoring forest vegetation, and expanding the ecological environment of Dingbian County. Forest resources are the most effective measure to increase forest coverage. It has the advantages of low investment and quick results. It is one of the measures to restore forest resources that is suitable for local natural conditions.

1. Closing mountains for afforestation is the best choice to restore forest vegetation and expand forest resources

Dingbian is located in the northwest of Shaanxi Province and the westernmost end of Yulin City, between the Loess Plateau and the Ordos Desert in Inner Mongolia. The grassland transition zone has a temperate semi-arid continental monsoon climate, with an altitude between 1303 and 1907m.

In the southern mountainous areas, the mountains are steep, transportation is inconvenient, labor is scarce, and forest management funds are insufficient, making it difficult to expand forest resources through artificial afforestation. Sparse forest land, unforested afforestation land, barren hills and wasteland suitable for forestation, and some shrub land were severely damaged. Therefore, through the implementation of mountain closure and afforestation measures, the vegetation of barren hills and wasteland and damaged shrubland can be restored and the area of ??forest resources in the county can be increased.

2. Closing mountains for afforestation is an effective way to restore forest vegetation and expand forest resources

In the southern mountainous area of ??Dingbian, animal husbandry is the main source of economic income for local farmers. The living conditions of local people play a very important role in promoting the development of local economy. However, the long-term overgrazing by local farmers in the forest area is the main reason for the destruction of understory vegetation in the southern mountainous areas of Dingbian, the degradation of pastures and the continuous rise of forest lines. In order to restore the forest vegetation in natural forest areas and prevent the rise of the forest line, measures can be taken to close the mountains for afforestation, ban or reduce the interference of human activities, such as mining, grazing, etc., and give the forests time to recuperate and allow them to reproduce or regenerate naturally. Under the premise of natural restoration to forest.

3. Mountain closure and afforestation requires less investment, quick results, and saves labor and time

Generally, 1hm2 of forest closure can be used for 43 to 75 man-hours, while artificial afforestation requires 300 to 750 man-hours. per hectare, plus the cost of seedlings, the cost of afforestation per hectare is several to dozens of times higher than that of mountain closure for afforestation. Moreover, the mixed forest formed by closing the mountains for afforestation can produce various forest by-products, which is conducive to the development of various businesses and increases the income of the people. In a mountainous area in southern Dingbian, a place where afforestation is difficult, investment is insufficient, and people live in relative poverty, the use of mountain closures for afforestation is undoubtedly the best choice to restore forest vegetation.

2. The role of mountain closure for afforestation

1. Expand the forest area, promote natural regeneration, and improve the forest quality

The encroachment of forest land and the destruction of shrubs are the key to determining the edge. The conflict between forest and livestock is most prominent in the Beitan natural forest area. About 30% of shrub land and sparse woodland have been turned into pastures, and are seriously overloaded. Therefore, mountain closure for afforestation is an important measure to protect shrubs and sparse woodland, and is a key measure to expand the area of ??natural forest areas and improve the quality of forest land.

2. Reduce man-made destruction and promote natural regeneration

Implementing mountain closure and afforestation measures can effectively reduce man-made theft, theft, and felling of forest trees and protect forest resources; it can also reduce the damage to the surface caused by human activities. The instability in the soil promotes natural planting and seedling germination and growth; it can effectively protect the seedlings and saplings in the enclosed area from human destruction and livestock gnawing and trampling, and promote the saplings to become forests.

3. Closing mountains for afforestation can form mixed forests

Forests cultivated through closures are mostly mixed compound-layer stands that combine trees, shrubs, and grasses. They have a large amount of dead branches and leaves, which can Improving site conditions, forming a good forest environment, laying a good foundation for the growth and development of the forest, maintaining soil and water, conserving water sources, improving the climate environment, improving forest quality, expanding forest resources, enhancing the forest's resistance to diseases and pests, and promoting diversified operations It plays a multi-faceted role in developing and increasing the economic income of the masses.

4. Give full play to the various ecological benefits of forests more effectively

A stable forest ecosystem can effectively regulate the dynamic balance of material and energy flows, so that its ecological benefits can be achieved Effectively used, mountain closure for afforestation reduces the damage caused by human activities, makes the fragile forest ecosystem in Dingbian County more stable, and makes the flow of materials and energy more reasonable, so that the ecological benefits can be fully exerted.

5. Improve the level of management and protection and promote forest canopy closure

Adopt artificial auxiliary measures in the closed area to improve the forest environment; different intensities can be used according to differences in the local ecological environment. , intervene in different ways to promote the progress and succession of vegetation; can effectively increase the accumulation of nutrients in the forest and promote the activities of soil microorganisms; can gradually master and apply vegetation succession laws and dynamic changes in a series of management and protection activities, and continuously improve Management level.

6. Improve the stability of the forest ecosystem and protect biodiversity

After the closure, human activities in the forest decreased and the diversity of biological species increased, making the fragile ecosystem gradually Zhejiang is recovering, developing in a stable direction, and its ability to resist natural disasters and human interference has been enhanced, which can effectively protect biodiversity.

3. Suggestions on closing mountains for afforestation in Dingbian County

1. Strengthen policy guidance, protect and utilize simultaneously

The ecological environment construction in Dingbian County is a complex task The system engineering is related to the sustainable development of society, economy and environment in the entire Yulin region. Active policy guidance can promote the construction and development of the ecological environment in ecologically fragile areas. The policy of returning farmland to forest has benefited farmers throughout the county, while the mountain closure and grazing prohibition have restricted the development of animal husbandry, directly affecting the economic income of farmers. Therefore, flexible and realistic policies must be adopted to promote the construction and development of the ecological environment in Dingbian.

2. Improve the quality of forestry employees and increase the scientific and technological content

Science and technology are the primary productive forces, and high scientific and cultural quality of employees is the key to developing forestry production. Cultivating a high-quality forestry workforce and actively promoting new methods and technologies in this profession are urgent tasks for the current development of forestry. Promoting forests through science and technology plays a positive role in improving the quality of forestry workers, cultivating forestry science and technology teams, increasing scientific and technological content, and promoting the development of forestry. In the future, we must strengthen the improvement of the overall quality of employees and further accelerate the pace of forestry science and technology development.

3. Flexibly use dynamic management theory in mountain closure and afforestation to promote the restoration and reconstruction of vegetation

Dynamic management means using different methods at different stages of succession based on the phased rules of vegetation succession. The theory of vegetation restoration and reconstruction is to carry out afforestation of tree species and protect tree species that help promote succession to shorten the succession cycle. This idea has positive guiding significance for promoting vegetation construction in Dingbian natural forest areas.

4. Scientific planning, classified guidance, and classified management

A scientific plan for mountain closure and afforestation must be made, based on the characteristics of different ecosystems in the Dingbian natural forest area and the formation and succession of vegetation. According to the laws and stages, dynamic management ideas should be flexibly applied to carry out classified management, gradually build a vegetation system suitable for the ecological environment and economic development level of mountainous areas, and promote the construction of ecological environment in mountainous areas. ;
