What is the current status of land desertification and forestry development?

1.Natural resources have declined sharply

Relevant data surveys show that the plain greening work in many areas is still stagnant, and the first department has not effectively guided the plain greening work. Phenomena such as indiscriminate felling of trees, deforestation and land reclamation, and economic development at the cost of environmental damage still exist.

In the fifties and sixties of the 20th century, many areas have implemented mountain closure for afforestation, with the aim of creating a good living environment for future generations. The initiative has achieved good results at first, but with the development of the country's economy, the behavior of open and secret closure still exists, and some areas only close forests and green areas without cultivation, resulting in a sharp reduction in forestry resources across the country, and the ecological environment is not effectively protected.

The probability of occurrence of various geological disasters and natural disasters has increased, and floods, droughts, sandstorms, and mudslides have all had a serious impact on people's stable life and national development.

2.The conservation rate of afforestation is low

Although the state has introduced relevant policies in recent years to vigorously promote the development of environmental protection and carry out afforestation activities under the guidance of the first, it is restricted by economic conditions and natural conditions, and trees are planted every year, but no trees can be seen.

On the one hand, the survival rate of trees is low, and they are easily affected by factors such as pests and diseases, temperature, and geological environment. On the other hand, after the completion of the cultivation work, the maintenance of the trees is not done, the capital investment is insufficient, and there is a lack of talent team with strong professional ability and high comprehensive quality, which makes it difficult to carry out all the work smoothly.

3.The types of land use are complex

From the perspective of land conditions, the types of land use in many areas of China are diversified, which is one of the important factors causing the aggravation of land desertification.

In addition, there are large differences in land conditions in different regions, for example, the stability of land use in the north is relatively small, and many land use channels are constantly changing, except for fixed agricultural production land. In the context of increasing desertification, the efficiency of land use has been greatly reduced, which has caused a serious waste of resources.

4.Resources are unevenly distributed

Before the start of the treatment work, it is necessary to have a comprehensive understanding of the distribution of resources, carry out investigations, and understand the vegetation in desertified areas, so as to make reasonable adjustments to the treatment plan according to the actual situation.

In the process of controlling land desertification and desertification and carrying out forestry undertakings, it is necessary to adopt appropriate measures to concentrate on the establishment of reserve resources, vigorously develop animal husbandry, and better solve the problem of uneven distribution of resources.

The current situation of contemporary land desertification and forestry development is still very good, and the desertification of land is decreasing so far, but the development of forestry in the future is constantly increasing, and it is also constantly improving.

Now the development of forestry is very good, many deserts have been planted trees, has achieved greening, the development is very good, protect the environment.

The current situation is that the development of forestry in China is still relatively prominent, and now a lot of desert land has been turned into forestry. In the future, the development of forestry will definitely become more prominent.

The current situation of contemporary land desertification and forestry development is very good, because China attaches great importance to the development of forestry.

The development is very good, and there will definitely be a particularly good development in the future. It will also stand firm in society.

1.Desertification reduces the natural productivity of the land and affects agricultural development. In the process of wind erosion, first, the particulates in the topsoil are blown away, resulting in a coarse soil texture, a decrease in the water-holding capacity of the soil, and a decrease in vegetation cover, which is the main cause of desertification.

Most of the rainfall in this area is heavy rain and high intensity. In addition, the terrain is undulating, and rainwater is not easy to seep into. Although the rainfall per unit time is high, it rarely penetrates the soil, resulting in a lack of water in the soil after heavy rainfall.

2.Flooding is increasing, and frost, hail and flash floods are increasing in the region as desertification expands. There are many mountains, high terrain, susceptible to the influence of high air currents, early frost, hail, and flash floods are frequent.

Due to the short rainfall time and high intensity, the surface vegetation coverage area is small, and the protection of water resources is difficult. During heavy rains, it is very easy to produce runoff, form flash floods, wash away farmland, cut off transportation, damage water conservancy facilities, and bring huge losses to local agriculture every time floods and hail disasters.

3.The impact of grassland desertification on the development of animal husbandry is very significant. When desertification erodes the grassland, the dominant species of S. lanceolata decreases, the palatability herbs decrease, the weeds such as Artemisia frigida increase, and the amount of grass in the grassland decreases, which restricts the development of animal husbandry.

4."Desertification of land"It is a process of environmental degradation, in which excessive human activities destroy the fragile ecological balance of arid and aeolian sand surface environments, resulting in the emergence of desert landscapes characterized by aeolian sand activities in primitive non-desert areas, thereby reducing land productivity. Desertification is not only a global ecological and environmental problem, but also a prominent geological problem.

One serious problem is that "global desertification is still expanding".

5.Land productivity has fallen sharply. Soil erosion is an important part of desertification, and it is also the primary link of desertification. Wind erosion can cause the loss of organic matter and fine particulate matter in the soil, causing soil coarsening and fertility reduction.

6.Reduction of available land resources. Desertification means land degradation.

The continuous decline in land production capacity will lead to a reduction in the sale of land for agricultural and animal husbandry production, and farmers and herders will be forced to "eco-migrate". Desertification can also cause or make human habitation and production land suffer severe sandstorm disasters and resource shortages, resulting in the decline or even disappearance of land population.

So how to manage it? adjust the land use structure that is not conducive to the virtuous cycle of the ecological environment, and rationally arrange the proportion of agriculture, forestry and animal husbandry; Closure of abandoned farmland and degraded grassland and restoration of vegetation; Zonal rotation or crop rotation harvesting to limit the number of livestock carried; The sand fixation method is mainly based on plant sand fixation, supplemented by engineering measures.

Land desertification has a very high reputation on agriculture, affecting agricultural planting area, agricultural planting methods and methods, agricultural income, agricultural planting, and agricultural harvest.

It will reduce the natural productivity of the land, which will affect the development of agriculture, and desertification will become larger and larger, leading to soil erosion, which will also have an impact on animal husbandry, and agricultural production will be greatly reduced, and plants will not be able to grow.

The impact is very large, it has seriously affected the development of agriculture, affected the progress of agriculture, and brought a great blow to the agricultural industry.

It affects the yield of plants, affects the growth of plants, affects the surrounding environment, affects the land, and affects the place where people live.

Forestry should be developed on a large scale, and land desertification control measures such as artificial afforestation and grass planting, sand closure and grass cultivation, restoration of natural vegetation, setting up sand barriers and sand fixation, developing water conservancy, and soil improvement should be carried out.

We should plant more trees, plant more forests, pay attention to agricultural development, protect the ecological environment, avoid environmental damage, and reduce the felling of trees.

We need to find a way to turn these wastelands into oases, and we need to prepare a lot of trees, and a lot of people can plant plants on this wasteland, so that the environment can be improved.

<>1. Reduction of available land resources. Desertification means land degradation, and the continuous decline in the productive capacity of desertified land will lead to a reduction in land for agricultural and animal husbandry production, and farmers and herders will be forced to "ecological migration". At the same time, desertification will also affect the land for residential production by severe sandstorms and resource shortages, resulting in the reduction or even disappearance of land population.

2. Threatening traffic safety. Shifting sand dunes can bury roads and railways; Sandstorms can reduce atmospheric visibility and force airports and roads to shut down.

3. Natural disasters are intensifying. The most obvious aspect of desertification is the intensification of natural disasters. Sandstorms, sandstorms, and smog are natural disasters that ruthlessly disrupt the order of our production and life, and even endanger people's health.

4. Land productivity is in serious decline. Soil wind erosion is not only a major component of desertification, but also a primary part of hunger. Wind erosion causes the loss of organic matter and fine-grained matter in the soil, resulting in soil coarsening and reduced fertility.

5. While shaping the beauty, the sand movement caused by the overall movement of sand dunes, surface wind erosion, sand cutting, sand burial and sand dust release, etc., has caused serious harm to farmland, grassland, rotation of industrial and mining industries, major transportation facilities and natural and cultural heritage, and greatly exacerbated the occurrence of disastrous weather such as land desertification and sandstorms, and the average annual economic loss of China's sand disaster due to wind and sand disasters has exceeded 50 billion yuan.

6. Governance: Adjust the land use structure that is not conducive to the virtuous cycle of the ecological environment, and reasonably arrange the proportion of agriculture, forestry and animal husbandry; enclosure of desertified abandoned farmland and degraded grassland to restore vegetation; Adopt zonal rotation or rotation to limit the number of animals carried; The sand fixation method is mainly based on plant sand fixation, supplemented by engineering measures.

1.Human activity.

The pressure of population growth on land is the direct cause of land desertification. Overgrazing, extensive management, blind reclamation, irrational use of water resources, excessive deforestation, and irrational mining in arid land are the main manifestations of accelerated desertification expansion of human activities. Indiscriminate digging of Chinese medicinal materials and deforestation are human activities that directly lead to land desertification.

In addition, irrational irrigation methods have also caused secondary salinization of cultivated land.

2.Geographical and climatic factors.

Arid and semi-arid and sub-humid arid regions are located deep in the hinterland of the continent and are the most arid and fragile environmental zones with the least precipitation, the largest evaporation and the same latitude in the world. Desertification develops when the climate becomes drier, and when the climate becomes wetter, desertification reverses. In recent years, sandstorms that frequently occur in northwest China and north China (north) have aggravated the desertification process in these areas.
