The significance of desertification control, the harm of desertification

1.It is conducive to the development of the industrial structure according to local conditions.

The all-round development of agriculture, forestry, animal husbandry, and sideline fisheries can increase peasants' incomes, promote local economic development, improve peasants' living conditions, and enhance their quality of life.

2.It is conducive to protecting land resources and improving the local ecological environment.

3.It is conducive to promoting sustainable ecological and economic development.

Desertification.

Typical regions of China: Northwest China (Xinjiang, Qinghai, Inner Mongolia and other places) Causes: (1) Natural causes:

global warming, evaporation is vigorous; It is located in an inland area with little precipitation; Mice; Locust infestation. (2) Human causes: overgrazing; excessive woodpicking; over-reclamation; irrational use of water resources; Improper protection of the construction of transportation lines and other projects.

Governance measures: formulate laws and regulations on grassland protection and strengthen management; control of livestock carrying capacity; the construction of the "Three-North Shelterbelt"; returning farmland to forests and pastures; construction of artificial grasslands; promotion of rotational grazing; It is forbidden to harvest fat cabbage, etc.

Governance significance: It is conducive to the adjustment of the industrial structure according to local conditions, so that agriculture, forestry, animal husbandry and sideline fishery can develop in an all-round way, which can increase farmers' income, promote local economic development, improve farmers' living conditions and improve their quality of life; It is conducive to protecting land resources and improving the local ecological environment. It is conducive to promoting sustainable ecological and economic development.

The hazards of desertification are: the decline of the production potential of the land, and the gradual decline and disappearance of the biological production potential of the land due to desertification; declining land productivity; The quality of pasture has declined, and the development of animal husbandry has been hindered for a long time due to the harm of land desertification, and many areas have shown a downward trend.

Desertification is a natural (unnatural) phenomenon caused by the decline or loss of productivity of large areas of soil due to drought and lack of rainfall, destruction of vegetation, overgrazing, wind erosion, erosion of flowing water, soil salinization, etc. The term "desertification" began to spread. The end result of desertification is mostly desertification.

Desertification control requires extensive international cooperation and the participation of all countries in the world.

Desertification and poverty exacerbate each other, creating a vicious circle. Poverty leads to more irrational use and exploitation of land and natural resources in the short term. At the same time, desertification threatens food production, affects biodiversity, affects political stability, leads to migration, etc., and triggers and exacerbates poverty.

Desertification control measures are as follows:

1. Further intensify publicity and education to improve people's awareness of ecological and environmental protection.

2. Establish and improve the monitoring system of soil desertification, conscientiously do a good job in the dynamic monitoring of sandstorms, comprehensively understand the current situation of soil desertification, and put forward a scientific basis for the prevention and control of sandstorms.

3. Establish a sound legal system, formulate and improve relevant laws and regulations, and strengthen the control of desertification in accordance with the law. We will intensify law enforcement, implement measures to ban land reclamation, grazing, and woodlogging, and resolutely crack down on all kinds of environmental violations that destroy vegetation, such as deforestation, land reclamation, and grassland reclamation.

4. Conscientiously implement the "National Plan for Desertification Prevention and Control", formulate effective implementation plans, scientifically use the existing grasslands, have planned grass collection, scientific rotational grazing, grazing, and strengthen the management of grassland rodents; It is necessary to return farmland with low yield to grassland tolerance in the surrounding areas of the grassland area, which is seriously lacking, and ban grazing on the grassland with extremely serious desertification.

5. Further invest in capital and technology to speed up the vegetation restoration of existing desertified land through measures such as planting trees and grasses, and actively encourage enterprises and individuals to invest, and combine it with the development of characteristic economy to achieve a win-win situation for the ecological environment and economy.

6. Popularize and apply practical technologies and models for desertification prevention and control, strengthen technical training and demonstration work, and make desertification prevention scientific.

7. Do a good job in the key work of desertification prevention and control, build a comprehensive demonstration area for desertification prevention and control, and build a new pattern of desertification prevention and control development with points and areas.

8. Reduce the population capacity of the environment, reduce the population pressure, implement the necessary immigration policy, and gradually move people who exceed the environmental capacity out and transfer to small towns in places with poor living conditions.

1. Natural causes:

1. Climatic characteristics of arid limb disturbance. (Mainly from the geographical history, location, topography, climate and other aspects of consideration).

2. Abnormal climate.

2. Human reasons:

1. The population boom has increased the pressure on the environment.

2. Improper human activities, excessive and unreasonable use of land resources and water resources.

excessive woodpicking; Overgrazing.

over-reclamation; Improper use of water resources.

No attention is paid to environmental protection in the construction of industrial and mining transportation.
