What plants can better prevent desertification?

For example, the sand willow, Saxon tree, Populus euphratica, flower stick, etc., can play a good role in preventing desertification, these plants grow faster, require less water, and their root system is very strong to lock sand and water, which is very suitable for arid and desertified land.

It is definitely necessary to choose plants that use less water, not to plant trees as soon as they come up. And each desert has its own endemic plants, for example, chestnuts, in American westerns, cowboys often drink tequila when they go to bars, and agave is desert vegetation.

Start with low bushes or even turf. Some people say that it is good to use trees, but the principle of afforestation is: adapt to local conditions, and choose the right tree in the right place.

As the name suggests, you can only plant trees where they can grow. The edge of the desert may not have been a desert before, but the land could have been planted with trees. But it's hard to say when the area becomes a desert, with moisture and bad weather being the biggest limiting factors for tree survival.

Trees die within a few years of depleting groundwater, the water table drops, and the climate improvement of small groves should not keep up with the rate at which the environment becomes drier.

At present, the way we green the desert seems to be planting trees on the desert, because the trees need to draw a lot of water from the ground, so this behavior is equivalent to trying to drain the groundwater below the desert (probably bias, because there is no field investigation), and the results of such greening can be imagined. I haven't studied much about the greening policy, but I have thought about it technically: if you want to really green the desert, there is only one way that is feasible, and that is to raise the groundwater level of the desert to a point where plants can survive for a long time, and to keep it below the plant death line.

The prevailing view is that from the perspective of a non-graduate of desertification control, it is not to control the desert, but to prevent the further expansion of the desert and slow down the rate of desertification, so tree planting as a biological measure is effective and necessary. However, tree planting is not planted in the desert, or near the edge of the desert, to prevent the expansion of the desert shelter forest, generally built in the wasteland that is about to desertification, originally has a certain vegetation base, after the selection of suitable tree species can provide enough water and will not cause too much damage to the original ecology of the area planting trees, combined with engineering measures, management measures and a series of the best conditions that human beings can provide.

In fact, it is not entirely true, for some places where there is a shortage of water, the first thing to do to prevent desertification is to plant grass, because grass requires less water and will not further aggravate the local water shortage.

Generally, sand barriers (clay lattices, grass lattices, etc.) are used as the guide, supplemented by irrigation and planting desert vegetation, such as the Tazhong Highway and oil fields, and along the Lanxin Railway. The Tazhong Highway is a sand barrier and a drip irrigation desert vegetation with salty water pumped underground, which can basically only grow shrubs, not trees.

I won't list them all, the main thing is to form a weathered shell, or fix sand, but after a period of time, other plants will appear.

My home is in Alxa Right Banner, and it only takes ten minutes to the Badain Jaran Desert, and you can directly see the desert in the city. Growing up on the edge of the desert, I have been organizing various trees to plant trees on the edge of the desert since elementary school, but now I can't find the few trees I planted. In fact, the situation of deserts in various places is different, grass is grass, sand is sand, and forest is forest.

Don't drain the groundwater in the desert area because of production and life.

I think that planting trees in the desert can purify the air, beautify the environment, and help protect the ecological environment, if soil erosion and land desertification are effectively controlled.

It can improve the environment of the desert, but also improve the environment in which we live, and reduce the occurrence of sandstorms.

If you plant trees in the desert, it is especially good for the local environment, because trees can prevent soil erosion, and can also prevent dust and sand fixation, which has a great impact on human habitation.

Afforestation in the desert purifies the air, beautifies the environment, produces oxygen, prevents the movement of sand dunes and reduces wind and sand.

The first is to be able to prevent wind and fix sand, which is the most important point, the second is to change the environment of the place, and then to drive local income through afforestation.

It can help those creatures in the desert that we don't know about, and it can also block the wind and sand, especially the wind and sand, which is particularly effective.

Planting trees in the desert can have many benefits, such as increasing the likelihood of rain and oasis.

The reason why deserts form deserts is that it should be due to the geographical environment, rainfall is scarce, and human development is carried out! Decades of experience have shown that deserts cannot be planted with trees as humans want, and that they increase the water burden in desert areas, where deserts are only suitable for growing grass and drought-tolerant shrubs. After the sand settles and does not flow into the soil, trees and crops are planted.

The result of afforestation is to regulate the local climate, bring rain, reduce wind and sand, and increase air humidity and oxygen content. The most important thing is to prevent soil erosion, and make the area livable!

Trees are a great resource in their own right, they also protect against wind, fix sand dunes, purify air and water, and keep soil and water from eroding! It also maintains the ecosystem and allows other plants and trees to flourish, which in turn brings a variety of resources and benefits to humans!

Planting trees in the desert can seal sand, fix sand, improve the living environment, reduce sand and dust, and also plant Chinese herbs suitable for desert growth, such as Cistanche, sand dates, licorice, etc., to improve the lives of local farmers and herdsmen!

Protect the ecology, improve the living environment of the local people, fill the country's grain imports from abroad, and ensure national food security.

The greatest benefit is to increase the available land and water into Xinjiang, turning China's desert into an oasis completely.

Planting trees in the desert can keep the land moist and improve the dry climate.

Desert ecosystems are the most drought-tolerant on the planet, with super-xerophytic communities of small trees, shrubs and semi-shrubs predominantly and their surroundings. Deserts are stony, gravelly, and sandy. It is customary to call the stony and gravel desert the Gobi and the sandy desert desert desert.

The functions of desert ecosystems mainly include water and water conservation, soil and water conservation, water and air purification, nutrient element cycling, material production, pollutant degradation, organic matter, precipitation interception, water conservation, soil C accumulation, farmland ecosystem services, tourism services, unit area and regional ecosystem service value.

The only way to green the desert is to plant grass and trees.

DU afforestation. Only in this way can the DAO ecological environment be changed. Planting grass seems to be easy, but it is not as good as planting.

The effect of trees is obvious because the roots of trees are more absorbent and drought tolerant than grass roots. For example, poplar is recognized as a cold-tolerant tree species in desert areas, and others include sand willow, sea buckthorn, grapes, apricots, begonias, etc. These plants not only have the role of windbreak and sand fixation to conserve water, but some tree species also have economic value, such as killing, its vitamin C content is very high, grapes and apricots can create a certain economic income for people.

There's a lot of room to grow.

The greening of deserts should be carried out gradually, with suitable trees in the right places. It is easy to succeed in a step-by-step and planned manner, not only to green the desert but also to have certain economic benefits.

The root cause of the formation and expansion of desertification is the anthropogenic destruction of desert ecosystems (including deserts, Gobi systems, grassland systems, forest systems and wetland systems in arid and semi-arid areas), and the result of the inherent stability and balance imbalance within the system caused by the intensive development and utilization of water resources, biological resources and land resources in the system. In the past, we planted trees and grasses to prevent desertification through biological and engineering measures, while destroying desert ecosystems and creating new desertified land with the other. In fact, it is precisely because of the destruction of desert ecosystems that although we have built the "Three Norths" shelterbelt and implemented the desertification prevention and control project, we have still not been able to curb the pace of desertification expansion as a whole.

It can be said that in the past half century, the real reason for the frequent sandstorms is not that there is too little artificial vegetation, but that the natural vegetation has been destroyed too much. The partial improvement of the small environment cannot offset the overall inversion of the large environment.

It is necessary to adjust the strategy of desertification prevention and control, from one-sided emphasis on the development of artificial vegetation to actively develop artificial natural tree, shrub and grass composite vegetation. From simply protecting oases to actively protecting entire desert ecosystems, including oases. Only by reconstructing the desert ecosystem can we fundamentally curb the momentum of desertification and expansion, reverse the passive situation in the work of desertification prevention and control and soil erosion control, and effectively improve the overall ecology and environment of northwest China.

Afforestation, turf mulching, construction of shelterbelts, and desert greening are effective desertification control methods. Desertification is a global problem, especially in arid areas, and combating desertification is a top priority. An important means of controlling desertification is desertification control, and effective desertification control in deserts requires afforestation, and afforestation is an important means of desertification control.

Afforestation in desert areas should choose tree species suitable for the local environment, such as poplar euphratica and tamarix, which can adapt to extreme environments such as drought and high temperature in desert areas. When planting, we should pay attention to the density of trees and the way of planting, so as to avoid excessive planting density leading to competition between trees and affecting the development of stool length. It is also necessary to pay attention to the protection of tree slips to avoid erosion by wind and sand and animal damage.

The turf cover in desert areas should choose grass species suitable for the local environment, such as sheep grass and Suaeda salsa, which can adapt to extreme environments such as drought and high temperature in desert areas. It is necessary to pay attention to the density of the turf and the way of planting, to avoid excessive planting density leading to competition between the turf, affecting the growth and development, and to pay attention to the protection of the turf. The construction of the shelterbelt needs to choose tree species suitable for the local environment, such as Salix and Tamarix, etc., and the width and density of the shelterbelt should be paid attention to to avoid being too narrow or too dense to lead to poor effect.

Desert greening can be achieved through artificial planting, natural restoration, etc., artificial planting needs to choose tree species and grass species suitable for the local environment, pay attention to the density of trees and turf and planting methods, natural restoration needs to protect the local ecological environment, reduce human interference, so that the process of natural restoration can be carried out naturally.

Desertification control requires scientific management, which includes the investigation and analysis of the environment in desert areas, the formulation of scientific desertification control plans, the implementation of desertification control programs, and the monitoring and evaluation of desertification control programs. Scientific management should strengthen education and propaganda for local residents, so that the named people can understand the importance of desertification control and actively participate in the work of desertification control. Desertification control requires the comprehensive application of various means and scientific management.

Only in this way can we effectively control desertification in deserts and realize desert greening and control.

Planting trees is an effective means for desert control, but it is necessary to choose tree species that are suitable for the local ecological environment in order to give full play to the best effect.

Planting suitable tree species in deserts can effectively improve the local ecological environment and alleviate soil erosion. Some trees and shrubs with windbreak and sand fixation and drought tolerance, such as Salix salix sinensis, Begonia apricot, Tamarix salix and poplar, can play a good role in sand fixation protection in the process of desertification. Some plants with low or creeping properties, such as Populus euphratica, Caragana and Artemisia, can also effectively maintain the ecological balance of desert areas.

It is important to note that the selection of tree species needs to take into account the balance between diversity and stability in the ecosystem. If only one alien species is introduced over a large area, it may cause disrepercussions to other local organisms and even disrupt the ecological balance.

Therefore, when carrying out desert control, scientific planning and rational design should be carried out according to the characteristics of the local natural environment and the integrity of the ecosystem, and diversified and comprehensive management measures should be taken to promote vegetation restoration and ecological protection.

Surely we should plant trees!

Afforestation is an effective method of desertification control in the desert area, but attention should be paid to the selection of appropriate plant species.

First of all, you should choose plants that are resistant to drought, salinity, and can resist wind and sand, such as poplar, tamarix, white thorn, poplar, etc. These plants have strong drought resistance and weathering resistance, and can grow in desert environments and play a role in sand fixation and soil conservation.

Secondly, it is necessary to take into account the local climate and soil conditions, and choose plants that are suitable for the local ecological environment. Growing plants in desert areas requires ensuring that they can take root and germinate, so attention also needs to be paid to nurturing the soil.

Finally, it is necessary to pay attention to the reasonable planting density and layout, avoid excessive dense planting and death, and it is recommended to adopt scattered and sparse planting.

In short, afforestation in desert areas is a very important project to control desertification, and attention should be paid to selecting suitable plant species, and taking reasonable planting methods and management measures in combination with local climate and soil conditions, so as to achieve the best effect of desertification control.
