What are the benefits of planting trees in the desert?

1, resist sandstorm and prevent desert expansion.

By planting trees in the desert, these planted trees can keep loose sand, weaken the wind in the desert area and stop the expansion of the desert. Because the wind speed can be reduced to 20% to 30% after passing through these windbreaks, planting trees in the desert can effectively resist sandstorms.

2. Maintain soil and water.

Arid and semi-arid areas are characterized by lack of water resources and windy, and people's destruction of land has gradually turned cultivated land into desertification land. Because an acre of land with trees can store about 20 tons more water than an area without trees, planting trees in the desert can improve water and soil and improve the ecological environment.

3. Produce economic benefits.

Trees can be planted in desert areas, bringing economic benefits. On the one hand, planting economic trees in the desert can create a large number of local labor and employment opportunities. On the other hand, roads in the desert can be protected by planting trees. For example, China protects the Tarim Highway by planting trees, which is beneficial to the exploitation and transportation of oil.

Extended data:

Tree species suitable for desert planting are: Populus euphratica, Selaginella, Polygonum Samueli, Salix psammophila, Elaeagnus angustifolia, Hippophae rhamnoides, Artemisia arenaria, Stipa arenaria, pineapple, desert rhubarb, cactus and so on. In addition, we should pay attention to the arrangement of trees when planting trees in the desert. If many trees are arranged in parallel and grass is planted, it will be beneficial to resist sandstorms.
