The strongest sandstorm in the past decade hits, why does the protective forest not work?

Large-scale sandstorms occurred in cities in northern my country. After some workers work outdoors for two hours, a layer of dust will become attached to their masks. The sandstorm that occurred in northern my country this time has been hailed as the strongest sandstorm in the past decade, which has led some people to question that the protective forest has not played a role. In fact, we cannot put all the blame on the failure of shelterbelts, and different planting years of shelterbelts will have different tree protective effects. What's more, unreasonable development by local residents will also affect the protective role of the shelterbelts. The large-scale sandstorms that occur in northern my country depend on the wind direction, wind force and weather conditions, and the connection between sandstorms and shelterbelts is subtle. Please do not Attribute all the blame to the failure of the protective forest to play its original role.

The first reason: the protective forest planting time is too short

The process of everything happening is not achieved overnight, and even the occurrence of many things is the result of a long period of evolution. Trees grow very slowly, especially in shelterbelts planted in areas with harsh conditions and in water-scarce areas. It takes about 15 years for most shelterbelts to form protective forests. A large number of shelterbelts are planted every year in our country. This may cause the newly planted shelterbelts to be unable to play a strong protective role, eventually leading to sandstorms in the northern region. The weather is coming.

The second reason: residents in different regions have different lifestyles

We can clearly find that the protective forests that have begun to take shape in some areas have been permanently damaged and cut down. Residents used certain means to cause the death of large areas of the shelterbelt and switched to planting grapes that require higher soil moisture. Although many media reported on this incident, no specific conclusion could be drawn. Perhaps the protective forests in some places have been irreparably damaged. After the protective forests are destroyed, no effective green barrier is formed in the local area, and huge amounts of sand and dust will follow.

The third reason: There are serious gaps in the shelterbelt planting chain

Everyone is pursuing higher personal interests. We cannot rule out that some staff members are planting shelterbelts in the process. , they put part of the funds into their own pockets, which led to a huge gap between the actual planted shelterbelt trees and the nationally prescribed shelterbelt trees. Ultimately, large-scale shelterbelts failed to prevent sand from entering northern cities.

In general, the failure of shelterbelts is closely related to people's planting methods and planting scale, and the age of planted trees.
