Although it is a part of natural ecosystem, it causes lots of damages like: ecological environment deterioration, damage of production and life, losses of lives and property, damage traffic safety and harm to human health. We should try to prevent it with the ways like establish forecast system of sandstorm and improve environmental governance and environmental protection. Recommendations From this research report, we can find a nature rule that is if human cannot protect earth and make the ecological balance ourselves; earth will use its own way to make the balance.

But here is a problem that is normally the method of earth uses is more harmful for human than our own way. Reference list 2010 China drought and dust storms. 2010.
