The ninth typhoon "Ma'an" pre dicted by the meteorological observatory this year has made landfall in the area from Zhuhai to Zhanjiang, Guangdong on the 25th. It is reported that the maximum wind force near the center reached level 12 when it landed, and there were many obstacles on the surrounding roads. Several trees had their branches blown off, and traffic signs were also blown to the ground. Many people said that Typhoon "Ma'an" was so powerful that they could not stand firmly in the wind, and it was even difficult to walk. They could feel obvious pain when the sand hit their legs. In fact, the destructive power of typhoons to the ecology is more serious, which can be judged from the following aspects.

The wind is so strong that trees and vehicle signs will be damaged. The wind force at the center of this typhoon was level 12, which means that the weight of the wind pre ssure on a plane perpendicular to the direction of the wind is equivalent to 230 kilograms. Such a large pre ssure can easily overturn an electric car, and street billboards and roadside signs can easily be overturned. They may be blown off and fall to the ground, and even many new trees may be uprooted. In addition, typhoons are often accompanied by heavy rains, especially in the center of the typhoon. Heavy rains of 200 mm a day are common, and in severe areas, the rain can reach more than 500 mm. The damage caused by heavy rains is not limited to the surface ecology. Landslides, floods, and high tides are all common geological disasters during typhoons.

In addition, typhoons will also damage the ecological environment, such as river ecology and forest ecology. High-intensity winds and heavy rains will cause imbalances in the original ecological environment, changes in the overall climate, sudden drops in temperature and humidity Any change will affect the normal operation of the ecological balance, which is likely to lead to the direct disappearance of a certain rare microorganism, or the creation of new species or viruses.

Whether it is an urban environment or a rural environment, typhoons will have a huge impact on climate, temperature, and humidity, and will especially cause serious damage to the growth of crops. They will not only directly destroy crops but also seriously damage them. It affects the soil and destroys the surrounding water sources, causing the soil quality to deteriorate in the next few years.
