The Dazu mountain fire in Chongqing has been initially controlled. What impact does the mountain fire have on the local ecological environment?

Due to the continuous high temperature and dry weather, forest fires have occurred in many places in Chongqing. Armed police, fire fighting, emergency rescue and even people from all walks of life are actively involved in the rescue work, and they are all doing their part to contribute to the suppression of mountain fires. At present, the mountain fires in Mawu, Fuling District, Zhuxi Village, Kaizhou District and Yanshan Township, Wanzhou District have been basically extinguished, and the fires in Dazu and Tongliang have been initially controlled. All localities are still cleaning up the remaining fires, preventing rekindling and carrying out material rescue work. In fact, mountain fires have a great impact on the local ecological environment:

First, forest fires will first burn down trees, leading to a sharp decline in forest area and affecting the future growth of trees. Because the recovery period of trees is very long, if forest fires occur repeatedly, the soil in this area will be affected, even become barren, the ecological environment will be seriously damaged, and a series of changes such as local climate and humidity will be triggered.

Besides trees, there are many other microorganisms and wild plant resources in the second forest, some of which are even unknown species. Some of these pollution-free rich resources can be used as medicine, some can be made into green food such as wild fruits, and some can also provide research data for scientific research. Once a fire breaks out, these resources will not only be directly burned, but also change their living environment, leading to their reduction or even extinction.

There are also many wild animals in the third mountain forest. The occurrence of mountain fires may directly kill these animals and destroy their living environment. Many wild animals in China are facing extinction, such as Xinjiang tiger, Northeast tiger, giant panda, gibbon and golden monkey. Fourth, forest fires will cause a lot of soil erosion, because trees have a certain water storage capacity, which will destroy the storage capacity of trees for water in the soil after the fire. Finally, mountain fires will produce a lot of smoke, including carbon monoxide and hydrocarbons, which will cause air pollution.
