What is the function of the forest? What are the four ecological functions of forest in disaster prevention and damage prevention?

Making oxygen: green plants are consumers of carbon dioxide and producers of oxygen. Usually one hectare of broad-leaved forest consumes 1000 kilograms of carbon dioxide and releases 730kg of oxygen a day.

Purify the air: experiments show that trees absorb all kinds of toxic gases in the range of low concentration, so that the polluted environment can be purified.

For example, one hectare of Cryptomeria fortunei forest can absorb 60 kilograms of sulfur dioxide per month. Canna, rose, cloves, chrysanthemums, ginkgo and acacia can also absorb sulfur dioxide.

Filter dust: the dust absorption capacity of forests is 75 times greater than that of bare land. A hectare of beech forest absorbs as much as 68 tons of dust in a year.

In addition, forests play a very important role in water conservation, soil and water conservation, wind and sand protection, climate regulation and so on.

Experience at home and abroad has proved that if a larger country or region has a forest coverage rate of more than 30% and a relatively uniform distribution, then the ecological environment of this country or region is relatively superior and the production of agriculture and animal husbandry is relatively stable.

"Typhoon", "torrential rain" and "debris flow" seem to be everyone's common memory of disasters. In recent years, the climate has also begun to show obvious changes. How should human beings face more and more extreme rainfall events, and how should we deal with ourselves? When you go out to play on holidays, while you are close to the landscape, you may also be in the middle of disaster risks. disaster prevention and rescue will be something that both adults and children must face. Follow the Luodong Nature Education Center to understand the flood control and disaster reduction services provided by the forest. Understand the mechanism and causes of soil and water disasters, and then find out how to prevent, reduce and avoid risks. From this day on, we will become top soldiers in disaster prevention, and disaster prevention is not difficult.

The small sloping land model will show the mystery of land water conservation.
