Why rainforests matter

Forests purify the air and regulate the climate, and tropical rainforests play a vital role in the environment. Tropical rainforest is mainly distributed in the north and south sides of the equator, where it is hot and humid all year round, the plants are luxuriant, can absorb a large amount of carbon dioxide in the air, release a large amount of oxygen, and have a great impact on the global climate, so the tropical rainforest is also known as the "lungs of the earth", in addition, the biological species in the tropical rainforest are extremely rich, among which there are more than 45,000 species of higher plants alone, and the rich plant species provide food and habitat for a variety of animals, As a result, it has become the richest region on the planet for fauna.

Introduce. Tropical rainforest is a forest ecosystem on Earth that is commonly found in tropical areas near the equator, mainly in Southeast Asia, northern Australia, the Amazon River basin in South America, the Congo River basin in Africa, Central America and many Pacific islands.

Tropical rainforest is the biological community with the highest resistance stability on the earth, the climate is hot all year round, the rainfall is abundant, the seasonal difference is very insignificant, the biological community succession rate is extremely fast, it is the habitat of more than half of the animal and plant species in the world, the tropical rainforest is undoubtedly one of the most valuable resources given by the earth to human beings. Since more than 25% of modern medicines are now extracted from tropical rainforest plants, tropical rainforests are known as the "world's largest pharmacy". At the same time, because the photosynthesis of many rainforest plants has a particularly strong ability to purify the earth's air, among which the Amazon rainforest alone produces 1 3 of the world's total oxygen, so it has the reputation of "the lungs of the earth".

The main role of tropical rainforests is to regulate the climate, prevent soil erosion, purify the air, and ensure that the material circulation of the earth's biosphere is carried out in an orderly manner.

Formation conditions. An evergreen forest biome rich in thick-stemmed vines, woody and grassy epiphytes that occur naturally in the warm and rainy tropics. The superior and stable environment provides the best conditions for the survival and development of tens of thousands of biological species.

Tropical rainforests grow mainly in the humid tropical lowlands with an average annual temperature of 24 or more, or the coldest month with an average temperature of 18 or more. The temperature is generally around 30 during the day and about 20 at night.

In terms of climate type, a certain amount of tropical rainforest can be formed under tropical rainforest climate, tropical oceanic climate and tropical monsoon climate, and the tropical rainforest formed under tropical rainforest climate is the most typical.

The team found Cretaceous soils in forests 900 kilometers from Antarctica, and analyzed plant roots, pollen and spores in the soil to find that the world was much warmer 90 million years ago than it is now, when Antarctica was full of tropical forests. Antarctica also has tropical rainforests Researchers have found that 90 million years ago, there were signs of tropical rainforests in Antarctica.

Tropical rainforestsThe difference between the zone and the tropical monsoon forest zone is:

First, tropical rainforests are hot and rainy all year round, and leaves generally do not fall off; Tropical monsoon forests have a clear distinction between wet and dry seasons, when the main tree species lose their leaves and new leaves grow again during the rainy season.

Second, the tropical rainforest has a complex structure, which can be divided into 4 or 9 layers, with a wide variety of plants, and each species is relatively strong, and there is no obvious dominant species; Compared to tropical rainforests, tropical monsoon forests have a relatively simple structure, fewer plant species, and are often one species with a distinct advantage over others.

Thirdly, the competition of plants in tropical rainforests is cruel, and there are strangled plants, and the phenomenon of tabular roots, pillar roots and old stems and flowers is more common. There are no strangled plants in tropical monsoon forests, and the phenomenon of slab roots and old stems growing flowers is not common.

Fourth, the vegetation on the surface of tropical rainforest is not as much as that of tropical monsoon forest, and there are much more vine, epiphytic and parasitic vegetation in a single layer than in tropical monsoon forest.

Tropical rainforests are common equatorial tropical forest ecosystems on Earth, mainly found in Southeast Asia, northern Australia, the Amazon River Basin in South America, the Congo River Basin in Africa, Central America, and many Pacific islands. Rainforests are important because they are the most stress-resilient biomass on Earth. The climate is hot all year round, the rainfall is abundant, the seasonal differences are very insignificant, and the biome succession rate is extremely fast, which is the habitat of more than half of the animals and plants in the world.

Tropical rainforests are undoubtedly one of the most precious resources on Earth. Since modern medicine accounts for a quarter, the rainforest is known as the largest pharmacy in the world. At the same time, due to the photosynthesis of many rainforest plants, the ability to purify the earth's air is particularly powerful, among which the Amazon rainforest alone produces one-third of the world's total oxygen, so it has the reputation of the lungs of the earth.

The main role of tropical rainforests is to regulate the climate, prevent soil erosion, purify the air, and ensure that the material circulation of the earth's biosphere is carried out in an orderly manner. Forests purify the air and regulate the climate, and tropical rainforests play a vital role in the environment. It is mainly distributed in the south and north of the equator, where it is hot and humid all year round, and the plants are abundant.

It can absorb a large amount of carbon dioxide in the air, release a large amount of oxygen, and affect the global climate. As a result, tropical rainforests are known as the lungs of the earth. In addition, the tropical rainforest is extremely rich in biological diversity, with four or five thousand species of higher plants alone.

The abundance of plant species provides food and habitat for a variety of animals, making it also the region with the richest animal variety on the planet. In the hot summer, the forest is refreshing and pleasant. Tropical rainforests have high biodiversity and rich biological resources.
