The largest plain in the world is the Amazon Plain, which is equivalent to more than 340 Beijing.

We all know that the plains are very big, and there are many plains in our country. Northeast Plain is the largest plain in China, covering an area of 350,000 square kilometers. The largest plain in the world is the Amazon Plain, which is 16 times that of the Northeast Plain, equivalent to more than 340 Beijing. That is to say, if a house is 100 square meters. Then, the largest plain in the world is equivalent to 5.6 billion houses.

The first plain is 16 times larger than the northeast plain of China.

The largest plain in the world is the Amazon Plain: it is located in the north of South America, in the middle and lower reaches of the Amazon River, between the Guiana Plateau and the Brazilian Plateau, bordering the Andes in the west and the Atlantic Ocean in the east. It spans the territories of Brazil, Peru, Colombia and Bolivia, covering an area of 5.6 million square kilometers. It is the largest alluvial plain in the world. The Amazon rainforest has dense vegetation, many kinds of plants and rich endemic species. There are many kinds of animals, especially arboreal animals. Mineral deposits mainly include oil. The land is vast and sparsely populated, with a total population of about150,000, of which100,000 Indians live in dense forests. Since the 1960s, we have organized immigrants in a planned way, developed agriculture and animal husbandry, and exploited natural resources. Amazon highway has been built all over the country.

There are many kinds of plants in the Amazon Plain, with endemic species accounting for 1/3. It is estimated that there are about 800 million cubic meters of wood in the forest, accounting for about 1/5 of the world's total wood stock. Trees such as Myrtaceae, Rutaceae, Meliaceae, Lauraceae and Apocynaceae are dominant. Rich in mahogany, ebony, Lvmu, Brazil nuts, clover gum, milk wood, Brazil cherry, ivory coconut and other economic trees. Brazilian cherries can grow to 80 meters high, and the oil content of cherries is as high as 73%, which is much higher than sesame seeds and peanuts. Edible, with high economic value.

Amazon plain is not only the largest plain in the world, but also rich in natural resources. There are many wild animals living on it. There are more than 1600 species of birds alone, not to mention other animals. Among them, the Amazon python is the largest snake in the world, with a longest length of 6.3 meters and a weight of more than 225 kilograms. It is as thick as the trunk of an adult man, but most pythons are about 3 meters long. So the largest plain in the world is the Amazon Plain, and the largest snake in the world is also in the Amazon Plain.

There are more than 1200 different plants per square kilometer in the Amazon rainforest, where there are 1/5 plants and animals on the earth. However, due to the deforestation of tropical rain forests, at least one species disappears there every day. It is predicted that with the decrease of tropical rain forest, at least 500,000-800,000 species of plants and animals will be extinct in a few years.

Amazon is the river with the largest flow and the widest drainage area in the world. Rivers are winding, lakes and swamps are densely covered, floods occur in flood season, and drainage is not smooth. The estuary is 240 kilometers wide, and the flood discharge reaches 6.5438+0.8 million cubic meters per second, which is 654.38+00 times that of the Mississippi River. The displacement is so large that the sea water becomes lighter within the range of 160 km from the shore. There are more than 1000 known tributaries, of which 7 tributaries are more than 1600 km long. The fertile silt deposited under the Amazon River nourishes an area of 65,000 square kilometers, and its basin area is about 7.05 million square kilometers, almost twice that of any other big river basin in the world.
