What is the largest grassland on Earth?

The largest steppe on Earth is the Eurasian steppe.

The Eurasian steppe passes through a lot of places, the lower reaches of the Danube River is its starting point, from the east to expand, Romania, Russia, Kazakhstan it has passed, to our China from Mongolia to our northeast, the north is connected with the forest, and the south is close to a desert, from the southeast of our country to the southwest of the Qinghai-Tibet Plateau.

Due to the differences in the changeable ecological environment and geographical environment, this grassland can be divided into three sub-regions, the first is the Black Sea-Kazakhstan sub-region, which is the western half of this grassland, because of the influence of the geographical environment here, the spring here is very suitable for the growth of plants, so this area in the spring and autumn period of plant growth is particularly fast, especially short-lived plant lines.

Supplement the formation of the Eurasian steppe, as shown below:

The Eurasian steppe region is the largest steppe region in the world. From the lower reaches of the Duo Nao River in Europe, through Romania, Russia, Kazakhstan and Mongolia, it goes directly to the northeast of China. The east and west stretch for 110 degrees of longitude.

It is bordered to the north by a cold-temperate coniferous forest belt, and to the south by the Eurasian desert. It is about 45 degrees north latitude between 55 ° N. It roughly extends to the northeast of China in an east-west direction, and turns to the southwest to the south of the Qinghai-Tibet Plateau due to the southeast of China's coastal area.

The representative type of the Eurasian steppe region is the clumping grassy steppe of various needle-building groups. The Eurasian steppe region is further divided into three subregions, namely the Black Sea-Kazakhstan sub-region, the Central Asia sub-region and the Tibetan Plateau sub-region. The Black Sea-Kazakhstan sub-region is located in the western half of the Eurasian steppe region, and its eastern boundary is roughly consistent with the border between Xinjiang and Kazakhstan in China.

Central Asia is located in the northeast of the Eurasian steppe region, mainly including the Mongolian Plateau, the Songliao Plain and the Loess Plateau. Due to the drought in spring, there is only one peak growth in summer throughout the year, and there is a lack of spring short-lived and quasi-short-lived plants. The subregion of the Qinghai-Tibet Plateau is the highest grassland region in the world, which is an alpine grassland type, and often occurs in the community, and alpine cushion-like plants.

The Eurasian steppe region is not only the largest and most important on the planet, but also the best preserved steppe area at present.

The world's largest grasslands are the African savannah (including the East African savannah, the South African savannah and the West African savannah), the south-central South American savannah (including the Río de la Plata estuarine grassland, the Uruguayan grassland, the Pampas savannah and the south-central Brazilian savannah), the central North American savannah (across the United States and Canada) and the Australian annular prairie, and the fifth is the Eastern European grassland, the Mongolian grassland (including the Hulunbuir grassland and Xilin Gol grassland in Inner Mongolia and the eastern Mongolian grassland). There is a saying on the Chinese Internet that the four grasslands are the Hulunbuir Grassland, the Nalati Grassland, the Pampas Grassland, and the Xilin Gol Grassland, and all three are in China except for the Pampas Grassland. This is a ridiculous statement.

Anyone who knows a little bit of geography knows that the area of the tropical savannah in Africa is the largest, followed by the tropical savannah and temperate grassland of South America, and the temperate grassland of central North America (the largest and most high-quality temperate grassland in the world). The East Asian Mongolian steppe in Asia is the fourth largest in area, but most of the East Asian Mongolian steppe has an extremely dry climate, most of the steppe is desertified, desertified (semi-desertified), and many grasslands are abandoned; Moreover, the Xilin Gol, Hulunbuir and eastern Mongolian steppes in the eastern Mongolian steppe were originally connected to the eastern Mongolian steppe. However, the savannah and temperate grassland areas of the Australian circumtropical desert are sparsely populated and have good ecological protection, so the actual area of high-quality grassland is larger than that of the Mongolian grassland in East Asia.

As for the Nalati grassland, it is not a big grassland in the world, even in the Eurasian continent, it is really a small grassland.
