Which is the largest plain in China, the largest plain in China

The largest plain in China is the Northeast Plain.

China's four major plains include the Northeast Plain, the North China Plain, the Middle and Lower Yangtze River Plain, and the Guanzhong Plain. Among them, the largest plain is the Northeast Plain (350,000 square kilometers), the smallest plain is the Guanzhong Plain (about 40,000 square kilometers), the most economically prosperous is the middle and lower reaches of the Yangtze River Plain (160,000 square kilometers), and the most populous plain is the North China Plain (310,000 square kilometers).

The Northeast Plain is in the temperate and warm temperate ranges, with continental and monsoon climate characteristics. Summers are short, warm and rainy; Winters are long, cold and snowless. The monsoon alternates between winter and summer.

The average temperature in July is 21 26 and the average temperature in January is 24 9. 10 The active accumulated temperature above 2200 3600 decreases from south to north. The annual precipitation is 350 700 mm, decreasing from southeast to northwest.

Topography. The Northeast Plain is surrounded by foothill flood alluvial plains and plateaus, with an altitude of about 200 meters. The shape of the northern plateau is more obvious, and the southern part is strongly eroded and has a shallow hill appearance.

The aeolian sand landform in the southwest of the plain develops, forming an alluvial plain covered by large sand dunes. The northeast end of the plain is connected with the Sanjiang Plain along the Songhua River Valley.

Production status. The Northeast Plain is one of the only three black soil regions in the world, and the grain output of the four northeastern provinces (regions) accounts for one-third of China's total output, and it is an important production base of grain, soybean and animal husbandry in China, as well as an important base of steel, machinery, energy and chemical industry in China.

The Northeast Plain, also known as the Songliao Plain (in a broad sense) and the Kandong Plain, is one of the three major plains in China and the largest plain in China, located in the northeast of China, composed of the Sanjiang Plain, the Songnen Plain and the Liaohe Plain, spanning Heilongjiang, Jilin, Liaoning and Inner Mongolia four provinces and regions, located between the large and small Xing'an Mountains and the Changbai Mountains, from the middle reaches of the Nenjiang River in the north to the Liaodong Bay in the south, with a length of about 1,000 kilometers from north to south, a width of about 400 kilometers from east to west, and an area of 350,000 square kilometers.

The Northeast Plain is the largest plain in China, located in the northeast of China, spanning Heilongjiang, Jilin, a part of Liaoning and a small part of Inner Mongolia, between the Great and Small Xing'an Mountains and the Changbai Mountains, from the middle reaches of the Nenjiang River in the north to the Liaodong Bay in the south, with a length of about 1,000 kilometers from north to south, a width of about 400 kilometers from east to west, and an area of 350,000 square kilometers.

The largest plain in China is the North China Plain.

The North China Plain is located in North China, stretching from Shanhaiguan in the north, Cangzhou City in Shandong Province in the south, Taihang Mountains in the west, and the Bohai Sea in the east. It is the largest plain in China and one of the most important agricultural areas in the world.

The North China Plain is flat and extends northeast-southwest with a total area of about 400,000 square kilometers. There are many rivers in the plain, such as the Yellow River, the Haihe River, the Liao River, etc., which provide abundant water and irrigation conditions for the plain, making the North China Plain one of the most important grain production bases in China.

The North China Plain has fertile soil, suitable climate, abundant sunlight and moderate rainfall, which provides excellent natural conditions for the cultivation of crops. Wheat, corn, soybeans and other food crops are widely cultivated on the plains, and it is also a major production area for agricultural products such as vegetables and fruits.

North China Plain features:

1. Advantages of agricultural production: The North China Plain has flat terrain, fertile soil, suitable climate, sufficient sunshine and moderate rainfall, which provides good natural conditions for the planting of crops. It is one of China's important grain production bases, where wheat, corn, soybeans and other crops are widely grown, making important contributions to national food security.

2. Abundant water resources: There are many rivers and lakes in the North China Plain, such as the Yellow River, Haihe River, Taihu Lake, etc., which provide abundant water sources. These water resources provide reliable support for irrigation of farmland, industrial water and urban water supply in the cavity city, driving the development of the region.

3. Economic center status: The North China Plain has an important geographical location and convenient transportation, with large cities such as Beijing and Tianjin, and is also the location of many important industrial bases. The well-developed manufacturing, service and commerce industries here provide strong support for the regional economy and have an important influence on the country's economic development.

4. Rich cultural heritage: North China Beiyuanzi Plain is one of the birthplaces of ancient culture in China, with a long history and rich cultural heritage. For example, Beijing, located in the North China Plain, as the capital of China, has world-famous cultural landscapes and historical sites, such as the Forbidden City and the Great Wall, which attract many tourists to visit and visit.

The largest plain in China is the Northeast Plain.

China's four major plains include the Northeast Plain, the North China Plain, the Middle and Lower Reaches of the Yangtze River Plain, and the Guanzhong Plain, of which the largest plain is the Northeast Plain. China's four major plains are ranked by area: Northeast Plain (350,000 square kilometers), North China Plain (310,000 square kilometers), Middle and Lower Yangtze River Plain (160,000 square kilometers), and Guanzhong Plain (about 40,000 square kilometers).

The Northeast Plain (also known as the Songliao Plain) is located in the middle of Northeast China, with the Changbai Mountains and the Great Xing'an Mountains on the east and west sides of the plain, the Xiaoxing'an Mountains in the north, and the Liaodong Bay in the south. It is about 1,000 kilometers long from north to south and about 400 kilometers wide from east to west, covering an area of 350,000 square kilometers, making it the largest plain in China.

The Northeast Plain can be divided into three parts, and the Northeast is mainly formed by the alluvial waters of the Heilongjiang, Songhua and Ussuri rivers. The southern part is mainly the Liaohe Plain formed by the alluvial Liaohe River, the central part is the Songnen Plain formed by the alluvial Songhua River and the Nenjiang River, and the Northeast Great Plain is a plain surrounded by mountains and rivers and fertile fields for thousands of miles.

Water system conditions

The total area of lakes in the Northeast Plain is 3,800 square kilometers, accounting for about the total area of lakes in China. The mountainous area of this area is an area with frequent volcanic activity in modern times, so most of the lakes in the area are closely related to volcanic activity, such as Jingpo Lake in the upper reaches of the Mudanjiang River and Wudalianchi in Dedu County. Jingpo Lake is formed by a natural weir formed by basalt flow to intercept the riverbed of the Mudanjiang River and raise the water level, while Wudalianchi is a bead-shaped dammed lake formed by a lava flow from a volcanic eruption blocking the river.

There are large areas of lakes and marshes on the plains, as well as small lakes of different sizes, known locally as bubbles or salt bubbles. The genesis of these lakes is mostly related to recent crustal subsidence, low-lying terrain, poor drainage and river swing, and they have the characteristics of small area, gentle slope drop of lake basin, deep modern sediments, shallow lake water and high salinity, such as moon bubble and dragon tiger bubble. Northeast China is located in the temperate humid and semi-humid climate zone, with short, cool and rainy summers, and abundant water entering the lake.
