Geographical dividing line, where is the geographical dividing line

It's in middle school geography textbooks!

The first line of the Qinling Mountains and the Huaihe River is the dividing line between the north and the south, the Heihe River in Heilongjiang and Tengchong in Yunnan are the geographical demarcation line of China's population, and the Daxing'an Mountains-Taihang Mountain-Wushan-Xuefeng Mountain are the boundaries of the second and third steps.

The Qinling Mountains and the Huai River, the geographical dividing line between the north and south of China, lie the Qinling Mountains, a mountain range that runs east-west in central China. The Qinling-Huaihe line is often said to be the geographical dividing line between the south and the north, and the north and south of this line are obviously different from each other in terms of natural conditions, agricultural production methods, geographical features and people's living customs.

These provinces in China are located in the south: Jiangsu, Anhui, Zhejiang, Shanghai, Hubei, Hunan, Jiangxi, Fujian, Yunnan, Guizhou, Chongqing, Guangxi, Guangdong, Hainan, Hong Kong, Macao and Taiwan.

These provinces in China belong to the north: Heilongjiang, Jilin, Liaoning, Beijing, Tianjin, Hebei, Shandong, Henan, Shanxi, Shaanxi, eastern Inner Mongolia, Jiangsu Central Plains Mandarin District, Anhui Central Plains Mandarin District.

The southern part of the country accounts for about 25% of the country's land area, and the population accounts for about 55% of the country's population, with the Han nationality accounting for the majority. There are more than 30 ethnic minorities in the region, with more than 50 million people, mainly distributed in Yunnan, Guizhou, Sichuan, Chongqing, Hunan, Guizhou, Qiong and other places, and the larger number is Zhuang, Miao, Yi, Tujia, Buyi, Dong, Bai, Hani, Dai, Li and other ethnic groups. Topography:

The topography of this region is high in the west and low in the east, and the terrain is interlaced with plains, basins, plateaus and hills. There are many rivers and lakes in the plain area, and the water network is vertical and horizontal, which has the characteristics of typical southern water towns. Crops:

Rice, hogs, citrus, tea, silkworms, sugarcane, aquatic and tropical crops. Minerals: copper ore, tungsten ore, mercury ore, tin ore, antimony ore, lead-zinc ore.

The northern region refers to the area north of the Huai River in the Qinling Mountains in northeast China, with an area of about 20% of the country and a population of about 40% of the country. The Northeast Plain, North China Plain and Fenwei Plain in the region are important agricultural areas in China. Culture:

The northern region has a long history and culture, many places of interest and historic sites, and is extremely rich in cultural tourism resources. Crops: spring wheat, corn, sorghum, soybeans, potatoes, sugar beets, etc.

Temperate fruits: apples, pears, peaches, apricots, persimmons, dates, grapes, etc. Minerals:

Coal, iron, oil, etc.

China's geographical boundaries mainly include: the geographical boundaries of population distribution: the topographic ladder boundary; topographic zone boundaries; climatic boundaries; river boundaries; 3. Boundaries of natural areas; natural area boundaries; boundaries of agricultural activities; administrative boundaries; the sea dividing line; Integrated Geographical Boundaries.

It is bounded by Heihe City in Heilongjiang Province and Tengchong County in Yunnan Province, with a large population in the southeast and a small population in the northwest. With the increase in the number of migrant workers in the city and the gradual decrease in the population in the northwest, the economic development and population density of the two regions have gradually widened the distance, and with the implementation of the "western development" policy by the state in recent years, the population of the Qiyin area in the western region has increased year by year.

The population density in the coastal areas is generally more dense than that in the inland, especially in the delta and estuary, such as the Haihe River, the Yangtze River Delta, the Pearl River Delta, etc., the population density will be greater, and the commerce in these places is more developed, the amount is large, and the climate is suitable.

The upstairs is good, and the basic wisdom is:

Dividing line between Asia and Europe: Ural Mountains - Ural River - Greater Caucasus Mountains - Turkish Straits.

Dividing line between Asia and North America: Bering Strait.

Dividing line between Asia and Africa: Suez Randa River - Red Sea.

Dividing line between Europe and Africa: Strait of Gibraltar - Mediterranean.

Dividing North and South America: The Panama Canal.

South America, Antarctic demarcation line: Strait of Magellan.

Dividing line between Europe and North America: Xiaoxia Gorge in the Danish Sea Section.

I'll give you the picture.
