What places are there to the north of Qinling Mountains?

The Qinling Mountains, which straddle the central part of China, have a great difference in climate between the north and the south due to its huge barrier function, thus forming the dividing line between the north and the south of China. Its concrete manifestation is that most of the northern foot of the Qinling Mountains in the eastern monsoon climate zone of China has a temperate monsoon climate, while most of the southern foot of the Qinling Mountains has a subtropical monsoon climate. At the same time, Qinling Mountain is also the place where the isothermal line of zero degrees Celsius passes in January and the 800mm precipitation passes. This also determines that it has become the dividing line between subtropical zone and warm temperate zone in China's temperature zone, and the dividing line between young and middle-aged humid zone and semi-humid zone in dry and wet zone.

Due to the great influence of Qinling Mountains on climate, rivers in the north and south of Qinling Mountains in China show different hydrological characteristics. The rivers south of Qinling Mountains have no freezing period, and are rich in water and low in sediment concentration. However, the rivers in the north have a freezing period in winter, and the longer the freezing period goes to the north, the greater the sediment concentration in the river and the smaller the water volume.

The obviously different climate makes the natural landscape between the north and the south of Qinling Mountains very different. There are warm temperate deciduous broad-leaved forest and forest grassland-brown soil belt on the northern slope of Qinling Mountains and the Guanzhong Plain to its north, and mixed forest of deciduous broad-leaved forest and evergreen broad-leaved forest-yellow brown soil and yellow cinnamon soil belt on the southern slope of Qinling Mountains and the Hanjiang River basin to its south.

Due to the differences in geographical location, climate, soil and plants between the north and south of Qinling Mountains, there are obvious differences in agricultural production.

South of the Qinling Mountains, the average temperature in January is above zero degrees Celsius, and the annual precipitation exceeds 800 mm, which belongs to the subtropical humid area and crops can grow all year round. Good hydrothermal conditions ensure the development of rice and rape, and vegetables can be cultivated in the open field in winter. It is the main producing area of rice, wheat and rape, and the cultivated land is mainly paddy fields, and rice and wheat are double-cropped to triple-cropped every year.

North of Qinling Mountains, the average temperature in January is below zero degrees Celsius, and the annual precipitation is less than 800 mm, which belongs to the warm temperate and semi-humid area. Due to the low temperature in winter, it provides conditions for winter wheat to overwinter. The growth and quality of winter wheat are better than those in the south of Qinling Mountains, and the high temperature in summer is suitable for planting cotton, corn and rice. Therefore, warm crops are the main crops, and cultivated land is mainly buried. The scenery in winter is generally monotonous.

Southerners and northerners have obvious psychological differences, and people in different regions also have different personalities, which is closely related to the environment. Most northerners are bold, enthusiastic and extroverted; Southerners, on the other hand, are more delicate, steady, introverted and calculating. The reason for this difference is not because of the difference in brain structure or genetic factors between southerners and northerners, but because of the different geographical environment of life.

In the north of China, there are fewer mountains and more plains. Looking around, you can see Fiona Fang for miles or even hundreds of miles. So northerners are more open-minded and generous. On the contrary, in the south, there are fewer plains than mountains and rivers, and the topography is blocked by mountains and rivers, which is quite broken. Only now the plains are criss-crossed, surrounded by mountains, and the vision is confined in a narrow space. Southerners plough intensively on palm-sized land. In order to survive, they have developed a cautious thinking habit and are good at using existing resources to exert their intelligence. In addition, the climate difference between the north and the south has caused the psychological difference between the north and the south. The climate in the south is mild and humid, and all kinds of flowers and plants compete with each other, making southerners calm, peaceful, emotional and delicate. The climate in the north is cold and dry, windy and dusty, with frost and snow in the past six months. Therefore, people who have lived in the north for a long time have formed a calm, childlike and virtuous character.

Some environmental meteorologists have also demonstrated the influence of geographical environment on psychology and personality from another logic. They think that mountain residents have developed a character of loud voice, straightforward speaking and sincere treatment because of their vast land and sparse population and long-term pushing the door to see the mountains. Therefore, they have the saying that "people love mountains". The warm and humid coastal areas of rivers and lakes are full of vitality because of the humid climate and beautiful scenery. Therefore, the residents here are often sentimental and resourceful, so there is a saying that "love the water is wise". Due to the vast grassland and inconvenient transportation, the herdsmen living on the vast grassland of the factory are generous and hospitable. In cold areas, due to the lack of outdoor activities, people often get along with others in a narrow space, so they often have strong endurance and self-control. Eskimos living in the coldest place on earth have amazing control and are called "people who never get angry" in the world. On the contrary, people living in some parts of the tropical region often live and work outdoors in order to avoid the heat. Coupled with their backward culture and education, they are often bohemian and often fight for small things. It can be seen that the influence of geographical environment on people's psychology and personality is not a duck meeting-nonsense!
