The distribution of the population can be expressed in terms of

The situation of population distribution can be expressed in terms of population density.

Our population is 3 times the average population density of the world.

The boundary between the upper and middle reaches of the Yellow River is Tuoketuo (Hekou Town) in Inner Mongolia, the boundary between the middle and lower reaches of the Yellow River, and Taohuayu in Zhengzhou, Henan

1.The distribution of the population can be expressed in terms of square kilometers (how many people per square kilometer).

2.Our population is 3 times the average population density of the world.

3.The boundary between the upper and middle reaches of the Yellow River is Mengjin, and the boundary between the middle and lower reaches is at the estuary.

Refer to "History and Society", the world we live in, the first volume of the seventh grade).

1.Concept of population distribution +2The Concept and Formula of Population Density +3The main factors influencing the distribution of the population.

Population distribution refers to the spatial existence and distribution of the population in a certain period of time, including the distribution of the total population in various regions, as well as the distribution of some specific populations (such as urban wide pants population, specific population processes and compositions (such as migration, gender, etc.). Population distribution is the result of a variety of natural, social, economic and political factors. Natural environmental conditions (e.g., latitude, altitude, distance from the sea, etc.) play an important role in population distribution.

Since the 20th century, with the acceleration of industrialization and urbanization around the world, social, economic and political factors have had an increasing impact on population distribution.

The distribution of the world's population is mainly affected by the natural environment and socio-economic conditions such as topography and climate

So the answer is: natural environment; Economic conditions

It couldn't be less.

Make up 30 words yourself.

The distribution of the world's population has the following characteristics:

1. The biggest feature of population distribution is imbalance.

2. It varies regularly with latitude, altitude and distance from the sea.

3 Population distribution tends to lag significantly behind the development of productive forces and the shift of economic centres.

Low and middle latitudes! to the south of Europe, to the east of Asia. Wait!

The widening of income inequality is related to the reform of the income distribution system. Since the reform and opening up, with the reform of the income distribution system, the planned economic system"Egalitarianism"、"Big pot rice"The distribution system has been broken, and a distribution system with distribution according to work as the main body and the coexistence of various distribution methods has been gradually formed, which has played an important role in mobilizing people's enthusiasm for labor, promoting economic and social development, and improving the efficiency of resource allocation. But at the same time, the widening income gap between people naturally leads to the acquisition of books.

In particular, allowing factors of production such as capital, technology, and management to participate in the distribution according to their contributions will inevitably lead to a widening of income disparities due to differences in the quality and quantity of factors of production such as capital, technology, and management owned by members of society. In particular, in recent years, the proportion of labor in income distribution has dropped significantly, and the proportion of hidden factors of production, such as capital, technology, and management, has increased significantly, further widening the income gap between ordinary laborers and investors and managers.

China's population distribution is more in the southeast and less in the northwest, and the geographical distribution line of the population is the first line of Tengchong in the middle of the Heipeikai River According to the title

Therefore, the answer is: more in the southeast, less in the west and less in the north; Heihe--Tengchong

The correct answer is A

B is wrong, such as the Amazon plain rainforest climate, uninhabited.

cFalse, already inhabited.

D False, Africa is not densely populated, but concentrated.

Good luck with your studies!

a Europe and eastern North America are highly industrially developed due to their early industrial development and developed economy and dense population.

Europe is the West.

b The eastern part of Yahuimin Prefecture and the southern part of Yahuimin Prefecture were densely populated due to the early development of agriculture, and agriculture in the area was dominated by large-scale mechanization at one time.

Agriculture in these areas is not dominated by large-scale mechanization.
