"Population and Race" Residents and Settlement PPT Courseware 8

teaching objectives:

1. Understand the changing trends of world population, and master the problems and countermeasures caused by too fast or too slow population growth.

2. Learn to calculate the natural population growth rate and population density.

3. Understand the characteristics of world population distribution.

4. Remember the three main human races and their geographical distribution in the world.

1. Growth of world population

Question 1: Do students know how many people there are in the world now?

1. Large population

On October 12, 1999, the world's population reached 6 billion. In March 2006, the world's population reached 6.5 billion. The latest data shows that as of October 31, 2011, the world's population has reached 7 billion.

Question 2: How does the total population of the earth change?

2. Characteristics of population growth:

Slow growth--1800--rapid growth

3. Population changes

Calculation of natural population growth rate

Birth rate - death rate = natural growth rate of population

What do the natural population growth rates >0, =0, and <0 mean respectively?

>0, indicating that the population is increasing. The larger the value, the faster the growth.

=0, indicating that the population neither increases nor decreases, that is, the population stops growing.

<0, indicating that the population is decreasing. The larger the absolute value, the faster the decrease.

2. Distribution of world population

1. Population density

Refers to the average number of people living per square kilometer (person/square kilometer)

Population density = number of people in a certain area/total area of ​​the area (square kilometers)

Discussion: Why are populations concentrated in these areas?

From the latitude position: They are all located at ________ latitude

Judging from the location of land and sea: they are all located in the _________ area

Judging from the topography: They are all located in the _________ area

3. Population issues

1. Problems caused by excessive population growth.

(1) Resources are destroyed and the environment deteriorates
