"Land Resources" China's natural resources PPT courseware 5

Land is the root of mountains and rivers

Land is the foundation of all things

Land is the source of food and clothing for mankind

Land is the source of all wealth

All Wuhua Tianbao are native-born

Land is everything in the past and everything in the future

Let us cherish the land together, protect the land, rationally utilize every inch of land, and realize the harmonious coexistence between man and nature!

Activity 1: Can you tell which land use type is shown in the picture?

Cultivated land: The terrain here is low and flat, the soil is fertile, and the climate is humid. People grow rice, rapeseed and other crops here to develop the farming industry.

Woodland This is a mountainous area with complex terrain that is not conducive to farming. However, the climate is humid and the forests are dense, allowing for the development of forestry.

Grassland The water and grass here are fertile. People graze cattle and sheep here and develop animal husbandry.

Activity 2: Understand the characteristics of my country’s land resources

The total amount of land resources is abundant.

my country’s cultivated land reserve resources

Cultivated land reserve resources refer to land suitable for cultivation that has good natural conditions but has not yet been cultivated. Most of the arable land in our country has long been converted into cultivated land. Due to the large number of people and the lack of land and unreasonable reclamation, part of the existing cultivated land still needs to be converted into forests, grasslands or lakes. Therefore, my country has the potential to expand cultivated land. Not big. Moreover, except for the difficult-to-use land such as the Gobi desert and the rocky mountain alpine desert, there are very few truly unused wastelands in our country. The total amount of reserve land resources in the country is only more than 13 million hectares. Most of these suitable arable lands are natural grasslands and woodlands, and they are mainly distributed in remote areas such as the Northeast and Northwest.

Activity 3: Read maps and analyze the distribution of various land resources

Combined with the map of dry and wet areas in my country, the topographic map of my country, and the distribution map of main land use types in my country, analyze which type of dry and wet areas and which type of terrain farmland, forestland, and grassland are mainly distributed in?

Our country’s cultivated land is mainly distributed in the humid and semi-humid areas in the east. Let’s ask you to think about a few questions:

① Where are the distribution of paddy fields and dry land roughly bounded?

②Which iso-precipitation line is the distribution more consistent with?

③What are the causes of the difference in cultivated land between the north and the south in my country?

The south has a lot of precipitation and is a humid area.

The north has less precipitation and is a semi-humid area.

group discussion:

Based on the above information and existing knowledge, please briefly evaluate the advantages and disadvantages of my country's land resources from both advantages and disadvantages:

Excellent: The total volume is rich and the types are complete, which is conducive to diversified operations.

Disadvantages: per capita occupancy is small, the proportion of various land resources is unreasonable (little cultivated land and forest land, and the proportion of difficult-to-use land is large), insufficient reserve resources, and the contradiction between man and land is prominent.

We cherish and rationally utilize every inch of land and effectively protect cultivated land.

Protect limited arable land resources

What problems arise during the utilization of arable land resources?

What measures to take?

1. Promulgate laws:

"Land Management Law", "Grassland Law", "Forest Law" and "Basic Farmland Protection Regulations"

2. Basic national policy of land resources

Cherish and rationally utilize every inch of land, and effectively protect cultivated land
