"Facing Our Country's Environmental Problems" Face Unprecedented Challenges Together PPT Courseware

Part One: Causes of Environmental Problems in my country

1. Our country is in a stage of rapid industrialization and continued population growth.

2. Extensive economic growth mode and low technology and management levels have gradually tightened the relationship between people and the environment.

Extensive type

Growth mode of high input, high consumption, high speed, low output, low quality and low efficiency

Waste of resources and energy, damage to the ecological environment

Intensive

Low investment, low consumption, high output, high quality, high efficiency and high speed growth mode

Conducive to resource and energy conservation and environmental protection

Facing my country's Environmental Problems PPT, Part 2: my country's Main Environmental Problems

1. Soil and water loss: The area of ​​water and soil erosion in my country reaches more than 3.5 million square kilometers, which is approximately equivalent to 37% of the land area. About 5 billion tons of topsoil are lost every year, which is approximately equivalent to the removal of 1 cm of fertile soil from cultivated land across the country.

2. Desertification: my country’s desertified land area reaches more than 2.6 million square kilometers, accounting for about 27% of the land area.

3. Environmental pollution: Waste gas, waste water and solid waste in industrial production cause serious pollution to the natural environment. Air pollution, water pollution and urban garbage pollution are prominent problems. For example, my country's major rivers are polluted to varying degrees; more than one-third of urban river sections have deteriorated water quality and lost their functional functions; the water quality of large freshwater lakes and reservoirs is also generally poor.

Areas with serious soil and water loss in my country: Loess Plateau, Northeastern hilly and mountainous areas, Yunnan-Guizhou Plateau, upper reaches of the Yangtze River, and Jiangnan hills.

Natural reasons: loose soil, thin soil layer, etc.

Man-made reasons: indiscriminate deforestation, unreasonable agricultural and forestry farming systems, etc.

Combined with the content learned in seventh grade, the natural conditions of the Hulunbuir area will be explained from the following aspects.

Location: Located in the northeastern part of Inner Mongolia and west of the Daxinganling Mountains.

Climate: Temperate continental climate, with large annual and daily temperature ranges.

Precipitation: Located deep inland, precipitation is scarce.

Facing my country's environmental problems PPT, the third part: the harm of environmental problems

1. In recent years, increasingly prominent environmental problems have caused huge direct or indirect economic losses, which have seriously restricted my country's economic development.

2. Environmental problems endanger people's health, affect social stability, and become a major issue threatening the survival and development of the Chinese nation.

environmental governance

1. Measures:

Build sand barriers in moving sand dune areas; build artificial grasslands in desertified areas; build sand-proof forest belts on the edges of oasis, and establish farmland protection nets inside oasis; return farmland to forests and grazing areas in non-arable areas; and in pastoral areas with poor ecological environment Implement a grazing ban.

Lanzhou City, Gansu Province, has incorporated the control of Yellow River pollution into its 11th Five-Year Plan and invested nearly 7.5 billion yuan in comprehensive treatment of the Yellow River water. The newly built sewage treatment plant in the picture has greatly improved Lanzhou City's sewage treatment capacity and sewage treatment level.

2. Results:

The ecological environment in some areas has been improved, and the atmospheric environment in many cities and large rivers and lakes have been controlled. People feel that the vegetation has become lush, the air has become fresher, the river water has become cleaner, and nature is full of vitality.

Measures for ecological environment construction and environmental pollution control in my country

1. Ecological environment construction:

① Carry out the construction of protective forest projects. Green barriers have been built in coastal areas, riverside areas, and in the northeast, north, and northwest regions of my country.

② Vigorously carry out desertification control work.

③Implement projects such as closing hillsides for afforestation, returning farmland to forests, returning farmland to lakes, and returning farmland to grazing land.

2. Environmental pollution control: In view of the reality of serious water pollution in my country's "three rivers, two lakes and one pond" and other large rivers and lakes, as well as the occurrence of acid rain and serious urban air pollution in some heavy industrial areas, treatment work has been launched and gratifying results have been achieved .

3. The long-term and durability of environmental protection tasks: Environmental governance is a long-term and arduous task that requires the joint efforts of generations or even dozens of generations.
