"my country's Green Ecological Engineering" PPT courseware
Part One: Sustainable Development
Sustainable development means meeting the needs of the present without compromising the ability of future generations to meet their needs. In other words, it refers to the coordinated development of economy, society, resources and environmental protection. They are an inseparable system, which must not only achieve the purpose of economic development, but also protect the atmosphere, fresh water, oceans, land and water on which human beings depend for survival. Natural resources and the environment, such as forests, enable future generations to develop sustainably and live in peace and contentment. Sustainable development and environmental protection are related but not identical. Environmental protection is an important aspect of sustainable development. The core of sustainable development is development, but it requires economic and social development under the premise of strictly controlling population, improving population quality, protecting the environment, and sustainable utilization of resources.
In order to protect plant resources and follow the path of sustainable development, our government has successively promulgated the "Forest Law of the People's Republic of China", "Grassland Law of the People's Republic of China" and "China Agenda 21", vigorously promoting the compulsory tree planting of all people, greening the motherland, and March 12th every year is designated as the "Arbor Day" across the country. Since 1978, our country has established more than ten large-scale ecological projects, giving our country a better resource foundation and broad prospects for the sustainable development of forest resources.
my country's Green Ecological Project PPT, Part 2: Construction Goals
The area of forest land increased from 23.14 million hectares to 60.84 million hectares.
The forest coverage rate increased from 5.05% to 15%.
The total storage of standing trees increased from 720 million cubic meters to 4.27 billion cubic meters.
The economic forest area expanded from 1.06 million hectares to 3 million hectares;
The annual output value of diversified operations reaches 10.7 billion yuan.
The annual forestry output value increased from 900 million yuan to 24 billion yuan.
All plains and oasis farmland have been transformed into forest networks, increasing crop yields by 10% to 15%. Soil and water are basically under control.
The sandy land has been controlled and the desertification area will no longer expand.
my country's green ecological engineering PPT, part three: matters needing attention in greening design
1. The actual situation of the school should be considered and no major changes should be made to the original design;
2. In view of the limited land area of the campus, more consideration should be given to three-dimensional space design to effectively utilize the space and present a three-dimensional hierarchy;
3. Pay attention to the growth cycle of flowers, plants and trees, and try to make the campus feel like spring all year round;
4. Campus greening design should also be careful not to hinder teachers and students from carrying out normal teaching, learning, activities, etc.
my country's Green Ecological Engineering PPT, Part 4: Summary of this lesson
The 21st century will be a century in which my country's society, economy, resources and environment enter a virtuous cycle of sustainable development. The ecological protection of forests will receive more and more attention from people. The sustainable development of forest resources has broad prospects. The construction of my country's top ten ecological projects will make the land of our motherland present a lush and beautiful scene.
Participating in afforestation and protecting every green leaf is the obligation of every citizen. We young people are the future of our motherland, and it is our responsibility to plant trees and grass and green our motherland. In order to protect the common home of mankind, let us start from ourselves, from now on, and from every little thing around us.
