What are the five principles of ecology?

1, the principle of making the best use of everything. For example: no abandoned agriculture, biogas utilization.

2. The principle of species diversity. For example: forest ecosystem, grassland ecosystem.

3. The principle of coordination and balance. For example, the Three-North Shelterbelt and the Desert Shelterbelt should be adapted to local conditions.

4. The principle of integrity. For example, the integrity of man and nature, the integrity of animals and nature.

5. Principles of systematics and engineering. For example: raising fish and ducks in rice fields and grazing in grasslands.

The following is the concept of ecology.

1. Ecology is a science that studies the relationship between biology and environment and its mechanism of action.

1. Living things need a certain amount of space, material and energy for their survival, activities and reproduction. In the process of long-term evolution, organisms gradually form special requirements for certain physical conditions and chemical components of the surrounding environment, such as air, light, moisture, heat, inorganic salts and so on.

2. All living things need different substances and energy and adapt to different physical and chemical conditions, which is the ecological characteristics of species.

Second, the rapid growth of population and the interference of human activities have caused great pressure on the environment and resources.

1. Human beings urgently need to master ecological theory to adjust the relationship between man and nature, resources and environment, coordinate the relationship between social and economic development and ecological environment, and promote sustainable development. The survival of any creature is not isolated.

2. There is mutual help and competition between individuals of the same species; Plants, animals and microecology.

Third, there are also complex relationships between creatures.

1. In order to meet their own needs, human beings constantly transform the environment, which in turn affects human beings. With the expansion and diversification of human activities. The relationship between human beings and the environment is becoming more and more prominent.

2. The scope of modern ecological research has been extended to the complex system of various types of ecosystems, including human society, except biological individuals, populations and biological communities. Population, resources, environment and other major problems faced by human beings are the research contents of ecology.
