Classification of the environment, classification of the environment

The concept and classification of the environment.

Category 1: Indoor normal environment.

Category II A: Indoor humid environment: an open-air environment in non-cold and non-cold areas, in direct contact with non-aggressive water or soil. Category 2B: An open environment in a cold and cold area, where there is no direct contact with water or soil.

Category III: Environments where de-icing salts are used; the environment of winter water level fluctuations in severe cold and cold regions; Beachfront outdoor environment.

Category IV: Marine environment. Minzor.

Category V: Environments affected by man-made or natural corrosive substances.

Environments can be categorized based on different characteristics and attributes, which we will take into account in detail below.

Classified by biome.

Summary. In summary, environments can be classified from different perspectives, and each classification can reflect important characteristics and attributes of the environment. In the process of environmental protection, we need to take corresponding measures according to the specific situation to protect the environment and maintain the survival and development of human beings.

1. Class I: indoor dry environment, permanent non-erosive still water immersion environment.

2. Category 2A: Indoor humid environment, open-air environment in non-severe cold and non-cold areas, environmental trembling in direct contact with non-erosive water or soil in non-severe cold and non-cold areas, and environment in direct contact with non-erosive water or soil below the freezing line in cold and severe cold areas.

3. Category 2B: alternating dry and wet environment, environment with frequent changes in water level, open-air environment in severe cold and cold areas, and environment above the freezing line in severe cold and cold areas in direct contact with non-erosive water or soil.

4. Category 3A: Severe cold and cold areas in winter water level frozen area environment, environment affected by de-icing eggplant brother salt, sea breeze environment.

5. Category 3B: saline soil environment, environment subject to de-icing salt, coastal environment.

6. Four categories: sea dust buried water environment.

7. Category 5: Environments affected by man-made or natural corrosive substances.

According to the type of environment, it can be divided into atmospheric environment, soil environment, marine environment, terrestrial water environment, biological environment and other types. 1. Atmospheric environment: refers to the physical, chemical and biological characteristics of the air on which organisms depend.

2. Soil environment: In fact, it refers to the soil sphere that is continuously covered on the earth's land surface. 3. Marine environment:

Refers to the total body of water of the vast contiguous sea and ocean on Earth. <

According to the type of environment, it can be divided into atmospheric environment, soil environment, marine environment, terrestrial water environment, biological environment and other types.

1. Atmospheric environment: refers to the physical, chemical and biological characteristics of the air on which organisms depend. The physical properties of the air mainly include temperature, humidity, wind speed, air pressure and precipitation, all of which are caused by solar radiation.

The chemical properties are mainly the chemical composition of the air.

2. Soil environment: In fact, it refers to the soil sphere that is continuously covered on the earth's land surface.

3. Marine environment: refers to the total waters of the vast and continuous sea and ocean on the earth. These include seawater, dissolved and suspended in seawater, seafloor sediments and marine life. It is the cradle of life and a treasure trove of human resources.

4. Land water environment: refers to the general term of dynamic water and static water on the land surface, also known as "land water", including various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, ice sheets, etc. It is one of the most important water sources for human life, and it is also the main component of water resources in various countries.

5. Biological environment: refers to the fact that other living organisms in the environmental factors are relative to the abiotic environment composed of physical and chemical environmental factors, which is synonymous with Zen and organic environment.

The type of environment.

The environment is a very complex system, and there is no unified classification system yet. Generally, it can be classified according to the subject of the environment, the nature of the environment, the scope of the environment, etc.

According to the main body of the environment, there are currently two systems, one is the main body of people, and other living and non-living substances are regarded as environmental elements. This type of environment is called the human environment. In environmental science, most scholars use this classification method.

The other is that organisms are the main body, and all natural conditions other than organisms are called the environment, which is the classification method adopted in general ecological literature.

According to the nature of the environment, the environment can be divided into natural environment, semi-natural environment, and natural environment after being destroyed by humans.

According to the scope of the environment, the environment can be divided into cosmic environment (or interstellar environment), earth environment, regional environment, microenvironment and internal environment.

Cosmic environment. Refers to the atmosphere.

Outer space is a new concept put forward in the process of human activities entering the space beyond the atmosphere and the earth's adjacent celestial bodies, and some people call it the space environment. The cosmic environment is composed of vast space and various celestial bodies and diffuse matter that exist in it, and it has a profound impact on the earth's environment. Solar radiation is the Earth's main source of light and heat, bringing life to the Earth's biological organisms and fueling the vast ecosystem of the biosphere.

normal operation. As such, it is the source of all energy on earth. Changes in solar radiation energy affect the Earth's environment. For example, sunspots.

There is a clear correlation between the amount of occurrence and the amount of rainfall on Earth. Moon.

and the gravitational effect of the sun on the earth to produce tidal phenomena, and can cause natural disasters such as storms and tsunamis.

The global environment. Refers to the atmosphere.

The troposphere, hydrosphere, pedosphere, lithosphere and biosphere, also known as the global environment. The global environment is particularly closely related to people and living things. Among them, the organisms in the biosphere are closely linked to the relationship between the various spheres on the earth, and promote various material cycles and energy conversions.

Regional environment. It refers to the natural environment that occupies a specific geographical space, which is formed by the cooperation of the natural sphere in different regions of the earth's surface. Different regions have different regional environmental characteristics and different biological communities.

Microenvironment. It refers to the small environment formed by the environmental differences caused by the subtle changes of one or several circles in the regional environment. For example, the mosaic nature of a biome is the result of the microenvironment.

internal environment. Refers to the environment between tissues or cells in an organism. It has a direct impact on the growth and reproduction of organisms.

For example, inside the leaf, the air cavity, air chamber, and ventilation system that are in direct contact with the mesophyll cells are all places where the internal environment is formed. The internal environment has a direct impact on the plant and cannot be replaced by the external environment.

This type of environment is called the human environment. In environmental science, most scholars use this classification method.
