The first is the integrity and health of the ecological chain, the water ecological chain is the basic element of the water ecology, and the premise of establishing a sound and healthy water ecological chain is to prevent and resist alien species, so as to build a successful water ecosystem.

With the rapid development of the economy, in order to meet the needs of all walks of life, the price paid by the ecosystem is too high, and the ecology of the earth has been seriously damaged, and it is difficult to recover in a short period of time by its own regulation. In such a situation, it is necessary to adopt the method of ecological restoration to rebuild the ecosystem. In the application process of ecological restoration technology, there are four main aspects of restoration: First, it is necessary to restore the function of the ecosystem and restore it to its original healthy state.
Second, restore the ecological structure and restore biodiversity to its intact state. Third, restore the sustainability of ecosystems so that they are resilient to external disasters and self-healing. Fourth, restore the cultural characteristics of the ecosystem, so that the local human environment can be closely integrated with the natural environment, and promote the harmonious development of man and nature.
Source control and pollution interception is a prerequisite for water ecological restoration and a strong guarantee for ecological restoration. Exogenous governance is the foundation, and endogenous remediation is the goal. The use of "habitat creation technology + aquatic plant planting technology + water quality regulation technology + operation and maintenance technology" to achieve "in-situ restoration of water ecology".
Taking the Wuhan Tanghu Lake Basin Comprehensive Treatment Project as an example, after completing the source control and interception on the shore, the problem of more than 95% of the pollutants entering the Tanghu Lake has been solved, and the remaining 5% of the pollutants entering the Tanghu Lake are absorbed by in-situ water ecology, and the black odor has been eliminated through 6 months of treatment, reaching the class standard in 9 months, and partially reaching the class III standard in 15 months.

Think about it, why do the vast majority of human beings live by water? In the past two years, why should we focus on the treatment of black and odorous water bodies?
Aquatic ecosystems provide many services to human beings, and ecosystem services refer to the natural environmental conditions and utilities formed and maintained by ecosystems and ecological processes. It not only provides human beings with physical goods, medicines, and raw materials for industry and agriculture, but more importantly, supports and maintains the life support system on earth. For example:
Provision services (e.g., provision of food and water), regulatory services (e.g., flood and disease control), cultural services (e.g., spiritual disability, recreation and cultural benefits), and support services (e.g., nutrient cycling that sustains the living environment of life on Earth).
Therefore, protecting the water ecology and protecting the water environment is actually to protect our survival environment, why water? By extension, why is there still air, earth, and sound? Because they run through all of our lives, they can't be separated, they can't hide, and they need to live.
Individuals may not think of it, but as an organization, it is not right. The bigger and more influential the organization, the more it should take on this responsibility, for example: China!
UN! WWF World Nature** will! And so on.

1. Water is an important compound that makes up living organisms.
2. Water can regulate body temperature and temperature.
3. Water can maintain a certain tension in the body, so that the animal can maintain a certain shape and live normally.
4. Water is a very loose body and solvent with a large number of nutrients and elements.
5. Water is an important carrier of biogeochemical cycles, especially the alluvial cycles, so the water cycle is also the driving force of geological change.

1. Water is the medium of all nutrients, and the circulation of nutrients and water are inseparably linked.
2. Water is a good solvent for substances, and plays a role in energy transfer and utilization in the ecosystem.
3. Water is one of the drivers of geological change, the loss of mineral elements in one place, and the deposition of mineral elements in another place often have to be completed through the water cycle.
4. Water is constantly moving and transforming in the huge system of water cycle, so that water resources are constantly renewed.
5. The water cycle maintains the dynamic balance of global water.
6. The water cycle carries out energy exchange and material transfer. Terrestrial runoff transports sediment, organic matter and salts to the ocean; The absorption, conversion and transmission of surface solar radiation alleviate the contradiction of heat budget imbalance between different latitudes.
7. Cause erosion, transportation, accumulation and other external forces, and constantly shape the surface shape.
8. The water cycle can have an impact on the quality of the soil.
9. Water is an important part of living organisms.
10. Water participates in a variety of chemical reactions in living organisms, such as photosynthesis, aerobic respiration, etc.

Ecological water refers to the water body that is closely related to the surface plant body of the earth, and is an important part of the earth's hydrosphere. The earth's hydrosphere can be subdivided into the atmospheric hydrosphere, the surface hydrosphere, the ecological hydrosphere and the underground hydrosphere.
The so-called original ecological water means that the water has the material that nourishes life, and under the condition of adapting to the external environment, it raises the living body, and then maintains and cares for life. Since the entire biological world was still in a primitive state of existence at that time, the water used by living beings could restore its original quality through its self-purification ability under natural conditions.
The 9,000-year-old Dagu Glacier Spring Water is the water that was frozen in the Dagu Iceberg more than 9,000 years ago and was sealed, and even if this water was used by living beings before it froze, it was restored to its original state through self-purification. Since then, it has been isolated from the world, has not been polluted in any way, has not been degraded, and therefore is the highest quality raw ecological and healthy water.

Water is the foundation of life, and it has an extremely important ecological role, so I suggest you take a look at Ecology, which has a lot of details, and there are many aspects, and I'm going to make a few brief points.
1.Important compounds that make up living organisms.
2.High heat of evaporation and specific heat capacity (regulates body temperature, air temperature, etc.).
3.So that the body can maintain a certain degree of tension (so that the animal can maintain a certain shape and can live normally)4It is a carrier and solvent for many nutrients and elements.
5.It is an important carrier of biogeochemical cycles, especially sedimentary cycles, so the water cycle is also a driving force of geological change (energy is the ultimate driving force).
Wait a minute.

Ecosystems require the most basic water, oxygen, sunlight, and three or more organisms to form the simplest biological chains.
The monosphere is the area on Earth where life is active, mainly in the range from a depth of 12 kilometers below sea level to an altitude of 10 kilometers above sea level. Almost everything that has life in the world is included in this range. >>>More
