What is the role of environmental ecology in solving current environmental problems

Environmental ecology plays an important role in solving current environmental problems, which is manifested as follows:

1.Help people better understand the interaction between nature and living things, so as to develop more scientific and reasonable environmental protection strategies.

2.It helps people to better manage and maintain ecosystems to ensure biodiversity and ecological balance.

3.Provide methods for analyzing and evaluating environmental pollution and other ecological and environmental problems, and provide a scientific basis for formulating relevant policies.

4.It can guide the assessment and monitoring of environmental impact in the process of environmental protection engineering design and implementation, and put forward corresponding improvement suggestions.

In addition, environmental ecology also establishes an ecological perspective, manages and protects the environment, and at the same time clarifies the migration and transformation of pollutants in the environment, and uses the self-purification ability of the ecosystem to eliminate environmental pollution. It also involves biological monitoring and biological evaluation of environmental quality, provides a basis for the formulation of environmental capacity and environmental standards, and plays a role in environmental impact assessment, pollutant purification, and comprehensive utilization of resources and energy.

Therefore, environmental ecology is comprehensive and practical in solving current environmental problems, has very important significance for environmental protection, and plays an irreplaceable role in practice.

The research of environmental ecology focuses on the ecological principles and laws of environmental pollution, the comprehensive treatment of environmental pollution, the protection and utilization of natural resources, and the energy and resource utilization technology of waste, and the research aims to improve the deteriorating ecological environment, achieve the sustainable use of resources, and promote the sustainable development of economy, environment and human society The research object of environmental ecology is the impact of polluted environment on the entire ecosystem (mainly living organisms). It is the study of the interaction and reaction, opposition and unity between the organisms in the ecosystem and the polluted environment.

1. A series of interactive laws such as interdependence and mutual constraint, material circulation and metabolism, and the internal mechanisms that govern these laws. Therefore, the research objects of environmental ecology include not only the macroscopic study of the basic laws of the impact of environmental pollutants and human intervention on the individuals, populations, communities and ecosystems of organisms, but also the microscopic study of the toxic effects of pollutants and human intervention on the molecules, cells, tissues and organs of organisms and their mechanisms.

1. Ecological and environmental problems refer to the phenomenon that the structure and function of the ecosystem are seriously out of balance due to the destruction of the ecological level, thus threatening the survival and development of human beings.

2. Ecological and environmental problems can generally be divided into three categories:

1) Ecological damage caused by irrational exploitation and utilization of natural resources. It mainly includes the sharp decline of biological species, soil erosion, land desertification, etc.

2) Environmental pollution. For example, urbanization and the high development of industry and agriculture caused by the "three wastes" (wastewater, waste gas, waste residue) pollution, noise pollution, pesticide pollution, etc.; Global warming, acid rain pollution, ozone layer depletion.

3) Shortage of resources. Water shortage, land resource shortage, etc.

Ecological and environmental problems include soil erosion, land desertification, reduction of forest and grassland resources, and reduction of biodiversity.

From the perspective of discipline system, environmental ecology is an integral part of environmental science, but according to the discipline division of modern ecology, it is a branch of applied ecology, which is still in the stage of development and improvement.

Environmental ecology is an emerging and highly comprehensive discipline, which is a science that uses ecological theories to study the internal change mechanism, laws and counter-effects of ecosystems under human interference, and seeks countermeasures for the restoration, reconstruction and protection of damaged ecosystems.

Environmental ecology refers to a science that studies the relationship between organisms and the environment subjected to human intervention and its regularity based on the basic principles of ecology and the research results of systems science, physics, chemistry, instrumental analysis, environmental science and other disciplines. From the perspective of discipline development, the theoretical basis of environmental ecology is ecology, which is a branch of ecology, but at the same time different from ecology.

Environmental ecology is a science that studies the internal change mechanism, law and counter-effects of ecosystems under human interference, and seeks countermeasures for the restoration, reconstruction and protection of damaged ecosystems, that is, the use of ecological theory to elucidate the interaction between humans and the environment and the ecological ways to solve environmental problems.

Population ecology in environmental ecology can be used as a theoretical basis for studying population problems. The age structure and sex ratio of an area's population play an important role in the future numbers and trends of the region (or population, as it may be called).

Generally speaking, the main task of ecological engineering is to restore the damaged ecological environment (or damaged ecosystem), improve the production mode that causes environmental pollution and damage, and improve the productivity of the ecosystem. Ecological agriculture is an agro-ecological economic complex system, which integrates the agricultural ecosystem with the agricultural economic system to achieve the greatest overall benefits of the ecological economy It is also a large agriculture that integrates agriculture, forestry, animal husbandry, sideline and fishery industries, and is a modern agricultural agriculture that integrates agricultural production, processing and marketing to adapt to the development of the market economy The basic principles of ecological engineering include the principle of material recycling, the principle of species diversity, the principle of coordination and balance, the principle of wholeness, and the principle of systematics and engineering The purpose of establishing this artificial ecosystem is to realize the multi-level utilization of energy, improve the utilization rate of energy, and reduce environmental pollution

1) Generally speaking, the main task of ecological engineering is to restore the damaged ecological environment (damaged ecological environment), improve the production methods that cause environmental pollution and damage, and increase the productivity of the ecosystem

2) The purpose of ecological engineering construction is to follow the law of natural material circulation, give full play to the production potential of resources, prevent environmental pollution, and achieve the simultaneous development of economic (ecological) benefits and ecological (economic) benefits

3) Ecological economy is mainly through the implementation of the principle of circular economy, so that the pollutants produced by one system can become the production raw materials of this system or another system, so as to realize the resource utilization of waste

4) In the process of returning farmland to forest and grassland, it is necessary to pay attention to the tree species and grass species not to be too single, which is mainly based on the principle of ecological engineering is the principle of species diversity, and its purpose is to improve the stability of the ecosystem's resistance In the construction of ecological engineering, many production systems are organically integrated together through optimal combination to become a new and efficient ecosystem, which mainly follows the principle of systematics and engineering (the structure of the system determines the function) of ecological engineering

The application of ecology in environmental protection is mainly the application of pollution ecology. Pollution ecology is a new sub-discipline of ecology, which was born on the basis of many ecologists gradually shifting the focus of research to the interrelationship between organisms and the polluted environment. Pollution ecology provides an important theoretical basis for environmental problems from the perspective of ecology, and provides some practical means in environmental monitoring, evaluation and governance in environmental protection, among which the main ones are:

1) Biological monitoring and evaluation of environmental quality. The use of organisms can be used to monitor and evaluate the quality of the environment. Biological monitoring and evaluation is a means to judge the type of pollutant substances and the degree of pollution by using the response of organisms to pollutants in the environment, that is, the use of various information sent by organisms in various polluted environments.

Biological monitoring and evaluation is not only a means of monitoring and evaluation of environmental quality, but also a very important part of environmental quality and evaluation. (2) Use the self-purification ability of the ecosystem to eliminate environmental pollution. Pollution ecology proposes that the self-purification ability of ecosystems can effectively eliminate environmental pollution without physical and chemical methods.

3) Clarify the migration and transformation of pollutants in the environment. Pollution ecology believes that pollutants are not static in the environment, but are constantly migrating, transforming and accumulating with the material cycle of the ecosystem. Studying the migration and transformation of pollutants in the environment will help to understand the harm of pollutants to the environment and its consequences.

4) Provide a basis for the formulation of environmental capacity and environmental standards. Environmental capacity refers to the total number of pollutants that can be accommodated by the environment below the threshold of ecology and human health. Environmental capacity is one of the main bases for setting environmental standards.

Through the study of pollution ecology, the threshold value of pollutants on biological and human health can be provided, so that the environmental capacity and environmental standards of such pollutants can be formulated. (5) Conservation and rational utilization of biological resources. Using the basic principles of pollution ecology, the ecological threshold of each ecosystem is determined, so that human beings can not only maximize the use of biological resources within the scope of the ecological threshold, but also better protect biological resources.

For example, in a small mountain village, snakes can eat mice, but snakes are very deadly to humans, so humans organize an operation to eliminate snakes, and the snakes in the village are almost extinct. What humans didn't expect was that there were no snakes, and the sudden increase in the number of rats brought about a rat plague, and the dealer was gone, and the income was gone. At this time, human beings thought about the role of snakes and realized the importance of snakes in the ecology.

As a part of the ecosystem, the elimination of snakes changes the dynamic balance of the whole system, resulting in rat plagues, and human beings will suffer even if they are not threatened by snakes, so we must first apply a holistic perspective to solve ecological problems.

Nature as a whole is an interdependent community. The least complex life forms have the effect of stabilizing the entire biome. Every living "screw and gear" is important for the healthy functioning of the earth.

Human life maintenance and development depend on the dynamic balance of the entire ecosystem, so the core idea of ecology is a holistic view.
