1, environmental impact prediction: by analyzing the possible environmental impact of the project, predict the degree and trend of environmental impact after the project is implemented.
2. Environmental risk assessment: assess the possible risks and probabilities of the project to the environment and human health, and formulate corresponding risk management measures.
3. Ecosystem assessment: Assess the impact of the project on the ecosystem, including species diversity, community structure and ecological process.
4. Hydrogeological evaluation: evaluate the impact of the project on water resources and geological environment, including groundwater, soil erosion, floods, etc.
5. Social impact assessment: assess the impact of the project on social economy, culture, history and population migration.
6. Health impact assessment: assess the impact of the project on human health, including noise, air pollution, water pollution and electromagnetic radiation.
Methods can be used alone or in combination to comprehensively evaluate the possible environmental impact of the project.
Environmental impact assessment can be defined as the process of predicting the environmental consequences of project development. Environmental impact assessment aims at evaluating and expressing the impact of any available method on the environment in the decision-making process, and is an important method to ensure the survival of personnel under environmental conditions.
Environmental impact assessment is a method and system to analyze, predict and evaluate the possible environmental impact after the implementation of planned construction projects, put forward countermeasures and measures to prevent or mitigate adverse environmental impacts, and conduct follow-up monitoring.
Environmental impact assessment is a quantitative and qualitative evaluation method, which is used to evaluate the potential impact of construction or development projects on the environment.
Principles of environmental assessment:
1. Transparency: All evaluation bases and decisions must be open and feasible.
2. Confirmation: The timetable and procedures of the project or evaluation should be approved in advance and all participants should abide by them.
3. Participation: All locations can use the plan in a timely and appropriate manner.
4. Practicality: The project or evaluation procedure should provide results and information, and can be used for decision-making and planning.
5. Flexibility: The project or evaluation procedure should be able to make changes and effectively handle suggestions and decisions.
6. Economy: The project or evaluation procedure and its results can ensure the society to carry out environmental protection at the lowest cost.
7. Credibility: Professional evaluation should be conducted according to the objectives.
8. Responsibilities: Team leaders or decision makers should be responsible for the actions and decisions of all parties in the evaluation process.
