Environmental Air Quality Functional Zone Division Principle and Technical Method
1 Introduction
The environmental air quality functional zone division principle and technical method is the important basis for the construction of environmental air protection in our nation. It is mainly used to regionalize the marine environment to determine different management schemes in order to protect the environment from pollutants. This method can be divided into two categories, the first category is the principle of functional zoning and the second category is the technical method used for the zoning process. This article intends to provide a brief introduction about the two categories.
2 Principle of Functional Zoning
The principle of functional zoning mainly delineates the functions of the air protection zone according to different objectives or protection targets. This usually includes demarcating the protections of the aerial environment, land, water surface, and the population living near these protected areas. For example, some areas can be designated as repair zones that must be protected from contamination. Other areas may be used as resource utilization zones providing a clean and healthy environment for citizens to engage in outdoor activities.
3 Technical Method Used for the Zoning Process
Technical method used for the zoning process refers to the specific method of achieving the intended objectives of the zoning process. These methods include the setting of administrative boundaries, identification of the pollutant sources and their potential impacts, evaluation of existing environmental standards, data collection and analysis, modeling, multi-criteria analysis, GIS mapping, and decision-making.
Administrative boundaries define the area of jurisdiction for a certain control as well as the responsibility for the various agencies involved in the control of air pollution. Identification of the pollutant sources and their potential impacts allows the identification of areas of possible contamination and the assessment of the extent and duration of exposure to pollutants. Evaluation of existing environmental standards defines the limits at which pollution and contamination can be considered acceptable. Data collection and analysis involves the collection and analysis of both traditional and emerging data sources in order to inform decisions about the zoning process. Modeling can be used to predict the spatial and temporal spread of air pollutants with the aim of identifying areas of potential concentration. Multi-criteria analysis is used to compare a set of objectives and criteria in order to identify the most suitable solution. Finally, a GIS mapping tool can be used to visualize the results of the zoning process and to provide a decision-making platform.
4 Conclusion
It is important to understand the principle of functional zoning and the technical methods used for the zoning process in order to achieve successful implementation of the zoning process and achieve the desired objectives. Without an understanding of the principle and the technical methods, it will be impossible to effectively implement the zoning process. Therefore, it is essential to understand both of these components in order to effectively and efficiently manage air pollution and the protection of the environment.
