Embodiment 1

[0048] The invention provides a method for characterizing the change of the heavy air pollution process, the method comprising:

[0049] (1) Define the index system, unit scale, and grading standards that characterize changes in air pollution; specifically:

[0050] (11) Based on the pollutant items and air quality index stipulated in my country's ambient air quality standards, the pollutant items mainly include: SO 2 , NO 2 , CO, O 3 , PM 10 , PM 2.5 , the air quality index is AQI. One of the indicators can be used to evaluate the air pollution status, and all the indicators can be used to evaluate the air pollution status. Therefore, this patent defines 8 index systems that can characterize changes in air pollution:

[0051] a.[SO 2 ]

[0052] b.[NO 2 ]

[0053] c.[CO]

[0054] d.[O 3 ]

[0055] e.[PM 10 ]

[0056] f. [PM 2.5 ]

[0057] g.[AQI]

[0058] h.[SO 2 , NO 2 , CO, O 3 , PM 10 , PM 2.5 , AQI]

[0059] (12) Define the unit scale of the polluti...

Abstract

The invention provides a method of representing atmosphere heavy pollution process changes. According to the method, first, an indicator system, unit dimensions, grading standards and other measurement standards representing atmosphere pollution changes are defined; second, according to the standards, a positioning method for the atmosphere heavy pollution process is put forward, and information such as specific change characteristics and weather influential factor characteristics is extracted in the heavy pollution process; last, a needed basic bottom table frame is established, and the extracted information is subjected to description marking under the frame to realize description of the heavy pollution change process.

Description

technical field [0001] The invention relates to the technical field of environmental big data mining, and more specifically, to a method for characterizing changes in the process of heavy air pollution. Background technique [0002] Heavy air pollution occurs frequently in our country, and its formation is inseparable from factors such as meteorology, topography, and emissions, and the influence relationship is intricate. Based on a large amount of environmental data, it is an indispensable technical research to control heavy air pollution by digging out the knowledge of the characteristics of the heavy pollution process and the relationship between the influences, and making analysis and decision-making. However, in the current research, general methods such as tables and time series curves are often used to extract and analyze the heavy pollution process, which makes it difficult to deeply represent the knowledge of the heavy pollution process, and it is also difficult to ...
