Embodiment 1

[0077] The embodiment of the present invention provides a method for constructing an atmospheric pollution source map, such as figure 1 As shown, the method includes:

[0078] S1: Obtain pollution source data from multiple sources in the area to be constructed.

[0079] Take Beijing as an example for the area to be constructed, and obtain pollution source data from multiple sources in Beijing, including but not limited to emission inventory data, information data of pollutant discharge enterprises of the Law Enforcement Corps, POI data, and monitoring data of key sources.

[0080] POI data can include catering POI data, industrial POI data, auto repair POI data, dust construction site POI data, and breeding POI data, such as figure 2 shown.

[0081] S2: Based on the location of the pollution source, the degree of spatial aggregation and the emission of air pollutants in the data of each pollution source, establish a credibility evaluation system for the pollution source.

...

Embodiment 2

[0112] The embodiment of the present invention provides a kind of atmospheric pollution source map construction device, as shown in the figure, the device includes:

[0113] The data acquisition module 1 is used to acquire pollution source data from multiple sources in the area to be constructed.

[0114] Credibility evaluation system establishment module 2 is used to establish a credibility evaluation system for pollution sources based on the location of pollution sources, the degree of spatial aggregation and the emission of air pollutants in each pollution source data.

[0115] Screening module 3 is used to retain pollution sources with high credibility and filter out pollution sources with low credibility according to the inversion results of pollutant concentrations in the area to be constructed under the credibility evaluation system.

[0116] The classification module 4 is used to divide the retained pollution sources into several categories, divide the area to be const...

Embodiment 3

[0143] The method described in Embodiment 1 provided in this specification can realize business logic through a computer program and record it on a storage medium, and the storage medium can be read and executed by a computer, so as to achieve the effect of the solution described in Embodiment 1 of this specification. Therefore, the present invention also provides a computer-readable storage medium for building a map of atmospheric pollution sources, including a memory for storing processor-executable instructions, and when the instructions are executed by the processor, the methods for building a map of atmospheric pollution sources described in Embodiment 1 are implemented. A step of.

[0144] The storage medium may include a physical device for storing information, usually after digitizing the information and then storing it in a medium using electrical, magnetic or optical means. The storage medium may include: devices that use electrical energy to store information, such ...

Abstract

The invention discloses an atmospheric pollution source map construction method and device, a storage medium and electronic equipment, and belongs to the field of atmospheric monitoring. According to the method, mutual verification and supplement among databases are carried out in combination with pollution source data of multiple sources, mutual evidence is carried out according to pollution source positions, spatial aggregation degrees, atmospheric pollutant emission and the like in the pollution source data, and a pollution source credibility evaluation system is established; according to the pollutant concentration inversion result, the pollution source with high reliability is reserved, and the pollution source with low reliability is filtered out; dividing the reserved pollution sources into a plurality of classes, performing grid division on the to-be-constructed region according to a certain size, and performing analysis to obtain information of various pollution sources of each grid; in each grid, the color of the grid is rendered according to the influence of various pollution sources on the pollutant concentration, and an atmospheric pollution source map is obtained. According to the invention, a set of refined atmospheric pollution source atlas with data fusion is established, and a basis is provided for scientization and precision of atmospheric pollution management.

Description

technical field [0001] The invention relates to the field of atmospheric monitoring, in particular to a method, device, storage medium and electronic equipment for constructing a map of atmospheric pollution sources. Background technique [0002] Air pollution refers to the phenomenon that the concentration of pollutants in the atmosphere reaches a harmful level, which damages the ecosystem and the conditions for the normal survival and development of human beings, and causes harm to people and things. Its causes include natural factors (such as volcanic eruptions, forest disasters, rock weathering, etc.) and human factors (such as industrial waste gas, fuel, automobile exhaust and nuclear explosions, etc.). The impact of air pollution on the human body is first to feel uncomfortable, and then to a reversible physiological reaction, and then to the emergence of acute hazard symptoms. [0003] Air pollution has serious harm to industrial and agricultural production, which ca...
