Embodiment Construction

[0027] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0028] An air pollution event is defined as the continuous independent space occupied by climate phenomena that meet air pollution standards in both spatial and temporal dimensions, as well as the totality of process semantics that evolve in this time and space. The spatial distribution of air pollution in a region at a certain moment is a collection of snapshots of multiple air pollution events in the region. According to the knowledge of actual observation and meteorology, the range of influence of the same air pollution event in space is continuous, and wh...

Abstract

The invention discloses a process-oriented air pollution event modeling method. The method comprises the steps of firstly, defining an air pollution event and identifying snapshots of the air pollution event at all moments according to air pollution standards; and then performing modeling on the air pollution event from a process perspective according to a spatial relationship of the same air pollution event snapshots in a continuous time sequence, thereby obtaining an air pollution process-based model. According to the modeling method provided by the invention, time and spatial information of all stages of the air pollution event can be intuitively obtained; association of air pollution events with the surrounding geographic environment and special events can be assistantly comprehended; and guidance is provided for exploring causes for the air pollution event and policies.

Description

technical field [0001] The invention belongs to the technical field of geographic information systems, and in particular relates to a process-oriented air pollution event modeling method. Background technique [0002] my country's rapid urbanization process is accompanied by many "urban diseases". Among them, air pollution represented by PM2.5 will cause serious damage to the health of urban residents, and has received great public concern. Regarding the current situation of urban air pollution, on the one hand, the public urgently needs to know the real-time air quality of the surrounding environment in order to take effective measures to reduce the harm caused by air pollution; on the other hand, for urban managers, in response to public needs Based on this, it is expected to have a deeper understanding and understanding of the internal mechanism of the causes of air pollution and the development process, so as to provide theoretical support for decision-making in fundame...
