A grid arrangement method for air pollutant monitoring stations

Abstract

The invention proposes a method for grid arrangement of air pollutant monitoring stations. The method includes three steps: the first step is coarse grid layout, according to the investigation of the distribution of local population and industry, the frequency of pollution, and the scope of pollution influence, the hotspot area is encrypted on the basis of a uniform grid ; The second step is to improve the grid fitness of the hotspot area. According to the local meteorological conditions, the actual effective monitoring range of the monitoring station is reversely obtained based on the adjoint probability method, which provides data reference for the size of the fine grid; the third step is the network In the grid optimization step, according to the effective monitoring range of the monitoring station, the optimization analysis technology is used to solve the grid distribution density and grid aspect ratio, so as to realize the full coverage of the monitoring area. The present invention can efficiently and accurately propose the arrangement plan of the monitoring grid according to the actual situation, has guiding significance for the position selection of the monitoring site and the monitoring effect evaluation of the existing site, and is helpful for the management and improvement of urban air.

Description

technical field [0001] The invention belongs to the technical field of atmospheric environment monitoring and risk early warning, and in particular relates to a method for grid arrangement of air pollutant monitoring stations. Background technique [0002] Air pollution has become a serious problem faced by modern cities. The unreasonable discharge of pollutants not only affects the environment, but also threatens the health of residents. As the most direct means of atmospheric environmental monitoring, the atmospheric environment monitoring network composed of air pollution monitoring stations can obtain real environmental pollution data and reveal the distribution of air pollutants in time and space. Its existence is important for the control and management of urban air pollution sources. As well as improving urban air quality is of great significance. The grid arrangement scheme of pollutant monitoring stations is a very important technical indicator, which is related to...
