Gridding arrangement method of air pollutant monitoring stations

Abstract

The invention provides a gridding arrangement method of air pollutant monitoring stations. The method comprises the following three steps: step 1, coarse grid layout, specifically, a hot spot region is encrypted on the basis of uniformly distributed grids according to investigation conditions of local population and industry distribution, pollution occurrence frequency and pollution influence range; step 2, the grid adaptation degree of the hot spot area is improved, the actual effective monitoring range of a monitoring station is reversely solved based on an adjoint probability method according to local meteorological conditions, and data reference is provided for the size of a fine grid; and step 3, grid optimization is conducted, an optimization analysis technology is utilized to solvethe gridding distribution density and the grid length-width ratio according to the obtained effective monitoring range of the monitoring station, and full coverage of the monitoring area is realized.According to the method, the arrangement scheme of the monitoring grids can be efficiently and accurately provided according to the actual situation, the method has guiding significance for position selection of monitoring stations and evaluation of the monitoring effect of existing stations, and treatment and improvement of urban air are facilitated.

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...
