Embodiment Construction
[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. The various examples are provided by way of explanation of the invention and do not limit the invention.
[0038]Urban agglomerations are the country's leading innovation centers, such as the Beijing-Tianjin-Hebei urban agglomeration (replaced by BTH below), the Yangtze River Delta urban agglomeration (replaced by YRD below) and the Pearl River Delta urban agglomeration (replaced by PRD below). BTH is located in northern China, including eight cities in Beijing, Tianjin and Hebei Province. YRD is a large and highly competitive urban agglomeration located in eastern China, including Shanghai and 15 cities in Zhejiang and Jiangsu provinces. PRD is the most competitive and dynamic urban agglomeration in the Asia-Pacific region, located in southern China, including 9 cities in Guangdong Province. To better study the health hazards of...

Abstract
The invention belongs to the technical field of pollution prevention and control, and discloses an analysis method and an analysis device for PM2.5 pollution of urban agglomeration. The analysis method comprises the following steps: determining urban areas and suburban areas in an urban agglomeration according to population density and population total number; according to the PM2.5 concentration and the exposed crowd, the PM2.5 exposure risk of the urban area and the PM2.5 exposure risk of the suburban area are calculated respectively; and according to the PM2.5 concentration and the PM2.5 exposure risk of the urban area and the PM2.5 concentration and the PM2.5 exposure risk of the suburban area, analyzing the PM2.5 pollution condition of the urban agglomeration. The analysis device comprises a determination module, a first calculation module and a first analysis module. According to the technical scheme, the difference of PM2.5 in the urban area and the suburban area, different effects of air cleaning policies, the correlation between the change of PM2.5 and the population and the area of the area and the difference of exposure risks caused by PM2.5 are analyzed, and the influence of human activities on atmospheric pollution is better clarified.
Description
technical field [0001] The invention belongs to the technical field of pollution prevention and control, and particularly relates to an analysis method and an analysis device for PM2.5 pollution in urban agglomerations. Background technique [0002] Air pollution is a major environmental risk factor in the world, with approximately 7 million deaths worldwide each year. Among air pollutants, PM2.5, or particles smaller than 2.5 microns in diameter, are considered the most harmful to human health. Numerous studies using epidemiological cohorts have also highlighted that long-term exposure to PM2.5 can have severe human health effects and lead to respiratory or cardiovascular disease. In China, PM2.5 has been an important public health issue for the past few decades, ranking fifth among risk factors for disease burden. In order to improve air pollution, a number of clean air policies and standards have been formulated, such as national ambient air quality standards, air pollu...
