Embodiment 1

[0051] The characteristic air pollutants and historical air quality levels of this embodiment are obtained with the city as the regional scope and the four seasons as the time range.

[0052] The historical air quality level in this embodiment is specifically a collection of air quality levels in Guangzhou in the previous year (2019), obtained through the public network https: / / www.aqistudy.cn / historydata / .

[0053] A kind of air quality evaluation model such as formula (1);

[0054]

[0055] Among them, c i is the standard air quality level, l i is the fuzzy comprehensive evaluation factor, i is a natural number greater than zero, and ClassLevel represents the air quality level;

[0056] Among them, air pollutants include the six main air pollutants PM pointed out in the "Ambient Air Quality Standards" 2.5 , PM 10 , SO 2 , NO 2 , CO and O 3 The concentration limits of each pollutant with regard to different air quality grades refer to "Ambient Air Quality Standard" ...

Embodiment 2

[0095] The historical air quality level obtained in this embodiment is the same as in Embodiment 1.

[0096] A method for building an air quality evaluation model, comprising the following steps:

[0097] S1, using the Pearson correlation coefficient as an index to obtain the correlation degree, obtain the correlation degree between the concentration sequence of air pollutants and the historical air quality level, and select the air pollutant corresponding to the correlation degree > 0.5 as the characteristic air pollutant;

[0098] obtaining a first set of evaluation factors, a second set of evaluation factors, a third set of evaluation factors and a fourth set of evaluation factors;

[0099] Wherein, the first evaluation factor set corresponds to winter, the second evaluation factor set corresponds to spring, the third evaluation factor set corresponds to summer, and the fourth evaluation factor set corresponds to autumn;

[0100] Guangzhou's first evaluation factor set = {PM...

Embodiment 3

[0157] A method for evaluating air quality, comprising the steps of:

[0158] S61, obtaining characteristic air pollutants, concentration values ​​of characteristic air pollutants and historical air quality levels, and obtaining a sample set;

[0159] S62, input the sample set obtained in S61 into the air quality evaluation model, and obtain the air quality grade evaluation result;

[0160] Specifically, the air quality evaluation model is the air quality evaluation model disclosed in Embodiment 1, or the air quality evaluation model constructed by the air quality evaluation model construction method disclosed in Embodiment 2.

Abstract

The invention discloses an air quality evaluation model, a model construction method and an application thereof. A final evaluation result is determined by adopting a weighted membership degree principle, seasonal differences are considered at the same time to dynamically analyze changing conditions of characteristic atmospheric pollutants, a more powerful support is provided for making decisionsof air pollution problem treatment measures in time, and the objectivity of an evaluation result is more powerfully ensured; meanwhile, the change condition of the characteristic atmospheric pollutants can be dynamically analyzed as time goes on, and more powerful support is provided for making decisions on air pollution problem treatment measures in time.

Description

technical field [0001] The invention relates to the technical field of air quality comprehensive evaluation, in particular to an air quality evaluation model, a model construction method and an application thereof. Background technique [0002] As a major environmental pollution problem, air pollution has attracted great attention in our country. Being in a highly polluted atmospheric environment for a long time will cause serious harm to human health. The negative impact of air pollution not only harms human health, but also hinders economic development. Therefore, it is critical to provide valuable information for atmospheric protection decision-making. Air quality assessment plays a vital role in interpreting air quality and early warning to protect human health from the impact of heavily polluted atmosphere in daily activities. [0003] The existing air quality evaluation methods usually use the six main air pollutants (PM) pointed out in the "Ambient Air Quality Stan...
