Abstract

The embodiment of the invention provides a regional air pollutant concentration prediction method, terminal and computer readable storage medium. The method includes using a calculated daily average historical pollutant concentration data set and a preprocessed daily historical meteorological data set as sample data sets, utilizing a random forest model to perform training, wherein the random forest model includes a plurality of decision trees, each decision tree being implemented by use of a multilayer feedforwad neural network; determining predicted meteorological data of a preset number ofdays in the future predicted on the same day at current time; preprocessing the predicted meteorological data; and according to the preprocessed predicted meteorological data and pollutant concentration data monitored on the same day at current time, utilizing the trained random forest model to predict pollutant concentration data of the preset number of days in the future of a region to be predicted. The regional air pollutant concentration prediction method provided by the embodiment of the invention improves regional air pollutant concentration prediction precision, and has relatively a high generalization capability.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for predicting the concentration of regional air pollutants, a terminal and a computer-readable storage medium. Background technique [0002] In recent years, large-scale air pollution incidents have frequently occurred in most parts of my country, and the air pollution problem has seriously affected the normal life and production of the people. Common air pollutants, such as PM2.5, PM10, O3, etc., are extremely harmful to human health. Use reliable and easy-to-use air forecasting methods to predict the occurrence and change trend of air pollution, so that government departments can keep abreast of future air quality conditions, and take early response measures in the face of heavy air pollution events to ensure people's lives and health, with the minimum economic cost It is particularly important to realize the maximum social benefits at a low cost. [0003] A...
