Embodiment Construction

[0044] The present invention provides a method for measuring the discharge of coal-fired air pollutants in a one-story house. The following will take the coal-fired discharge in the plain area of ​​Beijing from August to October 2013 as an example to describe in detail. The method includes the following steps:

[0045] 1) Satellite data processing and remote sensing extraction of bungalow information: Obtain satellite images taken by the Quick-Bird satellite in the plain area of ​​Beijing from August to October 2013, and preprocess and enhance the satellite images, that is, by 1: The 50,000-scale topographic map is used as the reference to carry out geographic coordinate registration on the satellite image, select several control points on the satellite image or topographic map, and use the polynomial method to perform image correction on the satellite image; after preprocessing and image enhancement, the multispectral image Fusion with panchromatic images to generate satellite...

Abstract

The invention relates to a method for measuring the air pollutant emission amount of coal burned at bungalows. The method includes the following steps that satellite data are processed, residential bungalow information is extracted in a remote sensing mode, the area of residential bungalows is refined, and the amount of the coal burned at the bungalows, pollutant emission factors of the coal burned at the bungalows and the pollutant emission amount of the burned coal are calculated. The method has the advantages that the ground monitoring and satellite remote sensing technology is used fully to obtain the area and space distribution of the bungalows at an area to be measured, on the basis, calculation is conducted on the amount of the coal burned at the bungalows and the emission amount of main pollutants, and the method is beneficial exploration and innovation of air pollution surface source remote sensing monitoring operation and provides a scientific basis for air pollution reduction.

Description

technical field [0001] The invention belongs to the field of atmospheric environment monitoring, and in particular relates to a method for measuring the emission of air pollutants from coal-fired bungalows. Background technique [0002] The primary air pollutant in Beijing is particulate matter, and one of the main sources of pollutants is coal-burning emissions. The adjustment of energy structure is the top priority of Beijing's air pollution control work. The "Beijing 2013-2017 Clean Air Action Plan" has as many as 20 measures related to coal combustion in the division of tasks within the bureau. Among them, civilian coal is generally burned directly. Due to the limitation of combustion and dust removal technology, the emission of particulate matter is very large. However, due to the unstable combustion situation, the uncertainty of emission is also large, so the emission factor is important for the accuracy of emission source inventory. The use of emission factors that c...
