Since PM2.
Conversely, the lower the PM2.
The research team of Tsinghua University recently published a related study in "Nature·Earth Science", quantifying the main factors affecting China's PM2.
This study is the first quantitative analysis of the factors affecting long-term changes in China's atmospheric PM2.
If PM2.
"PM2.
Zhang Qiang’s research team designed a set of multidisciplinary model methods such as atmospheric sciences, environmental sciences, and economics, which coupled emission inventories, air quality, and health effects, and quantitatively decomposed the economic growth and the end of pollution from 2002 to 2017.
By reproducing and analyzing the real world in the model, if we look at the impact of economic development factors alone, the team found that economic development has led to an increase in fossil energy consumption and increased PM2.
In other words, if the PM2.
"Ten Atmosphere" shot, the turning point appeared
"We have clearly seen a turning point after the implementation of the Ten Atmosphere
How much do you benefit? The study found that the implementation of the pollution end treatment policy has a huge effect.
In 2013, the State Council issued the "Air Pollution Prevention and Control Action Plan", which is the "Atmospheric Ten Measures".
"For example, between 2002 and 2017, China's coal consumption as a proportion of primary energy consumption dropped from 68.
Aging makes PM2.
The study found that factors such as the increasing degree of aging in China and the increase in the total population increased the risk of PM2.
"In the future, more stringent clean air measures are needed
"It is expected that in the future air pollution improvement, the role of structural adjustment factors such as energy structure adjustment and economic structure optimization will become more prominent
.
" Zhang Qiang said that "subtraction through optimization" will become the focus of the "14th Five-Year Plan" period.
Various industries should accelerate the transition from “end treatment” to “source treatment”, release the pollution reduction potential of energy, industry, transportation, and land use structure adjustment, and accelerate the transition to clean and low-carbon energy in order to protect the public health of the population
.
