How has Urbanisation in China affected the environment?
Cities in China are among the most air polluted cities in the world, which has resulted from the rapid urbanization accompanied by increasing industrial development, energy consumption and urban traffic.
How does urbanization cause pollution?
The danger of urbanization is that factories emit a lot of pollution. They emit smoke into the atmosphere, pollute the water/land around them and create a lot of noise with their machinery. As a result of urbanization, there is a lot of waste materials and it is very detrimental to the environment.
What is the main cause of urban air pollution in China?
Energy consumption, especially coal consumption, is the main source of anthropogenic air pollution emissions in Chinese cities.
What are the problems of urbanization in China?

What causes China’s pollution?
The causes of Beijing’s widespread air pollution can be attributed to a number of factors: an enormous economic boom, a surge in the number of motorized vehicles, population growth, output from manufacturing, and natural reasons which include the city’s surrounding topography and seasonal weather.
What is the biggest source of pollution in China?
coal
China consumes almost as much coal annually as all other countries combined, and coal burning in the country is the biggest source of both air pollution and greenhouse gas emissions, the leading cause of climate change.
How polluted is the air in China?
Beijing’s peak average daily AQI in 2020 reached 262, which the EPA considers very unhealthy. High levels of air pollution take a major toll on public health. A study by the Health Effects Institute found that unhealthy levels of PM2. 5 led to roughly 1.42 million premature deaths in China in 2019.
What are the economic impacts of urbanisation in China?
Urban growth results from both rural-urban migration and natural increase from births in the cities exceeding deaths. Urbanisation is part of economic development which is rapidly increasing in China. This results in rising per capita incomes and demand for non-agricultural goods.
What are the causes of air pollution in China?
Economic growth and rapid urbanization in China have caused a tremendous increase in the consumption of energy and emissions of SO 2, NO x (Hao et al., 2002), volatile organic compounds (VOCs) (Shao et al., 2000), TSP, and other pollutants.
Does urbanization affect the shape of Environmental Quality in China?
The results showed that PM2.5 pollution generally presented a worsening situation in most provinces during the study period. PM 2.5 -urbanization relationship approved an inverted U-shape EKC pattern in whole China and the central and eastern region, but presented an N-shape EKC pattern in the developed eastern region.
What is the relationship between urbanization and pollution?
The environmental pollution caused by urbanization is mainly due to the effects, such as the increase of urban land use, of the excessive concentration of population [[29], [30], [31] ]. The destruction of the environment through economic growth is mainly due to excessive consumption of energy.
Why is pm 10 the most common pollutant in Chinese cities?
For the past three years, PM 10 has been the predominant pollutant in most Chinese cities. Economic growth and rapid urbanization in China have caused a tremendous increase in the consumption of energy and emissions of SO 2, NO x (Hao et al., 2002), volatile organic compounds (VOCs) (Shao et al., 2000), TSP, and other pollutants.
