“ A growing variety of airport areas are planned
specifically to encourage these connections, making a type of metropolitan growth referred to as "aerotropolis".
On the one hand, suburbanization implies that a better share of the metropolitan inhabitants lives in peripheral sites, potentially with higher accessibility to airports.
The flows of passengers and cargo generate significant wealth, but airports also have attracted
economic actions that want the accessibility - more
and more at the worldwide scale - that airports make potential.
Thus, airports are sited on the periphery of urban areas because such sites supply a steadiness between available land prices and accessibility to the city core.
Hilly land may be flattened, and swampy landfilled, of course,
however at a price. In different circumstances,
similar to Dun Huang in China, specific geographical constraints had to
be revered, particularly that the airport could not eat scarce agricultural land.
China’s greater success in limiting the spread
of the disease helped propel Chinese airports up in the
world league tables; in 2020, seven of the world’s ten busiest airports ranked by passenger
volumes had been in China, led by Guangzhou Baiyun International Airport. ”
