Beijing plans ventilation corridors

BEIJING: Beijing is planning to build a web of ventilation corridors to facilitate air flow and blow away smog and pollutants, municipal authorities said.

The five primary ventilation corridors are designed to be more than 500m-wide.

Some secondary corridors will be over 80m-wide, said Wang Fei, deputy head of Beijing’s urban planning committee.

The corridors will be created by connecting the city’s parks, rivers, lakes and highways along with their green belts, as well as low building blocks.

The five major ventilation corridors largely run from the northern suburban areas to the south.

One corridor will run through the central axis of Beijing from Taiping Suburban Park in the north, via the Olympic Park, the Temple of Heaven, all the way to the Beijing-Shanghai Highway in the southern end of the city.

In addition to the planned primary and secondary ventilation corridors, other smaller corridors will also be added to the system. Construction in these zones will be strictly controlled, and obstacles along the way will be gradually removed, Wang said.

Some Chinese cities, such as Shanghai and Fuzhou, have been building ventilation corridors to combat air pollution.

“Ventilation corridors can blow away heat and pollutants, relieving the urban heat island effect and air pollution,” Wang added.

Air pollution has become a major concern of residents in Beijing as the city saw the heaviest smogs of years in November and December 2015, partly due to winter heating. — China Daily/Asia News Network
