She said the district will add more than 22 hectares of green area this year and some new tree species will be planted in parks.

"There is an urgent need to build up a green belt in the city," she added.

Tong Lizhi, a member of the capital's political advisory body, called for the new leadership to establish a pollution warning system.

"Under the system, a risk evaluation should be conducted in advance, including daily ones and long-term ones," he added.

Some said the government should also look into the traffic issue when it deals with air pollution, because car emissions are a major source of air pollution.

An Jianjun, a political adviser, said dust from farmland and emissions from agricultural vehicles can also cause pollution, "so how to deal with them is important", he said.

Zhou Mudi, a resident who returned to Beijing from Britain last year, said she was glad to see the new leadership has attached importance to the environment and public transport.

"Car emissions are one of greatest contributors to air pollution, which is hard to avoid," she said. "The current public transport system in Beijing is still inconvenient compared with Britain, while the city's planning and construction in the districts seem disordered."

Xia Yuchen, a 25-year-old resident who returned to Beijing from France three months ago, welcomed the new leadership's determination, but said she hoped the problems can be tackled as soon as possible.

"To tackle air pollution, a transparent supervision system is needed," she said. "In Western countries, governments must disclose the pollution data in a timely matter, but our government isn't good at taking emergency action."

"I'm still looking forward to the new leadership's real action to solve the congestion and pollution this year," she added.
