Years of statistical analysis show that about 80 percent of the
dust causing Beijing’s dusty weather comes from beyond the national
border, Ren Zhenhai, an academician with the Chinese Environmental
Science Academy said here Monday.
Ren made the remark while delivering a report to the Environment
and Resources Protection Committee of the National People’s
Congress (NPC).
Mongolia is one of the main sources of the dusty weather in most
regions of north China, especially of Beijing. Ren and five other
experts also made reports on air quality, water pollution,
environmental protection of the west and the environmental goals
and measures of the country’s 10th Five-Year Plan.
Ren pointed out that the foreign dust sources that bring about
dusty weather in the Xinjiang Uygur Autonomous Region mainly lie in
the deserts of Kazakhstan and Russia.
Since Beijing is now developing very fast, some of the dusty
weather in Beijing is due to the vast number of construction sites
and large amount of bare land, he said.
Ren concluded that several elements cause dusty weather in Beijing,
namely, the overall climate, deterioration of the environmental
system in the locality and neighboring regions, local construction
sites and bare land.
