Sandstorms not to dull Beijing's 'Green Olympics'
[ 2006-04-24 10:46 ]
盡管最近在北京頻繁出現(xiàn)了強浮塵天氣，中國政府有關(guān)部門仍對北京2008綠色奧運的目標保持樂觀。國家林業(yè)局沙塵暴災(zāi)害應(yīng)急處置辦公室的負責(zé)人指出，中國將繼續(xù)造林工程，建設(shè)防沙治沙項目，確保為北京2008提供一個良好環(huán)境。目前，侵擾北京的沙塵暴主要來自北方幾個省份和中國境外，而北京市內(nèi)的主要沙塵來源是郊縣的沙質(zhì)土地和市內(nèi)的建筑工地。
Despite the frequent sandstorms that have hit Beijing this spring, the
Chinese government is still optimistic that the 2008 Olympic Games in Beijing
will be "Green Olympics".
"China will intensify afforestation efforts in and around Beijing to
create a better environment for the Olympic Games," said Liu Tuo, head of the
desertification prevention and
treatment department under the State Forestry Administration (SFA) on
Thursday.
Liu said China launched an afforestation project in sand-prone areas in Hebei and Shanxi provinces and
the Inner Mongolia Autonomous Region in 2001 to tackle sandstorms that had been
plaguing Beijing's environment for years.
The coverage of forests and grass in these areas increased by an average 30
percent, said Liu.
The sand control project has improved the air quality in Beijing. The
monitoring network of the Beijing Environmental Protection Bureau found a
significant drop in major pollutants in the city in 2005, and more than 230 days
of the year had good weather, compared with 100 days in 1998.
"It's high time for the forests and grasslands to play their roles in the
2008 Olympic Games. What's more, the Olympic Games is scheduled in August, when
sandstorms seldom happen in Beijing," said Liu.
Ten sandstorms have stricken northern China since February this year and
Beijing, which neighbors the Inner Mongolia Autonomous Region, a major sand
source in China, has suffered the most serious spring air pollution since
2002.
The strong sandstorm on Sunday alone brought more than 10 tons of sand and
dust per square kilometer to the urban area of Beijing, according to the SFA's
statistics.
Fifty to sixty percent of the sandstorms which hit Beijing originate from
places outside Beijing and even outside China, and the major sand sources in
Beijing are the sandy areas in its outskirts and the construction sites in the
city, said Yang Weixi, chief engineer of Liu's department.
Higher temperatures and less rainfall in the arid parts of North China,
together with frequent cold air flow from Siberia, were to blame for more severe
sandstorms, according to Yang.
The drought sucks moisture from the soil and makes sand easier to be picked
up by the wind, said Yang.
The Beijing municipal government has invested heavily to improve its
environment since it won the right to host the 2008 Olympics. It spent 60
billion yuan (7.5 billion U.S. dollars) on pollution control projects from 2000
to 2005.
"The sandy area in Beijing has thus dropped to 67,000 hectares from 200,000
hectares three years ago, effectively reducing the sand source inside Beijing,"
said Yang.
It is a long-term and tough task for desertification prevention and treatment
in China as there are around 1.74 million square kilometers of desertified land
in the country, accounting for 18 percent of China's land area, said Liu.
China would strengthen international cooperation in this field and take
measures against overgrazing,
over-logging and over collection of
fire wood in the desertified area to honor the promise that all the country's
desertified land can be repaired by 2050, said Liu.
