Thronging
to Dig Gold and Aweto Sacks the West Qinghai Plateau
Beijing
Evening Newspaper, May 20, 2000: Recently, along the Qinghai-Tibet and
Qinghai-Kangding roads, one after another, trucks fully with full-load
of local people, bound in haste from the east agricultural zone in Qinghai
Province toward the west Qinghai Plateau, especially the upper Yellow and
Yangtze Rivers. These people take along digging tools such as shovels
and picks, and living necessities as bed linen and tents. Most of them
are to dig gold, and some go there for aweto. Many zoologists and environmentalists
are deeply worrying about the situation. They appeal the government to
forbid collecting gold and aweto in the region for a long-term and restore
grasses by closing the region off, like the ways of restoring forests.
Seven Sand-storms in China This Year
Since this spring, seven large-scale sand-storms
came forth in the north China successively. Its frequency, intensity and
scope are unusual in history record. In the cities invaded by sand-storm,
the sky was so turbid that the visibility was quite low. For instance,
when the fifth sand-storm stroke Beijing, the peak value of sand density
monitored by the Beijing Environmental Protection Center in the Ding Mausoleum
was more than 1000 mg/m3. This not only affected the local traffic, but
also brought many inconvenience to people’s living. The flying sands made
the outdoor people feel dyspnoea and eye-ache.
Northwest China is the region where the
sand-storm mostly occurs. Since the nineties, the average occurrence frequency
is once per year. Recently its frequency climbs year by year. Sand-storm
has already happened seven times this year. Its scope expands from Beijing
to Yangtze drainage area, even Shanghai and Nanjing were so affected that
the air quality is very bad and “mud rain” took place. Experts in the
Center of Desertification Control, State Forestry Administration, deem
that the frequently occurring of sand-storm is due to climate change, as
well as the destroy of vegetation and desertification.

200,000
km2 Offing Sea Suffered Pollution
XINHUA
Agency Report in May: A three-year survey conducted by the State Oceanic
Agency indicates that there are already 200,000 km2 offing seawater has
been polluted in China. The water quality in the area is under the standard
National Grade 1, which has negative impact on the water quality of sea-fishery
areas.
In
the 200,000 km2 area, the water quality of 40,000 km2 is even lower than
the standard National Grade 4 and thus is not able to meet requirement
of aquaculture, sea-bathing, on-sea sports and entertainments, as well
as coastal tourism zone, seaport and ocean development zone.
In
most off-shore region, the sea area where the water quality is under the
standard Grade 1 has expanded to 10?30 km away from the seacoast, while
it has already reached to 120-200 km off shore in Jiangsu, Shanghai, Zhejiang
and Liaodong Gulf.
The
main factors which have obviously spoiled China’s seawater are nutrition
like nitrogen and phosphorus, oil, organic substances and heavy metals
such as plumbum, hydrargyrum and etc.
The
Frequency of Offing Red-tide Increasing
XINHUA
Agency Report in May: It is reported in a recent statistics of the
State Oceanic Administration that due to the aggravating pollution of nutrition
salt and organic compounds year by year, the frequency of offing red-tide
in China is increasing. There are more than 200 times of red-tide in total
during last ten years, with an average of 20 per year.
Red-tide
often occurs in offing in Guangdong, Shandong, Zhejiang, Liaoning and Shanghai.
The most frequent areas are estuaries of Yangtze and Zhujiang, Liaodong
Gulf, Hangzhou Gulf, Laizhou Gulf, Daya Gulf, Shantou-Shanwei sea area
and Tianjin offing.
During
the three years from 1997 to 1999, 45 times of large-scale red-tides were
recorded. Among them, 24 occurred in Bohai and Huanghai, and 14 in Nanhai.
They resulted in a total loss of over RMB 2 billion.
Experts
have indicated that in recent years, the occurring area of red-tide is
expanding, and its duration is longer and longer while its damage is getting
worse. Now, red-tide not only occurs in summer, but also in spring
and winter; not only in the offing, but also trends to the open sea. Moreover,
it is discovered that there are new life-forms causing red-tide.
