Beijing is planting trees and plants along riverbanks instead of covering them with concrete to fix its river system. It has taken almost 10 years for the capital to accept and use this idea. The ecosystems in the streams are gradually coming back to life because of the cleaner water, providing a good habitat for animals and plants, and ideal leisure sites for local residents.  Zhuanhe which connects with Kun Ming Lake in the Summer Palace is one of successful example of the river ecological treatment in Beijing. "In Beijing, there are 52 rivers with a total length of 520 kilometers inside the sixth ring road. Yongding and Jingmi rivers are the city's two main water sources, and Qinghe, Bahe, Tonghui and Liangshui are key drainage waterways," said Yu Kongjian, dean of the Sight Engineer Institute with Peking University. Originally, Beijing only wanted to control the floods by letting water flow out as soon as possible. Therefore, riverbanks were cemented down in order to prevent water leakage and the growth of plants, which could slow the water speed down. However, the shortage of rainfall in Beijing since 1999 showed that this method was not correct. On the one hand, streams had less fresh water to clean themselves. On the other, more polluted water was dumped into the rivers as more people moved into the capital. And in the summer of 2001, something bad happened. "The rivers in Beijing turned blue overnight and gave off a smelly odor," said Liu Peibin, vice engineer of Beijing Water Authority. There was an algae bloom due to so much pollution in the water. Algae covered the water surface and consumed most of the oxygen, and many creatures in the water died as a result. These "concrete pools" became the haven for swarms of mosquitoes which forced tens of thousands of residents nearby to close their windows and doors tightly especially in summer days. The water authorities had to act quickly for public safety. The first step was to demolish the concrete covering the riverbanks. The soil was exposed to water again, and the water could circulate down to the riverbank. Secondly, in order to stimulate oxygen in the streams, engineers put big stones in the water to create mini waterfalls. And they grew trees like willows and plants such as bulrush along the riverbanks. "Bulrush can purify polluted water through absorbing nitrogen and phosphorus in the water and exhaling oxygen," Deng added. "Gradually Zhuanhe came back to life and got rid of the polluted and smelly water. This would be impossible today if the brook was still covered in concrete." "What we did with Zhuanhe is a milestone in the progress of river treatment with new ecological ideas," said Deng Zhuozhi, vice engineer of Beijing Water Project Institute. He took charge of the Zhuanhe project. "How to fix up rivers depends on our attitude towards floods. We should learn to make friends with floods in a country where two-thirds of China's cities are short of water. Therefore we should reserve water as much as possible instead of discharging it ineffectively," said Yu.

Shanghai - The Shanghai World Financial Center, the highest building on the mainland, was topped out on Friday.The Shanghai World Financial Center on the way up, at different stages of construction. The 101-story building, the highest on the mainland, was topped out on Friday. Niu Yixin"The 101-floor office tower is expected to be completely finished in the spring of 2008," said Sun Wenjie, general manager of China State Construction Engineering Corp.The Shanghai skyscraper is located in the prime Lujiazui zone in Pudong on a 30,000-sq-m site.With an overall construction area of 381,600sqm, the Shanghai World Financial Center will be one of the tallest buildings in the world at 492 meters. That's 70 meters higher than Jinmao Tower, formerly the highest on the Chinese mainland.Japan's Mori Building Co and 40 other foreign companies will invest a total of 8 billion yuan in the development."As the economy warms up, we are more confident about Shanghai and the whole of China," said Hiroo Mori, president of the Shanghai World Financial Center Co, a subsidiary of Mori Building Co Ltd.The building is expected to become home to high-profile international businesses, department stores, art galleries, clubs and a five-star hotel."As China's economy roars ahead, more capital and businesses are expected to flow into the country, especially to Shanghai. The city aims to become a world center for trade and finance - with Lujiazui as its showpiece," said Mori.Lujiazui will have three tall buildings, one of which is the completed Jinmao Tower, each rising above 400 meters. The buildings were planned by local government after an international design competition in the early 1990s.The Shanghai World Financial Center will be the "mountain peak" of the city's skyline, with neighboring buildings descending in height on either side.Mori said the design and technology used in the construction of the building should allay any safety fears.Beams will be used to connect the outer supports and the internal elevator area instead of bolts, as were used in the World Trade Center in New York City."We will use welding to fasten the frame and the triangular construction will enhance its stability," Mori said.Construction of the building began in 1997, but was stopped shortly after because of financial problems brought about by the Asian financial crisis. Building work resumed in 2003.

BEIJING - The Chinese Academy of Social Sciences (CASS), the country's top think tank, published its eighth annual report on Monday and introduced a new international strategy.The report - "China's Modernization 2008" - proposed a brand new concept, the so-called "Peace Dove Strategy".The strategy, with the principle of "Follow the UN Charter and Promote World Peace", calls for the building of a favorable international environment for China's modernization.The "Peace Dove Strategy" makes the United Nations the head of the Dove.Asian nations are the foreside; the Asia-Pacific Economic Cooperation is the eastern wing, and the proposed "Asia-Europe Economic Cooperation", which is upgraded from the existing Asia-Europe Meeting, is the western wing.South America, Oceania and Africa bring up the rear.The strategy, which centers on Asia and faces the world, calls for cooperation of all member nations on an equal, mutually beneficial basis.Under the strategy, China will optimize the structure of its international modernization strategy, increase its national capacity in international modernization, and improve the international environment for the country, according to He Chuanqi, head of the CASS Center on the Study of China's Modernization.The strategy was created drawing upon international experience of the past 300 years and the history and realities of China's international modernization, the official said.The report has been published and distributed as a single volume by the Beijing University Publishing House.

Wuhan -- China's first bank-invested trust company is officially set up in Wuhan, capital of central China's Hubei Province, on Sunday.The new trust company is held by the Bank of Communications (BOCOM), China's fifth largest lender, and Hubei provincial finance department, which control 85 percent and 15 percent of the total shares respectively.The BOCOM invested 1.2 billion yuan (about US0m) to buy the shares of the Hubei international trust and investment company, the first commercial bank investment in a trust company approved by the China Banking Regulatory Commission.Jin Dajian, chairman of the new company named "jiaoyin-guoxin", or BOCOM-International Trust, said the company would focus on "professional wealth management".Jin called the establishment of the new trust company "a breakthrough for China's trust industry", given that the country's law on commercial banks, effective since 1995, did not allow commercial banks to make trust investment.The regulation was not lifted until the end of last year, when the China Banking Regulatory Commission encouraged financial institutions, including commercial banks, to acquire trust companies.The BOCOM, a large state-owned commercial bank, was established in 1908, and the Hubei international trust investment company was founded as a non-banking financial institution under Hubei provincial government in 1981.

XI'AN -- A fire burnt up trees and shrubs on a mountain that shrouds one of the most famed imperial mausoleums in the ancient city of Xi'an in northwest China's Shaanxi Province, but no damage was caused to the cultural relics, local museum officials said on Sunday.The fire broke out around 2:00 p.m. Saturday on the western part of a mountain that encased the tombs of a powerful Chinese empress Wu Zetian and her husband Gaozong in the Tang Dynasty (618-907). The Qianling Mausoleum, as the tombs are called, reportedly houses the most precious possessions of the two rulers, including paintings, ceramics, calligraphy works and jewelry articles.The fire was fanned up by sandstorms which struck the area on Saturday, said Fan Yingfeng, curator of the Qianling Museum.More than 100 local villagers and 15 fire-fighters managed to put out the fire around 3:10 p.m. on Saturday. About 30 trees and a few shrubs were lost to the blaze.Initial investigation showed the fire was caused by a deserted cigarette end in the dry grasses."Although the fire didn't cause any major damage, it reflected an urgent need to educate residents in neighboring villages to guard against fire risks," Fan said.He said lessons should be learnt from the destruction of a 600-year-old Namdaemun gate in Seoul, one of the most treasured landmarks in the Republic of Korea. The two-tiered gate was set ablaze by a man upset over a land dispute.
