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.

BEIJING, March 10 -- Tianjin's mayor assured investors Sunday that the city's pilot program, allowing mainlanders to invest in Hong Kong-listed shares, is on track.     "There's a lot of preparation involved. Risk assessment and research is under way to open the door for mainlanders to invest in the Hong Kong stock market," Huang Xingguo, mayor of Tianjin, said Sunday.     "The project's going smoothly, but timing depends on central government approval. I can assure you that Tianjin's status as a pilot city (for financial reform) will not change," he said.     The scheme is in line with the nation's economic development and investor demand and will be an effective way to bring in conversion of the renminbi via capital accounts, Guo Qingping, chief of Bank of China's (BOC) Tianjin branch, said on the sidelines of yesterday's NPC session.     But authorities are cautious about rushing the program through, due to its complexity and risk.     "One risk is hot money flowing into and out of the mainland," Guo said.     BOC was originally expected to be the only financial institution providing the program, but Guo said the details are still being ironed out.     The trial scheme was announced in August last year as a way to diversify mainland investor channels. But it's been put on hold amid the unfolding US subprime crisis and global stock market uncertainty.     Preparation for the program includes payment systems, renminbi conversion, regulation changes as well as extensive risk assessment, Huang said.     Liu Mingkang, chairman of the China Banking Regulatory Commission, told China Daily earlier that no timetable has been set for the pilot scheme, which will allow mainlanders to invest directly in Hong Kong-listed shares. The regulator stressed that more research into the system is needed.     Meanwhile, a timetable is not yet available for Tianjin's new offshore financial center, which is also subject to further research, according to Guo from BOC.

Beijing and Seoul recently signed an agreement to launch a joint program to harness China's eighth-largest desert - the Ulan Buh in North China's Inner Mongolia Autonomous Region.About 15 million yuan (.99 million) will be spent growing trees and building greenhouses to prevent environmental deterioration in the Ulan Buh region, according to officials involved in the project.The Korea International Cooperation Agency (KOICA) has promised million for the project, while the local government will come up with the rest, according to Han Yongguang, deputy chief of Dengkou county, of which almost 80 percent is covered by desert."It is the first time that we have launched a joint program with a governmental institution from the Republic of Korea (ROK) on desert control," said Han, adding that the local government welcomes more international participation in the battle against desertification."We have made big progress in driving back the desert in this region since the 1980s; and international cooperation will help speed up the process of ecological balance." The local government has spent about 400 million yuan in recent years to contain the expansion of the desert, said Han."The cooperation also helps dispel any doubts over China's determination in environmental protection," Han added.Kim Kwang-young, chief of KOICA's China office, said: "I feel the Chinese government has fully recognized the importance of environmental protection."KOICA's collaborative programs in China are mainly focused on the environmental sector including afforestation, prevention of desertification, and joint monitoring of sandstorms, according to Kim.

BEIJING - The world's most populous nation began its week-long Lunar New Year holiday on Wednesday, but hundreds of thousands of people will probably spend the biggest festival of the year in the cold and dark.Currently, more than 3,000 people, including electricians, soldiers and armed police are struggling to repair power lines damaged by prolonged snow, rain and sleet to restore the power supply for Chenzhou, a city of about 4 million in central China's Hunan Province, which started its 12th day of power blackouts and water cuts on Wednesday.Staff workers of Hunan Grid repair the collapsed high-voltage power transmission tower in Changsha, capital of South China's Hunan Province, Feb. 3, 2008. [Xinhua] Wednesday marks the eve of Lunar New Year, known as Spring Festival, the most important festival for family gatherings in China with a population of 1.3 billion."Parts of the power lines have been recovered, and power supply will restore gradually for citizens in Chenzhou starting today," said Huang Qiang, vice general manager of the Hunan Electric Power Company under the State Grid Corporation of China.But power service is not expected to be resumed by 6:00 p.m. Wednesday, in eight counties, including Guiyang, Jiahe in Hunan Province, Zixi, Lichuan, Yihuang and Le'an in Jiangxi Province, Pingtang in Guizhou Province and Ziyuan in the Guangxi Zhuang Autonomous Region, the disaster relief and emergency command center under the State Council, China's cabinet, said in a statement late Tuesday.Freak winter weather featuring prolonged snow, rain and sleet since mid-January in China's eastern, central and southern regions has downed power lines, covered roads with thick ice, brought trains, buses and planes to standstill and stranded millions of people.The snow havoc, the worst in five decades, and even in a century in few areas, has led to deaths, structural collapses, blackouts, accidents, transport problems and livestock and crop losses in 19 provinces, municipalities and autonomous regions, according to the Ministry of Civil Affairs.More than 100 million people have been affected, and at least 60 people have died in the freezing weather.

BEIJING -- The Chinese government on Sunday promulgated a revised decree to strike the activities of driving up prices through hoarding or cheating.The revision was made on the basis of regulations passed in 1999 and amended in February 2006 by the State Council.The new decree, effective as of Sunday, raises the maximum fine to 1 million yuan(US,000), which almost triples the sum in the old regulations, for those who manipulate market prices and ignore the prices advised by the government under emergencies.Commercial associations which deliberately spread rumors on price information can be fined at a maximum of 500,000 yuan. Those who severely violate the decree may have their legal certificates revoked.The State Council and local governments can set profit ratios or price ceilings for key items of goods and services when prices rise too sharp, according to the decree.
