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.

Visiting Chinese Premier Wen Jiabao (L) is greeted by Japanese Prime Minister Shinzo Abe upon his arrival at Abe's official residence in Tokyo April 11, 2007. Wen arrived in Japan on Wednesday. [Reuters]TOKYO: Premier Wen Jiabao and his Japanese counterpart Shinzo Abe Wednesday agreed on concrete steps to build mutually beneficial strategic ties. Wen's three-day trip, the first by a Chinese premier in nearly seven years, comes six months after Abe went to Beijing to mend ties chilled by his predecessor Junichiro Koizumi, who repeatedly visited Yasukuni Shrine that honors Japan's war criminals of World War II. Yesterday, the two leaders declared their firm intention to move forward on rebuilding relations, signed agreements on energy and the environment and issued a joint statement that spelt out issues for cooperation. An environmental accord called for the two to work on a successor to the Kyoto Protocol on climate change by 2013. The other agreement committed the two nations to cooperate on developing energy resources and building nuclear power plants in China. In the joint statement, the two vowed to seek ways to jointly develop gas deposits in disputed waters, pursue the denuclearization of the Korean Peninsula, and strengthen defense cooperation. During their talks, Wen said that the history issue is crucial for bilateral relations as it affects the national feeling of the Chinese people. It could be an obstacle to improved ties if not handled well, he added. He urged the Japanese leaders to face up to history and "open up good, forward-looking relations toward a beautiful future". Wen also reiterated China's position on the Taiwan question, hoping the Japanese side can realize the acute sensitivity of the issue and deal with it properly. Abe reiterated Japan's commitment to the principles enunciated in the three joint documents directing bilateral relations. On disputed waters in the East China Sea, the two sides agreed to speed up the negotiation process to seek a solution that is acceptable to both. The two sides pledged to make the area "a sea of peace, cooperation and friendship". Wen arrived in Tokyo just hours after the two countries signed an accord lifting Beijing's four-year ban on Japanese rice imports. China banned imports in 2003, claiming Japanese rice did not meet the requirements of its revised quarantine system. Wen is scheduled to address Japan's parliament today. He will also meet Emperor Akihito and co-chair an inaugural meeting with Abe on a high-level economic dialogue that will involve officials at the ministerial level and above. He will even join in a game of baseball - a popular sport in Japan - tomorrow with college students in western Japan before returning. Meanwhile, Abe accepted an invitation to visit China again this year. Though no timetable has been set, it is widely believed that he will visit in the autumn to attend the celebrations marking the 35th anniversary of the normalization of bilateral relations. His trip is seen as setting the stage for President Hu Jintao's first visit to Japan next year.

KUNMING - A comprehensive research and preservation facility for the germplasm of rare and endangered plants,wild animal species and microorganisms was completed on Sunday in southwest China's Yunnan Province. With an investment of 148 million yuan (US.5 million) over the past two years, the "Southwest China Germplasm Bank of Wild Species" facility was established by the Kunming Institute of Botany (KIB) with the help of the Chinese Academy of Sciences (CAS). "The bank will be a key player in China's biotech industry and a pioneer in the nation's biodiversity conservation and bioresource development strategy," Chen Zhu, vice president of CAS, said at the inauguration ceremony. According to the KIB, the bank sees itself as a leading storage facility of Asian species within 15 years of its foundation, and expects to make significant contributions to the development of the biotech industry and life science research by providing valuable resources, information and expertise. Within the next five years, the bank is expected to collect 6,450 wild species, 4,000 of which will be plant seed species. Within 15 years, its collection will reach 19,000 species. The bank comprises a seed section, an in-vitro micro-propagation unit, a microorganism bank, an animal germplasm bank, a DNA bank, an information center and a garden. Stretching across an undulating landscape and climatic zones ranging from the tropical to the frigid, Yunnan is home to a multitude of plant species linked together by a complex network of phylogenetic relations, and accounts for more than 50 percent of China's plant diversity.

Beijing has fined more than 50 people for spitting in the past week's holiday, a report said on Monday, as Beijing steps up a campaign to "civilize" the city before the 2008 Olympics. Officials also handed out more than 10,000 bags to tourists to try to keep them from littering as inspection teams fanned out across the city's tourist sites during the week-long Labor Day holiday, when hundreds of millions take to the roads. "The Olympics are coming, and we don't want to get disgraced," Xinhua news agency quoted travel guide Huang Xiaohui as saying. Guides had been instructed to remind tourists not to spit, litter or jump queues, and lead an "etiquette discussion" at the end of the tour, the report said, citing a circular issued by the China National Tourism Administration. China also has an official etiquette watchdog, the Spiritual Civilization Steering Committee of the Chinese Communist Party, which aims to curb uncivilized behavior. Chinese officials have expressed concern about rudeness and public spitting habits and launched campaigns to cultivate courtesy and civility, keen to ensure nothing mars Beijing's image during the Olympic Games. Among the initiatives, the 11th day of every month is now "voluntarily wait in line" day, designed to stamp out pushing and shoving in favor of orderly queues.
