Beijing gets population size warning

Beijing's population is approaching the saturation point, Wei Chenlin, director of the municipal bureau of land and resources, said on Tuesday.

The population upper limit for the city, according to the bureau of land and resources, is 18 million. Currently the population has surpassed 16.3 million.

It is estimated that by 2020 the population will be 21 million.

Wei said the present population is already putting great stress on land use.

"It is of great urgency we improve the efficient use of land and resources," he said.

Beijing covers an area of 16,400 sq km, but only 6,000 sq km is exploitable, and it is not being put to good use, Wei said.

"In the first six month of this year, about 5.05 sq km of the 8.8 sq km of newly acquired land was illegally developed in 14 districts and counties of Beijing, taking up 57 percent of the newly acquired land area," Wei said.

The major reasons for this was illegal occupation of land by county governments and property developers.

However, Zhang Yi, an expert from the Institute of Population and Labor Economics, said it was difficult to set an "upper limit" for Beijing's population.

"The population bearing capacity of a city is not determined only by its land resources, but also by its social structure and economic development," he said.

"Beijing still has room for exploitation. If it had more multi-centers in the city, population distribution would be more even and more people could be accommodated," he said.

Zhang, who believes Beijing has the potential to accommodate more people said: "The government should pay more attention to the efficient, scientific use of land to improve the city's population bearing capacity. Disordered development will harm it."

The municipal bureau has vowed to crack down on illegally occupied arable land

China to launch Mars exploration rover in 2009

China will send its first Mars Rover, Yinghuo-1, into space in October next year by a Russian space rocket under a bilateral Mars exploration initiative reached between Russia and China in March this year.

Chen Changya, a Shanghai Space Administration official, also deputy designer-in-chief of China's first Mars rover, disclosed this Wednesday at an ongoing aerospace exhibition held in Shanghai.

According to the deep space exploration plan, Yinghuo-1, a small 110 kilogram spacecraft with an estimated one year life span, is expected to be put into orbit by August 2010, after an 11 month long and 350 million kilometers distant space journey. It will then begin its mission of exploring the surface of the red planet.

Chen says that rather than landing on Mars, China's Yinghuo-1 will collect scientific data while in orbit. It will constantly transmit data back to space headquarters on Earth via a long-distance transmission system. However, the spacecraft will never return to Earth.

With the bilateral Mars exploration initiative in place, Chen adds that China is awaiting cooperative experiments with Russia.

To date, China has already developed 4 sample craft related to the Mars exploration program, two of which have already been transported to Russia. After close test experiments in Russia, Yinghuo-1 will finally stand out from the two sample craft, which, of course, will need improvements while in tests.

Meanwhile, Russia's Mars spacecraft, which will be launched together with the Yinghuo-1, is targeted to land on the red planet.

Back in 1962, former Soviet Union started the history of Mars exploration. In 1964, the American Mariner 4 became the first spacecraft ever to visit the red planet.
