BEIJING, Dec. 8 (Xinhua) -- The following is a summary of published science and technology news of China.

NEW TEST SATELLITE

China successfully sent a new test satellite into space from the Jiuquan Satellite Launch Center in northwest China on Wednesday.

The VHF Data Exchange System (VDES) test satellite was launched by a Kuaizhou-11 Y2 carrier rocket at 9:15 a.m. (Beijing Time) and entered the planned orbit.

FUTURE TERRESTRIAL ECOSYSTEMS

A new study has revealed that future terrestrial ecosystems will produce more oxygen for the atmosphere due to climate change and anthropogenic activities.

Researchers from the College of Atmospheric Sciences of Lanzhou University found that the future terrestrial ecosystems will produce more oxygen for the atmosphere when exploring the variation of the modern oxygen cycle.

The oxygen cycle is an essential biogeochemical cycle for all aerobic life on Earth. However, the modern oxygen cycle has experienced a drastic change compared with that in the pre-industrial period, explained Huang Jianping, an academician with the Chinese Academy of Sciences and professor at Lanzhou University.

QINGHAI-TIBET PLATEAU LAKE ICE PHENOLOGY

Chinese scientists have reconstructed a complete dataset of the lake ice phenology of 132 lakes on the Qinghai-Tibet Plateau from 1978 to 2016, said the Chinese Academy of Sciences (CAS).

The dataset was recently presented on the data-sharing platform China's National Tibetan Plateau Data Center (TPDC).

Lake ice phenology is a perceptible indicator reflecting changes in lake thermodynamics in response to global warming. Due to the limitations of conventional ground-based observations, the lake ice phenology over the Qinghai-Tibet Plateau is rarely observed and recorded. Enditem
