Chinese Academy of Sciences

The Chinese Academy of Sciences is a natural sciences institution.


The Chinese Academy of Sciences (CAS) is the national academy of the People's Republic of China for natural sciences, known as one of the "Two Academies;" the other is the Chinese Academy of Engineering. The Chinese Academy of Sciences functions as a national think tank and academic governing body for the People's Republic of China, offering advisory and appraisal services on issues in the national economy, social development, and science and technology progress. It defines its development strategy as having a greater emphasis on reliance on democratic management, openness, and talent to promote innovative research.

The Academy of Sciences is headquartered in Beijing, China, and is one of the world's largest research organizations, with a network of 104 research institutes. It has been ranked among the top research organizations around the world. The Chinese Academy of Sciences research network includes the University of Science and Technology of China and the University of Chinese Academy of Sciences. The Chinese Academy of Sciences has also created, spun out, or invested in hundreds of commercial enterprises, with Lenovo being one of the more well-known.


As part of their research programs, CAS provides various laboratories, including national labs, state labs, and institution-specific labs. For example, CAS maintains the Hefei National Laboratory for Physical Sciences at the Microscale and the National Synchrotron Radiation Laboratory. Some of the state labs include the State Key Laboratory of Genetic Resources and Evolution, the State Key Lab of Resources and Environmental Information Systems, National Laboratory of Pattern Recognition, and State Key Laboratory of Computer Science. Some of their more local laboratories include the Laboratory of Condensed Matter Theory and Materials Computation, Key Laboratory of Optical Physics, Key Laboratory of Animal Ecology and Conservation Biology, and Key Laboratory of Extreme Conditions Physics.

Research projects

Some research projects undertaken by the Chinese Academy of Sciences have included the Shenguang-II High Power Laser, LAMOST Telescope, Daya Bay Reactor Neutrino Experiment, and Steady High Magnetic Field. Some of the research infrastructure, separate from research laboratories, included in CAS are the Hefei Synchrotron Radiation Facility, China Remote Sensing Satellite Ground Station, Research Vessels, and China Germplasm Bank of Wild Species.

Climate models predict that rainfall variability over wet regions globally will be greatly enhanced by global warming, causing wide swings between dry and wet conditions, according to a joint study by the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) and the Met Office, the UK's national meteorological service.

Plant litter can influence soil organic carbon dynamics via the priming effect, which is defined as changes in soil organic carbon decomposition rates due to increases in microbial growth and activities responding to plant carbon input. Current understanding of priming effect induced by plant litter is overwhelmingly from studies with leaf litter addition, little is known about how root litter decomposes and subsequently the priming effect occurs until now.
