“Shiyan 1” Research Vessel
“Shiyan 1” is the first research vessel in service that could be considered
as a large-scale CCS classification SWATH catamaran research vessel.
It is equipped with an AC variable frequency electric propulsion system,
with advanced features like whole-vessel noise and vibration reduction,
whole vessel automation, and dynamic positioning, amongst others. These
features are intended to meet the multidisciplinary and interdisciplinary
research needs for ocean water acoustics, physical oceanography, marine
geology, marine biology, marine chemistry, and marine and atmospheric
environmental studies. It can support a wide range of large-scale
observation networks which include layout, observation, control, remote
sensing, and surveillance tasks. It can also carry out research using a
real-time 3-D marine environment monitoring system and comprehensive
information system. It is the most professional and ideal platform for
acoustic disciplines and multidisciplinary marine experimentation.

The Chinese Academy of Sciences (CAS) system of botanical gardens
consists of 13 gardens whose locations represent the breadth of China’s
geography and flora. The Xishuangbanna Tropical Botanical Garden, for
example, represents the Yunnan-Myanmar-Thailand region of the Malesian
subkingdom, while the Kunming Botanical Garden epitomizes the Yunnan
Plateau region of the Sino-Himalayan forest subkingdom. The North China
region of the Sino-Japanese Forest subkingdom is encapsulated by the
Beijing Botanical Garden, and the Turpan Desert Botanical Garden provides
a glimpse into the Songaria region of the Central Asiatic Desert subkingdom.
From its early days, CAS has considered the establishment and maintenance
of botanical gardens as an important strategy for the conservation,

Meridian Space Weather Monitoring Project
This project deploys continent-scale, ground-based arrays of geomagnetic
field, radio, optical, and sounding rocket instrumentation along the 120° E
longitude meridian, and several other stations distributed along the 30° N
latitude line, to monitor the solar-terrestrial coupling and its influence on the
planetary environment.
It can continuously monitor the magnetic field, electric field, density, temperature,
particle composition, and other space environment parameters
from the surface of the Earth into the upper atmosphere, ionosphere, and
magnetosphere, and further out into interplanetary space, more than a
dozen times the radius of the earth.
Based on this project, the International Meridian Circle Program was initiated.

utilization, and sustainable development of China’s plant diversity.
With an emphasis on scientific conservation, the CAS botanical gardens
play leading and essential roles in developing China’s broader network
of botanical gardens. The CAS botanical gardens have successfully
collected and maintained over 21,000 species of native plants in their living
collections, which form a conservation network covering 60% of the plant
species on the Chinese mainland. The collections have been established
based on plant ex-situ conservation principles and often include field
records and ongoing phenologic observations, providing a solid basis for
subsequent scientific research. In recent years, CAS botanical gardens
have made significant achievements in research areas such as ecology,
coevolution, pollination biology, seed biology, and ex-situ conservation,
enabling some of the gardens to approach international standards. The CAS
botanical gardens have also conducted active outreach work in regional in
