Radio Quiet Zones in China

Several advanced radio telescopes have been or under constructed in China, such as Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese Spectral Radio Heliograph (CSRH) and Tianma Radio Telescope (TMRT). To optimize the radio environment in which radio astronomy observations are carried out, different Radio Quiet Zones (RQZs) with definitions and management methods have been established in China. RQZs for FAST, CSRH and TMRT are presented briefly in this paper.
