Sanjiangyuan Rule

A regulation on the Sanjiangyuan National Park took effect on August 1, aimed at better protecting the headwaters of three major rivers in China.

The regulation bans mining, logging, hunting and fishing in the national park, which was established in June 2016.

The collection of wildlife bones and eggs without permission within the park is also prohibited, according to the regulation.

Unauthorized scientific research, outdoor advertising, and the use of drones are forbidden within the park.

Those who violate the regulation will be fined between 1,000 yuan ($149) and 200,000 yuan ($29,800).

Sanjiangyuan, which translates as “source of three rivers,” is home to the headwaters of the Yangtze, Yellow and Lancang (Mekong) rivers in northwest China’s Qinghai Province.

Local provincial legislatures passed the regulation in June. on July 28.

The microwave mercury ion clock is currently one of the most accurate tools for measuring time by tracking atomic movement in the microwave range, said Wang Nuanrang, project leader at the company.

It can provide extremely precise measurements of time that can be used in the fields of deep space exploration and satellite navigation.

Wang said scientists will establish an experimental mercury ion clock system to conduct scientific tests within the next four years, promoting the development of the BeiDou system.

Since 2012, China’s self-developed BeiDou system has provided navigation, time and text messaging services in the Asia-Pacific region.

By 2020, BeiDou satellites will form a complete global satellite navigation system, according to the China Satellite Navigation System Committee.
