XINING, March 4 (Xinhua) -- A special court for environmental cases has been established in northwest China's Qinghai Province to provide legal service for environmental protection work in the Sanjiangyuan area.

The Sanjiangyuan environmental court, affiliated with the Yushu City People's Court, was approved by the Higher People's Court in Qinghai Province and was established on Tuesday, according to the government of the Tibetan prefecture of Yushu.

The court hired six people to handle environmental protection cases and civil suites related to pollution prevention and environmental damage in the area.

Sanjiangyuan literally means "the source of three rivers," referring to the Yangtze, Yellow, and Lancang (Mekong) rivers. The ecology in the area has degraded due to human activities such as overgrazing.

The environmental court is the first such specialized judiciary organ in the province, said Man Zhifang, vice president of the Higher People's Court in Qinghai Province.

Planning began on a national park in the area last year, aiming to protect the headwaters of the three rivers. It is expected to officially open in 2020.
