Socio-Political

Economic Value Economically, Ulungur Lake is mainly used for aquaculture. As the lake surface has shrunk and mineralization of the water has increased, fish production has declined. This trend has been reversed somewhat by the broadening of a canal to draw water from the Ertix River.

Ecologically, the lake regulates the microclimate and provides storage for water that might otherwise flood human communities.

Major Cities

Watershed Management

Description Numerous projects to increase the flow of water from the Ertix River (73 km from the lake) into the lake are expected to improve Ulungur water quality. Greater enforcement of fishery regulations is planned.
Issues Numerous non-native fish species have been introduced into Ulungur Lake. As the lake shrinks, the water is getting more and more salty. Irrigation tail water running into the lake adds to its salinization. The area of desertification around the lake has enlarged. The area of marshland has decreased.
Other Issues Irrigation
Watershed habitat alteration
Monitoring

Biodiversity Conservation

Description Seventy five species of phytoplankton live in the lake. Overall, the variety of species and number of aquatic organisms in Lake Ulungur has decreased, as has vegetation coverage.
