CHANGSHA, April 22 (Xinhua) -- Dongting Lake in central China's Hunan Province is the second-largest freshwater lake in the country. Located on the central region of the Dongting Lake, Datong Lake is known as "the heart of the Dongting."
Due to disorder aquaculture development, the water quality of Datong Lake was once seriously deteriorated.
In January 2018, an aquatic vegetation planting project was launched in Datong Lake area, with a team from Wuhan University providing technical guidance. In order to support the comprehensive water environment management and ecological industry development of Datong Lake, a scientific workstation was established here in April 2019.

Li Yang, a postdoctoral fellow from Wuhan University, has been working at Datong Lake since 2018.
While completing the project experiments, Li Yang and other stationed researchers also regularly monitor the water quality, vegetation and soil dynamics of the Datong Lake basin, laying a good scientific foundation for the next step of lake management.

Nowadays, the water quality of Datong Lake has seen significant improvement, and the coverage area of aquatic vegetation has stabilized at about 50,000 mu (about 3333.33 hectares).
With the improvement of biodiversity, the ecosystem has developed steadily.
During the six years of work in lake management, Li Yang completed his doctoral project in Datong Lake and continued his postdoctoral research here.
Over the years, he has been deeply involved in the local ecological governance and green development, witnessing an impressive transformation of Datong Lake.
