XINING, July 31 (Xinhua) -- The surface area of China's largest saltwater lake had grown in size over the past five years amid increased rain and decreased evaporation, an expert from the Qinghai Provincial Center of Geomatics said Saturday.
The surface area of the Qinghai Lake had reached 4,249.3 square kilometers, 4.3 square kilometers more than in 2005, Wang Yuan, deputy director of the center, said.
"The year 2005 was a turning point. Before then, the lake's size was decreasing due to climate change and human activities," Wang said.
The government's environmental protection work had contributed to the increase in surface area, Wang said.
The lake's surface area shrunk more than 300 square kilometers beginning in the 1950s, according to the Qinghai Province Meteorological Sciences Academy.
