Qinghai Lake has grown taller and bigger for 20 consecutive years

2024-11-05

Qinghai Lake, the largest inland lake in China, has continuously expanded its water area for 20 years since 2005, with an average annual increase of nearly 20 centimeters in water level. At present, the lake area has recovered to the level of 70 years ago. On September 25th of this year, satellite remote sensing monitoring showed that the water area of Qinghai Lake was 4650.08 square kilometers, an increase of 0.6% year-on-year. The most direct evidence of the growth of Qinghai Lake is that the half body of a statue by the lake has sunk into the water; The passage from the north bank to Bird Island in Qinghai Lake has also been submerged. This statue, built in 2008, is 8.5 meters high and was over 60 meters away from the lake at that time Chen Dehui, Director of the Science and Technology Cooperation Education Department of the Qinghai Lake Scenic Area Protection and Utilization Management Bureau, said, "At that time, tourists could take close photos with the statue. With the rise of water level, the shoreline of the lake has expanded by nearly 200 meters, and currently the exposed part of the statue is less than 3 meters." Qinghai Lake is located in the northeast of the Qinghai Tibet Plateau, with an elevation of 3196 meters above sea level. It is an important water source conservation area and water and gas circulation channel in western China. Regional ecology and climate change have a significant impact on its water body area. Chen Dehui said that in the mid-1950s, the water area of Qinghai Lake remained at around 4600 square kilometers. Subsequently, due to climate change, human activities, and other factors, the area of the lake gradually decreased. In 2004, the water area of Qinghai Lake shrank to 4244.5 square kilometers. The vegetation coverage and the number of rare and endangered wild animals in the lake area have also decreased synchronously. Throughout history, the water area of Qinghai Lake has been in a state of dynamic change. The restorative growth in the past 20 years is related to the increased rainfall in the northwest region and the warm and humid climate of the Qinghai Tibet Plateau in recent years, and is also a positive achievement in the ecological protection and restoration work of the lake area Sun Jianqing, the relevant person in charge of the Qinghai Lake National Nature Reserve Management Bureau, said. At present, the water quality in the main lake area of Qinghai Lake has remained excellent for a long time. Its unique species, Qinghai Lake naked carp, increased from 2592 tons in 2002 to 120300 tons; The number of Przewalski's antelopes in the watershed has increased from 257 in 2004 to over 3400; The number of water birds inhabiting has increased to 606000, reaching the peak since standardized monitoring began in 2007.
