English name: Bosten Lake in Yanqi Basin was called "West Sea" in ancient times and "Fish Sea" in Tang Dynasty. It was named Bosten Lake in the middle of Qing Dynasty. Bohu county, located in the southeast of Yan (Qi) Basin, is the largest freshwater lake in Xinjiang. It is an intermountain subsidence lake located in Yanqi basin. Also known as Bakakachi Lake, the rivers entering the lake mainly come from Kaidu River and Malasitai River in the northwest, with an average annual runoff of 2.68 billion cubic meters, which is discharged from Peacock River in the southwest, with an average annual outflow of 65.438+0.25 billion cubic meters. After passing through tiemenguan Canyon, it enters Korla and finally flows into Lop Nur. The largest hydropower station in Xinjiang was built in tiemenguan. Since the 1960s, due to the increasing industrial and agricultural water consumption in Korla, it is required to increase the amount of lake water discharged every year, resulting in the decline of the water level, the shrinking of the lake surface and the increasing salinity of the lake, which has now evolved into a brackish lake.

To sum up, it is impossible for Bosten Lake to become the five largest freshwater lakes in China because of the change of water quality.

Xingkai Lake, Manchu, was originally an inner lake in China. 1860 After China and Russia signed the Beijing Treaty, it became the boundary lake between China and Russia. Heilongjiang Province belongs to the southeast, China to the north and Russian to the south. It covers an area of 4380 square kilometers. It began to freeze in February. 10? The lake was completely frozen in 15 days. From the end of February to the beginning of March, the ice layer is 0.9 meters thick. Thaw in the middle and late April. There are many swamps around the lake, and there is a lot of silt and humus at the bottom of the lake. The lake is turbid and the transparency is only 60 cm. The lake flows out from the vicinity of Longwang Temple in the northeast, into Songgacha River and into Wusuli River. Rich in fish. It is a national (AAAA level) resort for vacation, health preservation and tourism, and is known as "Oriental Hawaii".

Xingkai Lake was called Meituo Lake in the Tang Dynasty, which is famous for its rich "crucian carp". Because the lake looks like "Qin Yue", the Jin Dynasty was called "Qin Hai in the North"; After the Qing Dynasty, it was changed to Xingkai Lake, which is a shallow lake on the Sino-Russian border. For the Sino-Russian boundary lake. The southeast of Heilongjiang Province is located in the east of Jixi City, Heilongjiang Province, 35 kilometers away from Mishan City. One third of the area in the north is China and the south is Russian. Daxing Kai Hunan is more than 0/00 kilometers long in the north, 60 kilometers wide in the east and west, and covers an area of 4,380 square kilometers. The elevation of the lake is 69 meters, the deepest point is 10 meter, and the total storage capacity is about 24-26 billion cubic meters. Xiaoxingkai Lake is 35 kilometers long from east to west, 4.5 kilometers wide from north to south, with an area of 140 square kilometers and the deepest point of 4-5 meters. North latitude 45 20', east longitude132 40', freezing began in February 65438, and the lake was completely frozen within 10 ~ 15 days. From the end of February to the beginning of March, the ice layer is 0.9 meters thick. Thaw in the middle and late April.

Xingkai Lake was originally one of the largest freshwater lakes in China. Due to historical reasons, it is a great shame for China to become a border lake between China and Russia, so it cannot be called one of the five largest freshwater lakes in China.

Xingkai Lake will become one of the five largest freshwater lakes in China, unless we recover lost ground and defeat foreign powers.
