The lake of the motherland is getting more and more "expanded", and there have been more than 24 West Lakes in the past 20 years.

We all know that water is a renewable resource and can be regenerated if given enough time. However, due to the abuse of water resources by human beings, water resources are becoming less and less. Whether it is a river or a lake, it is decreasing little by little. However, in our country, this lake is a different thing. Instead of decreasing, it is increasing every year at an alarming rate. This lake is Qinghai Lake, the largest lake in my country. It is located in Qinghai Province, in the northeastern part of the Qinghai-Tibet Plateau. Qinghai Lake was originally a large freshwater lake, which was connected with the Yellow River water system. Later, the river was blocked, and Qinghai became a closed lake and a salt water lake. The water of Qinghai Lake mainly comes from the supply of melting water from alpine ice and snow, and the method is somewhat simple. In the last century, the area of ​​Qinghai Lake has been decreasing. Therefore, Qinghai Lake is predicted to become the second Lop Nur lake, which will eventually die out with the passage of time. Unexpectedly, since this century, the area of ​​Qinghuhai has continued to expand. It is understood that in 2000, the area of ​​Qinghai Lake was measured to be more than 4,256.04 square kilometers. Last year, the area of ​​Qinghai Lake was measured to become 4,435.69 square kilometers. In just 17 years, the area of ​​Qinghai Lake increased by 179.65 square kilometers. This means that Qinghai Lake is growing at a rate of almost 10 square kilometers per year. Taking the 6.4 square kilometers of West Lake as an example, it is equivalent to adding 24 West Lakes to Qinghai over the years. Many people may wonder, why is Qinghai Lake getting bigger and bigger? The main reason for this is due to changes in the environment. Since global warming, the melting of glaciers around the world has accelerated, so a large number of iceberg meltwater poured into Qinghai Lake, resulting in the current situation of the expansion of Qinghai Lake. In fact, the lakes located on the Qinghai-Tibet Plateau are basically growing, but the situation in Qinghai is more obvious. In addition, the local precipitation in Qinghai Lake is increasing. According to data, the local precipitation was only more than 300 mm before, but now it has become more than 400 mm. It is understood that the historical best level of Qinghai Lake is 4,800 square kilometers. Although it has increased by 17 years, the area today still does not exceed the historical best state. I really don't know whether the increase in Qinghai area is a joy or a worry, but because the amount of water in Qinghai Lake has increased, the salinity content of the lake water has decreased, and the water quality is more suitable for fish growth. There are more and more good phenomena.
