4月，青海湖迎來一則消息，那就是「央媒看青海」青海湖“長高了”“變胖了”！
However, for this news, many people may see that it is a good thing, but behind this, in fact, it is not that the change of Qinghai Lake is an absolutely good thing, it changes have the results of protection, but there are still some other factors of the problem, there is a chain effect under the change of Qinghai Lake, so this is two-sided.
And its change also illustrates the problem of changes in the Qinghai-Tibet Plateau region, which is not necessarily a good thing, why do you say that? Let's take a look at it step by step.
青海湖是中國最大的內陸鹹水湖，湖面東西最長106千米，南北最寬63千米，周長約360千米，整個湖水面積4625.6平方公里，湖水容量743億立方米，不過，隨著青海湖的改變，變大也事實。
如在2024年12月20日，通過監測數據顯示，青海湖水體面積持續擴大至4650.08平方公里，較2023年同期又增加了28.1平方公里。
Many people may see that this is nothing, but its continuous rise, which accumulates down, will only be more, as the saying goes, "a little adds up", isn't this how it comes?
And this latest data released in 20/0 shows that the water level of this plateau lake has risen for 0 consecutive years, creating the longest continuous growth cycle since this century.
Ma Ping, director of the Ecological Protection and Restoration Division of the Qinghai Lake Scenic Area Protection and Utilization Administration, said that while the water area is expanding, its water level is rising at an average rate of more than 3196 centimeters per year, and the current water level is more than 0 meters above sea level.
According to the data synthesis of multiple departments, you can also take a look, in fact, the process node of change is also very strong, since the monitoring of the water level of Qinghai Lake in 86 years, the water level has shown a trend of first falling and then rising, 0 to 0 years, the water level has dropped from 0.0 meters to 0.0 meters.
But since 20, the water level has continued to rise, that is to say, it has to rise for 0 consecutive years, and the ancient forecast data shows that in the future, the water level of Qinghai Lake will continue to rise, what is the reason for this?
In fact, there are two main ones:
firstIn recent years, Qinghai has continued to increase the ecological protection of Qinghai Lake, the sandy, bare and saline-alkali land in the basin have continued to decrease, the vegetation coverage has increased to 8.0%, and the soil and water conservation capacity has been significantly improved, so that the water disappearance of Qinghai Lake has weakened.
secondThe rise in the water level of Qinghai Lake is due to the intensification of climate warming and humidification on the Qinghai-Tibet Plateau, and the increase of water supply in Qinghai Lake with the intensification of climate warming and humidification.
Statistics show that in 0 years, the average precipitation in the Qinghai Lake basin was 0 mm, showing a spatial distribution pattern of high in the north and low in the south. Compared with the previous year, the precipitation in the basin was 0.0% more, and the southeast of the basin was 0.0% to 0.0% more.
Therefore, these two factors have led to the continuous expansion of Qinghai Lake, however, there are still very serious problems behind the changes in Qinghai Lake.
After the expansion of Qinghai Lake, the problems it brought about also appeared, which is not to say that there is no impact at all, it is indeed well protected, expanded, and the ecosystem has become better, which is a good thing, but its expansion has also brought serious problems, and it is also a problem faced under the great changes of the Qinghai-Tibet Plateau in the future, such as:
After the expansion of Qinghai Lake, some infrastructure has been affected, especially in the area around Qinghai Lake, some farmers and herdsmen's houses and scenic facilities around the lake have been flooded, and a lake shoreline on the north shore is only more than 70 meters away from the Qinghai-Tibet Railway, which has posed a threat to the safety of railway operation.
After the expansion of Qinghai Lake, the habitat and breeding grounds of some waterbirds have shrunk to varying degrees, and the habitat of Przewalski's gazelle has also been affected to a certain extent, which is equivalent to reconstructing the ecosystem.
Therefore, behind Qinghai Lake is not entirely good, there are also bad things, but the most important thing is that behind Qinghai Lake is also the change under the whole system of the Qinghai-Tibet Plateau, because the Qinghai-Tibet Plateau region is also affected by the climate.
As mentioned above, the warming and humidity of the Qinghai-Tibet Plateau is intensifying, which not only affects the small area of Qinghai Lake.
Rather, it has affected the entire Qinghai-Tibet Plateau region, such as the lakes in the Qinghai-Tibet Plateau region are growing wildly, more lakes are forming, and since 1995, the area and volume of lakes on the Qinghai-Tibet Plateau have continued to increase, and the northern lakes have expanded the fastest.
From 7 to 0, due to the impact of climate warming and increased precipitation, the total area of lakes above 0 square kilometers increased from 0 square kilometers to 0 square kilometers, and the water storage increased by 0.0 cubic kilometers.
And under these lakes, if there is instability and sudden collapse, there may be flooding and other problems, after all, we also know that there are many countries that depend on the Qinghai-Tibet Plateau, and this is the root of the problem.
其次就是青藏高原的變暖，也加大了冰川的大規模融化，如在2021年2月，印度北部阿坎德邦一處冰川突然崩裂，從而引發雪崩。
At the same time, rare flash floods occurred in the Aligenga and Allegennda rivers, and a large amount of flood water flowed into the Akhand dam, causing the dam to be washed away by the flood, and it is understood that all 150 workers at a hydropower station near the dam were swept away by the flood.
Therefore, the changes in the Qinghai-Tibet Plateau region have made China, India and other 8 countries around the Qinghai-Tibet Plateau face the problem of the century, but then again, it is actually a century problem encountered by the world.
The reason is very simple, that is, the Qinghai-Tibet Plateau is a region of the earth, and its changes will also bring about a chain effect, just like the lake, which is actually affecting the global trend.
按照研究的說明來看，在較高溫室氣體排放情景條件下，預計到2050年，青藏高原湖泊面積將增加近20%，約8000至9000平方千米。
The expansion of lakes in the Tibetan Plateau attenuates evaporation by increasing heat capacity, among which the larger lakes increase precipitation through large-scale atmospheric circulation, and the expansion of closed lakes is posing risks to infrastructure, human settlements and pastoral sites through overflow and outburst, and may affect the source and sink effect of regional carbon dioxide.
So, the lakes are affecting the water cycle of the major water systems, and they are affecting the source and sink effect of carbon dioxide, which is the pattern that is changing, and it affects the world, and you say that this is the problem of the century.
In fact, this also answers one thing, that is, the entire earth's climate system is together, as long as it is protected and destroyed, then it is still very difficult to protect the earth.
Therefore, we need to work together to reduce the impact of climate change, so as to stabilize the earth's climate change pattern and stabilize the entire region of the Tibetan Plateau.
