Comprehensive foreign media reports recently，From Stanford University, the United States、Oregon University、Researchers at Brown University published a latest research results in "Nature" magazine，For the first time to global ponds、Lake、The water level fluctuation in the reservoir was evaluated，and analyzed the influence of human activities in it。

The water level of the freshwater body on the bet365 live casino games surface will rise and fall with the season。At the same time，Human behavior is also an important factor affecting the changes in water level。Researchers have collected 227386 lakes worldwide、The water level measurement data of freshwater bodies such as reservoirs。Analysis results show，Lake、Ponds in the dry season、The water level difference between the rainy season is about 0.7 feet; at the same time，The water level of the artificial reservoir is about four times the water level，average of about 2.8 feet。57%of the fluctuation of the surface water reserves Bet365 app download is the reservoir and other water bodies managed by humans，This indicates that human activities have an important influence on the cycle of earth water。Where，Western United States、southern Africa、The water level fluctuated in the reservoir in the Middle East，about 6.5-12.4 feet。Humans have the strongest effect on the management of surface water in these areas，It indicates that the pressure of water resources in these areas is high，It is necessary to strengthen water resources management。

With the development of the economy，Global water resources will be bet365 Play online games more tense。Understand the impact of human activities on the cycle of earth water，It is important for the sustainable use of freshwater resources。Satellite Observation and other technologies for development，It also allows people to more effectively track the long -term regulation and influence of humans on the cycle of the earth，to help people predict future changes。
