- Abstract
Utilize the senior sequences from 2004 to 2016 of the 4 groundwater monitoring holes around Chaiwopu Lake in Xinjiang to observe the water level, precipitation and temperature, then use continuous wavelet and cross wavelet transform method to analyze the periodicity of water level, precipitation and temperature, and the correlation between each other. The results show that the main fluctuation period of groundwater level of Chaiwopu Lake, precipitation and temperature, and the resonance period between them both are 1 years. The groundwater level time-lag of phreatic water is less than that of confined water. The time-lag between precipitation and groundwater level is greater than that between temperature and groundwater level. Through this mathematical statistics, we can almost master the time-lag relationship between the groundwater level with precipitation and temperature, in the later study, it is necessary to strengthen the analysis to the physical mechanism of the interaction between the three factors.
