Abstract:

Hailiutu River Basin (HRB) is the representative watershed of Maowusu sandy land. This paper takes the basin as a unit to carry out the research, which will provide a scientific basis for the allocation of water resources. In this paper, the new hydrogeological parameter zoning was obtained by innovatively combining the subdivision of aquifer thickness and groundwater depth with wavelet image fusion by systematically analyzing the aquifer distribution and groundwater distribution characteristics of HRB. The results show that the Quaternary and Cretaceous in HRB are the huge thick aquifer system, and the Cretaceous aquifer gradually thickens from south to north. The watershed is rich in groundwater resources. The Kriging index model is suitable for the interpolation of the groundwater level in HRB, and the groundwater level obtained by the model is about 0-43 m, among which the area with groundwater level of more than 3 m accounts for the main part of the basin. The image fusion technology using Symlets wavelet function as discrete wavelet transform has a strong applicability to the hydrogeological parameter zoning of HRB.

Key words: aquifer, groundwater level, partition of hydrogeological parameter, Hailiutu River Basin
