Description

Technical Field

[0001] This invention relates to the field of water extraction equipment technology, specifically to a water extraction and separation device for sand dune areas. Background Technology

[0002] Groundwater is a vital resource for the survival of human society, with billions of people worldwide dependent on it. In dune areas, groundwater primarily originates from lateral recharge from oasis areas, precipitation infiltration, river infiltration, and condensation. In typical dune regions such as the Taklamakan, Badain Jaran, Tengger, and Mu Us deserts, groundwater is mainly consumed by evapotranspiration. Apart from lateral recharge, other recharge and discharge volumes are not fully estimated. Therefore, studying the sources, history, and transformation patterns of groundwater recharge in dune areas is crucial for regional development and ecological stability. Extracting soil and groundwater samples from dune areas and conducting hydrochemical ion and isotope analyses is fundamental to this research.
